As we deal with forensic reviews of log data, our SIEM Simplified team is called upon to piece together a trail showing the four W’s: Who, What, When and Where. Logs can be your friend and if collected, centralized and indexed can get you answers very quickly.
There is a catch though. The “Where” question is usually answered by supplying either a system name or an IP Address which at the time in question was associated with that system name.
Is that good enough for the law? i.e., will the legal system accept that you are your IP Address?
Florida District Court Judge Ursula Ungaro says no.
Judge Ungaro was presented with a case brought by Malibu Media, who accused IP-address “126.96.36.199″ of sharing one of their films using BitTorrent without their permission. The Judge, however, was reluctant to issue a subpoena, and asked the company to explain how they could identify the actual infringer.
Responding to this order to show cause, Malibu Media gave an overview of their data gathering techniques. Among other things they explained that geo-location software was used to pinpoint the right location, and how they made sure that it was a residential address, and not a public hotspot.
Judge Ungaro welcomed the additional details, but saw nothing that actually proves that the account holder is the person who downloaded the file.
“Plaintiff has shown that the geolocation software can provide a location for an infringing IP address; however, Plaintiff has not shown how this geolocation software can establish the identity of the Defendant,” Ungaro wrote in an order last week.
“There is nothing that links the IP address location to the identity of the person actually downloading and viewing Plaintiff’s videos, and establishing whether that person lives in this district,” she adds.
As a side note, on April 26, 2012, Judge Ungaro ruled that an order issued by Florida Governor Rick Scott to randomly drug test 80,000 Florida state workers was unconstitutional. Ungaro found that Scott had not demonstrated that there was a compelling reason for the tests and that, as a result, they were an unreasonable search in violation of the Constitution.

There are three trends in Enterprise Networks:
1) Internet of Things Made Real. We’re all familiar with the challenge of big data how the volume, velocity and variety of data is overwhelming. Studies confirm the conclusion many of you have reached on your own: There’s more data crossing the internet every second than existed on the internet in total 20 years ago. And, now, as customers deploy more sensors and devices in every part of their business, the data explosion is just beginning. This concept, called the “Internet of Things,” is a hot topic. Many businesses are uncovering efficiencies based on how connected devices drive decisions with more precision in their organizations.
2) “Reverse BYOD.” Most of us have seen firsthand how a mobile workplace can blur the line between our personal and professional lives. Today’s road warrior isn’t tethered to a PC in a traditional office setting. They move between multiple devices throughout their workdays with the expectation that they¹ll be able to access their settings, data and applications. Forrester estimates that nearly 80 percent of workers spend at least some portion of their time working out of the office and 29 percent of the global workforce can be characterized as “anywhere, anytime” information workers. This trend was called “bring your own device” or “BYOD.” But now we¹re seeing the reverse. Business-ready, secure devices are getting so good that organizations are centrally deploying mobility solutions that are equally effective at work and play.
3) Creating New Business Models with the Cloud. The conversation around cloud computing has moved from “if to “when.” Initially driven by the need to reduce costs, many enterprises saw cloud computing as a way to move non-critical workloads such as messaging and storage to a more cost-efficient, cloud-based model. However, the larger benefit comes from customers who identify and grow new revenue models enabled by the cloud. The cloud provides a unique and sustainable way to enable business value, innovation and competitive differentiation all of which are critical in a global marketplace that demands more mobility, flexibility, agility and better quality across the enterprise.

The typical SIEM implementation suffers from TMI, TLA (Too Much Information, Too Little Analysis). And if any organization that’s recently been in the news knows this, it’s the National Security Agency (NSA). The Wall Street Journal carried this story quoting William Binney, who rose through the ranks at the National Security Agency (NSA) over a 30 year career, retiring in 2001. “The NSA knows so much it cannot understand what it has,” Binney said. “What they are doing is making themselves dysfunctional by taking all this data.”
Most SIEM implementations start at this premise – open the floodgates, gather everything because we are not sure what we are specifically looking for, and more importantly, the auditors don’t help and the regulations are vague and poorly worded.
Lt Gen Clarence E. McKnight is the former head of the Signal Corps and opined that “The issue is a straightforward one of simple ability to manage data effectively in order to provide our leaders with actionable information. Too much raw data compromises that ability. That is all there is to it.”
A presidential panel recently recommended the NSA shut down its bulk collection of telephone call records of all Americans. It also recommended creation of “smart software” to sort data as it is collected, rather than accumulate vast troves of information for sorting out later. The reality is that the collection becomes an end in itself, and the sorting out never gets done.
The NSA may be a large, powerful bureaucracy, intrinsically resistant to change, but how about your organization? If you are seeking a way to get real value out of SIEM data, consider co-sourcing that problem to a team that does that for a living. SIEM Simplified was created for just that purpose. Switch from TMI, TLA (Too Much Information, Too Little Analysis) to JEI, JEA (Just Enough Information, Just Enough Analysis).

Top 5 reasons IT Admins love logs:
1) Answer the ‘W’ questions
Who, what, where and when; critical files, logins, USB inserts, downloads…see it all
2) Cut ’em off at the pass, ke-mo sah-bee
Get an early warning of the railroad jumping off track. It’s what IT Admins do.
3) Demonstrate compliance
Don’t even try to demonstrate compliance until you get a log management solution in place. Reduce on-site auditor time by 90%.
4) Get a life
Want to go home on time and enjoy the weekend? How about getting proactive instead of reactive?
5) Logs tell you what users don’t
“It wasn’t me. I didn’t do it.” Have you heard this before? Logs don’t lie.
March 20, 2014
Top 5 Reasons Sys Admins hate logs:
1) Logs multiply – the volume problem
A single server easily generates 0.25M logs every day, even when operating normally. How many servers do you have? Plus you have workstations, applications and not to mention network devices.
2) Log obscurity – what does it mean?
Jan 2 19:03:22 r37s9p2 oesaudit: type=SYSCALL msg=audit(01/02/13 19:03:22.683:318) : arch=i386 syscall=open success=yes exit=3 a0=80e3f08 a1=18800
Do what now? Go where? ‘Nuff said.
3) Real hackers don’t get logged
If your purpose of logging is, for example, to review logs to “identify and proactively address unauthorized access to cardholder data” for PCI-DSS, how do you know what you don’t know?
4) How can I tell you logged in? Let me count the ways
This is a simple question with a complex answer. It depends on where you logged in. Linux? Solaris? Cisco? Windows 2003? Windows 2008? Application? VMware? Amazon EC2?
5) Compliance forced down your throat, but no specific guidance
Have you ever been in the rainforest with no map, creepy crawlies everywhere, low on supplies and a day’s trek to the nearest settlement? That’s how IT guys feel when management drops a 100+ page compliance standard on their desk.

The US Presidential elections of 2012 confounded many pundits. The Republican candidate, Gov. Mitt Romney, put together a strong campaign and polls leading into the final week that suggested a close race. The final results were not so close, and Barack Obama handily won a second term.
Antony Young explains how the Obama campaign used big data, analytics and micro targeting to mobilize key voter blocks giving Obama the numbers needed to push him over the edge.
“The Obama camp in preparing for this election, established a huge Analytics group that comprised of behavioral scientists, data technologists and mathematicians. They worked tirelessly to gather and interpret data to inform every part of the campaign. They built up a voter file that included voter history, demographic profiles, but also collected numerous other data points around interests … for example, did they give to charitable organizations or which magazines did they read to help them better understand who they were and better identify the group of ‘persuadables‘ to target.”
That data was able to be drilled down to zip codes, individual households and in many cases individuals within those households.”
“However it is how they deployed this data in activating their campaign that translated the insight they garnered into killer tactics for the Obama campaign.
“Volunteers canvassing door to door or calling constituents were able to access these profiles via an app accessed on an iPad, iPhone or Android mobile device to provide an instant transcript to help them steer their conversations. They were also able to input new data from their conversation back into the database real time.
“The profiles informed their direct and email fundraising efforts. They used issues such Obama’s support for gay marriage or Romney’s missteps in his portrayal of women to directly target more liberal and professional women on their database, with messages that “Obama is for women,” using that opportunity to solicit contributions to his campaign.
“Marketers need to take heed of how the Obama campaign transformed their marketing approach centered around data. They demonstrated incredible discipline to capture data across multiple sources and then to inform every element of the marketing – direct to consumer, on the ground efforts, unpaid and paid media. Their ability to dissect potential prospects into narrow segments or even at an individual level and develop specific relevant messaging created highly persuasive communications. And finally their approach to tap their committed fans was hugely powerful. The Obama campaign provides a compelling case for companies to build their marketing expertise around big data and micro-targeting. How ready is your organization to do the same?”

Doris Lessing passed away at the end of last year. She was the freewheeling Nobel Prize-winning writer on racism, colonialism, feminism and communism who died November 17 at the age of 94, was prolific for most of her life. But five years ago, she said the writing had dried up. “Don’t imagine you’ll have it forever,” she said, according to one obituary. “Use it while you’ve got it because it’ll go; it’s sliding away like water down a plug hole.”
In the very fast changing world of IT, it is common to feel like an old fogey. Everything changes at bewildering speed. From hardware specs to programming languages to user interfaces. We hear of wunderkinds whose innovations transform our very culture. Think Mozart, Zuckerberg to name two.
Tara Bahrampour examined the idea, and quotes author Mark Walton, “What’s really interesting from the neuroscience point of view is that we are hard-wired for creativity for as long as we stay at it, as long as nothing bad happens to our brain.”
The field also matters.
Howard Gardner, professor of cognition and education at the Harvard Graduate School of Education says, “Large creative breakthroughs are more likely to occur with younger scientists and mathematicians, and with lyric poets, than with individuals who create longer forms.”
In fields like law, psychoanalysis and perhaps history and philosophy, on the other hand, “you need a much longer lead time, and so your best work is likely to occur in the latter years. You should start when you are young, but there is no reason whatsoever to assume that you will stop being creative just because you have grey hair.” Gardner said.
Old dogs take heart; you can learn new tricks as long as you stay open to new ideas.

Over the years, we had a chance to witness a large number of SIEM implementations, with results from the superb to the colossal failures. What is common with the failures? This blog by Keith Strier nails it:
“1) Design Democracy: Find all internal stakeholders and grant all of them veto power. The result is inevitably a mediocre mess. The collective wisdom of the masses is not the best thing here. A super empowered individual is usually found at the center of the successful implementation. If multiple stakeholders are involved, this person builds consensus but nobody else has veto power.
“2) Ignore the little things: A great implementation is a set of micro-experiences that add up to make the whole. Think of the Apple iPhone, every detail from the shape, size, appearance to every icon and gesture and feature converges to enhance the user experience. The path to failure is just focus on the big picture, ignore the little things from authentication to navigation and just launch to meet deadline.
“3) Avoid Passion: View the implementation as non-strategic overhead; implement and deploy without passion. Result? At best, requirements are fulfilled but users are unlikely to be empowered. Milestones may be met but business sponsors still complain. Prioritizing deadlines, linking IT staff bonuses to delivery metrics, squashing creativity is a sure way to launch technology failures that crush morale.”

For any working professional in 2013, multiple screens, devices and apps are integral instruments for success. The multitasking can be overwhelming and dependence on gadgets and Internet connectivity can become a full-blown addiction.
There are digital detox facilities for those whose careers and relationships have been ruined by extreme gadget use. Shambhalah Ranch in Northern California has a three-day retreat for people who feel addicted to their gadgets. For 72 hours, the participants eat vegan food, practice yoga, swim in a nearby creek, take long walks in the woods, and keep a journal about being offline. Participants have one thing in common: they’re driven to distraction by the Internet.
Is this you? Checking e-mail in the bathroom and sleeping with your cell phone by your bed are now considered normal. According to the Pew Research Center, in 2007 only 58 percent of people used their phones to text; last year it was 80 percent. More than half of all cell phone users have smartphones, giving them Internet access all the time. As a result, the number of hours Americans spend collectively online has almost doubled since 2010, according to ComScore, a digital analytics company.
Teens and twentysomethings are the most wired. In 2011, Diana Rehling and Wendy Bjorklund, communications professors at St. Cloud State University in Minnesota, surveyed their undergraduates and found that the average college student checks Facebook 20 times an hour.
So what can Luke Skywalker teach you? Shane O’Neill says it well:
“The climactic Death Star battle scene is the centerpiece of the movie’s nature vs. technology motif, a reminder to today’s viewers about the perils of relying too much on gadgets and not enough on human intuition. You’ll recall that Luke and his team of X-Wing fighters are attacking Darth Vader’s planet-size command center. Pilots are relying on a navigation and targeting system displayed through a small screen (using gloriously outdated computer graphics) to try to drop torpedoes into the belly of the Death Star. No pilot has succeeded, and a few have been blown to bits.
“Luke, an apprentice still learning the ways of The Force from the wise — but now dead — Obi-Wan Kenobi, decides to put The Force to work in the heat of battle. He pushes the navigation screen away from his face, shuts off his “targeting computer” and lets The Force guide his mind and his jet’s torpedo to the precise target.
“Luke put down his gadget, blocked out the noise and found a quiet place of Zen-like focus. George Lucas was making an anti-technology statement 36 years ago that resonates today. The overarching message of Star Wars is to use technology for good. Use it to conquer evil, but don’t let it override your own human Force. Don’t let technology replace you.
Take a lesson from a great Jedi warrior. Push the screen away from time to time and give your mind and personality a chance to shine. When it’s time to use the screen again, use it for good.”

It was the fall of 2008. A variant of a three year old relatively benign worm began infecting U.S. military networks via thumb drives.
Deputy Defense Secretary William Lynn wrote nearly two years later that the patient zero was traced to an infected flash drive that was inserted into a U.S. military laptop at a base in the Middle East. The flash drive’s malicious computer code uploaded itself onto a network run by the U.S. Central Command. That code spread undetected on both classified and unclassified systems, establishing what amounted to a digital beachhead, from which data could be transferred to servers under foreign control. It was a network administrator’s worst fear: a rogue program operating silently, poised to deliver operational plans into the hands of an unknown adversary.
The worm, dubbed agent.btz, caused the military’s network administrators major headaches. It took the Pentagon nearly 14 months of stop and go effort to clean out the worm — a process the military called Operation Buckshot Yankee. It was so hard to do that it led to a major reorganization of the information defenses of the armed forces, ultimately causing the new Cyber Command to come into being.
So what was agent.btz? It was a variant of the SillyFDC worm that copies itself from removable drive to computer and back to drive again. Depending on how the worm is configured, it has the ability to scan computers for data, open backdoors, and send through those backdoors to a remote command and control server.
To keep it from spreading across a network, the Pentagon banned thumb drives and the like from November 2008 to February 2010. You could also disable Windows’ “autorun” feature, which instantly starts any program loaded on a drive.
As Noah Shachtman noted, the havoc caused by agent.btz has little to do with the worm’s complexity or maliciousness — and everything to do with the military’s inability to cope with even a minor threat. “Exactly how much information was grabbed, whether it got out, and who got it — that was all unclear,” says an officer who participated in the operation. “The scary part was how fast it spread, and how hard it was to respond.”
Gen. Kevin Chilton of U.S. Strategic Command said, “I asked simple questions like how many computers do we have on the network in various flavor, what’s their configuration, and I couldn’t get an answer in over a month.” As a result, network defense has become a top-tier issue in the armed forces. “A year ago, cyberspace was not commanders’ business. Cyberspace was the sys-admin guy’s business or someone in your outer office when there’s a problem with machines business,” Chilton noted. “Today, we’ve seen the results of this command level focus, senior level focus.”
What can you learn from Operation Buckshot Yankee?
a) That denial is not a river in Egypt
b) There are well known ways to minimize (but not eliminate) threats
c) It requires command level, senior level focus; this is not a sys-admin business

As we work with various networks to implement IT Security in general and SIEM, Log Management and Vulnerability scanning in particular, we sometimes meet with teams that inform us that they have air gapped networks. An air gap is a network security measure that consists of ensuring physical isolation from unsecured networks (like the Internet for example). The premise here being harmful packets cannot “leap” across the air gap. This type of measure is more often seen in utility and defense installations. Are they really effective in improving security?
A study by the Idaho National Laboratory shows that in the utility industry, while an air gap may provide defense, there are many more points of vulnerability in older networks. Often, critical industrial equipment is of older vintage when insecure coding practices were the norm. Over the years, such systems have had web front ends grated on to them to ease configuration and management. This makes them very vulnerable indeed. In addition these older systems are often missing key controls such as encryption. When automation is added to such systems (to improve reliability or reduce operations cost), the potential for damage is quite high indeed.
In a recent interview, Eugene Kaspersky stated that the ultimate air gap had been compromised. The International Space Station, he said, suffered from virus epidemics. Kaspersky revealed that Russian astronauts carried a removable device into space which infected systems on the space station. He did not elaborate on the impact of the infection on operations of the International Space Station (ISS). Kaspersky doesn’t give any details about when the infection he was told about took place, but it appears as if it was prior to May of this year when the United Space Alliance, the group which oversees the operation of the ISS, moved all systems entirely to Linux to make them more “stable and reliable.”
Prior to this move the “dozens of laptops” used on board the space station had been using Windows XP. According to Kaspersky, the infections occurred on laptops used by scientists who used Windows as their main platform and carried USB sticks into space when visiting the ISS. A 2008 report on ExtremeTech said that a Windows XP laptop was brought onto the ISS by a Russian astronaut infected with the W32.Gammima.AG worm, which quickly spread to other laptops on the station – all of which were running Windows XP.
If the Stuxnet infection from June 2010 wasn’t enough evidence, this should lay the air gap myth to rest.

Who do you fear more – The Auditor or The Attacker? The former plays by well-established rules, gives plenty of prior notice before arriving on your doorstep and is usually prepared to accept a Plan of Action with Milestones (POAM) in case of deficiencies. The latter gives no notice, never plays fair and will gleefully exploit any deficiencies. Notwithstanding this, most small enterprises, actually fear the auditor more and will jump through hoops to minimize their interaction. It’s ironic, because the auditor is really there to help; the attacker, obviously is not.
While it is true that 100% compliance is not achievable (or for that matter desirable), it is also true that even the most basic of steps towards compliance go a long way to deterring attackers. The comparison to the merits of physical exercise is an easy one. How often have you heard it said that even mild physical exercise (taking the steps instead of elevator) gives you benefit? You don’t have to be a gym rat, pumping iron for hours every day.
And so, to answer the question: What comes first, Compliance or Security? It’s Security really, because Compliance is a set of guidelines to help you get there with the help of an Auditor. Not convinced? The news is rife with accounts of exploits which in many cases are at organizations that have been certified compliant. Obviously there is no such thing as being completely secure, but will you allow the perfect to be the enemy of the good?
The National Institutes of Standards (NIST) released Rev 4 of its seminal publication 800-53, one that applies to US Government IT systems. As budgets (time, money, people) are always limited, it all begins with risk classification, applying scarce resources in order of value. There are other guidelines such as the SANS Institute Consensus Audit Guidelines to help you make the most of limited resources.
You may not have trained like Ender Wiggin from a very young age through increasingly difficult games, but it doesn’t take a tactical genius to recognize “Buggers” as attackers and Auditors as the frenemies.

Small and medium business (SMB) owners/managers understand that IT plays a vital role within their companies. However, many SMBs are still making simple mistakes with the management of their IT systems, which are costing them money.
1) Open Source Solutions In a bid to reduce overall costs, many SMBs look to open source applications and platforms. While such solutions appear attractive because of low or no license costs, the effort required for installation, configuration, operation, maintenance and ongoing upgrades should be factored in. The total cost of ownership of such systems are generally ignored or poorly understood. In many cases, they may require a more sophisticated (and therefore more expensive and hard to replace) user to drive them.
2) Migrating to the Cloud Cloud based services promise great savings, which is always music to an SMB manager/owner’s ears, and the entire SaaS market has exploded in recent years. However the costs savings are not always obvious or tangible. The Amazon ec2 service is often touted as an example of cost savings but it very much depends on how you use the resource. See this blog for an example. More appropriate might be a hybrid system that keeps some of the data and services in-house, with others moving to the cloud.
3) The Knowledge Gap Simply buying technology, be it servers or software, does not provide any tangible benefit. You have to integrate it into the day-to-day business operation. This takes expertise both with the technology and your particular business.
In the SIEM space, these buying objections have often stymied SMBs from adopting the technology, despite its benefits and repeated advice from experts. To overcome these, we offer a managed SIEM offering called SIEM Simplified.

Merriam Webster defines “holy grail” as a “goal that is sought after for its great significance”. Mike Rothman of Securosis has described a twofold response to what the “holy grail” is for a security practitioner, i.e.,
How do you achieve the first goal? Here are the steps:
This is a fundamental goal for SIEM systems like EventTracker, and over the ten plus years working on this problem, we’ve got a huge collection of intelligence to draw on to help configure and tune the system to you needs. Even so, there is an undefinable element of luck to have it all work out for you, just when you need it. Murphy’s Law says that luck is not on your side. So now what?
One answer we have found is Anomalous Behavior detection. Learn “normal” behavior during a baseline period and draw the attention of a knowledgeable user to out of ordinary or new items. When you join these two systems, you get coverage for both known-knowns as well as unknown-unknowns.
The second goal involves more discipline and less black magic. If you are familiar with the audit process, then you may know that it’s all about preparation and presentation. The Duke of Wellington famously remarked that the “Battle of Waterloo was won on the playing fields of Eton” another testament to winning through preparation. Here again, to enable diligence, EventTracker Enterprise offers several features including report/alert annotation, summary report on reports, incident acknowledgement and an electronic logbook to record mitigation and incident handling actions.
Of course, all this requires staff with the time and training to use the features. Lack time and resources you say? We’ve got you covered with SIEM Simplified, a co-sourcing option where we do the heavy lifting leaving you to sip from the Cup of Jamshid.
Have neither the time, nor the tools, nor budget? Then the story might unfold like this.

The pervasiveness of Google in the tech world has placed the search function in a central locus of our daily routine. Indeed many of the most popular apps we use every day are specialized forms of search. For example:
And the list goes on.
In the SIEM space, the rise of Splunk, especially when coupled with the promise of “big data”, has led to speculation that SIEM is going to be eclipsed by the search function. Let’s examine this a little more closely, especially from the viewpoint of an expert constrained Small Medium Enterprise (SME) where Data Scientists are not idling aplenty.
Big data and accompanying technologies are, at present, more developer level elements that require assembly with application code or intricate setup and configuration before they can be used by typical system administrators much less mid-level managers. To leverage the big-data value proposition of such platforms, the core skill required by such developers is thinking about distributed computing where the processing is performed in batches across multiple nodes. This is not a common skill set in the SME.
Assuming the assembly problem is somehow overcome, can you rejoice in your big-data-set and reduce the problems that SIEM solves to search queries? Well maybe, if you are a Data Scientist and know how to use advanced analytics. However, SIEM functions include things like detecting cyber-attacks, insider threats and operational conditions such as app errors – all pesky real-time requirements. Not quite so effective as a search on archived and indexed data of yesterday. So now the Data Scientist must also have infosec skills and understand the IT infrastructure.
You can probably appreciate that decent infosec skills such as network security, host security, data protection, security event interpretation, and attack vectors do not abound in the SME. There is no reason to think that the shortage of cyber-security professionals and the ultra-shortage of data scientists and experienced Big Data programmers will disappear anytime soon.
So how can an SME leverage the promise of big-data now? Well, frankly EventTracker has been grappling with the challenges of massive, diverse, fast data for many years before became popularly known as Big Data. In testing on COTS hardware, our recent 7.4 release showed up to a 450% increase in receiver/archiver performance over the previous 7.3 release on the same hardware. This is not an accident. We have been thinking and working on this problem continuously for the last 10 years. It’s what we do. This version also has advanced data-science methods built right in to the EventVault Explorer, our data-mart engine so that security analysts don’t need to be data scientists. Our behavior module incorporates data visualization capabilities to help users recognize hidden patterns and relations in the security data, the so-called “Jeopardy” problem wherein the answers are present in the data-set, the challenge is in asking the right questions.
Last but not the least, we recognize that notwithstanding all the chest-thumping above, many (most?) SMEs are so resource constrained that a disciplined SOC-style approach to log review and incident handling is out of reach. Thus we offer SIEM Simplified, a service where we do the heavy lifting leaving the remediation to you.
Search engines are no doubt a remarkably useful innovation that has transformed our approach to many problems. However, SIEM satisfies specific needs in today’s threat, compliance and operations environment that cannot be satisfied effectively or efficiently with a raw big-data platform.

The Borg are a fictional alien race that are a terrifying antagonist in the Star Trek franchise. The phrase “Resistance is futile” is best delivered by Patrick Stewart in the episode The Best of Both Worlds.
When IBM demonstrated the power of Watson in 2011 by defeating two of the best humans to ever play Jeopardy, Ken Jennings who won 74 games in a row admitted in defeat, “I, for one, welcome our new computer overlords.”
As the Edward Snowden revelations about the collection of metadata for phone calls became known, the first thinking was that it would be technically impossible to store data for every single phone call – the cost would be prohibitive. Then Brewster Kahle, one of the engineers behind the Internet Archive made this spreadsheet to calculate the storage cost to record and store one year’s-worth of all U.S. calls. He works the cost to about $30M which is non-trivial but not out of reach by any means for a large US Gov’t agency.
The next thought was – ok so maybe it’s technically feasible to record every phone call, but how could anyone possibly listen to every call? Well obviously this is not possible, but can search terms be applied to locate “interesting” calls? Again, we didn’t think so, until another N.S.A. document, cited by The Guardian, showed a “global heat map” that appeared to represent how much data the N.S.A. sweeps up around the world. If it were possible to efficiently mine metadata, data about who is calling or e-mailing, then the pressure for wiretapping and eavesdropping on communications becomes secondary.
This study in Nature shows that just four data points about the location and time of a mobile phone call, make it possible to identify the caller 95 percent of the time.
IBM estimates that thanks to smartphones, tablets, social media sites, e-mail and other forms of digital communications, the world creates 2.5 quintillion bytes of new data daily. Searching through this archive of information is humanly impossible, but precisely what a Watson-like artificial intelligence is designed to do. Isn’t that exactly what was demonstrated in 2011 to win Jeopardy?
August 14, 2013
A study published in Nature looked at the phone records of some 1.5 million mobile phone users in an undisclosed small European country, and found it took only four different data points on the time and location of a call to identify 95% of the people. In the dataset, the location of an individual was specified hourly with a spatial resolution given by the carrier’s antennas.
Mobility data is among the most sensitive data currently being collected. It contains the approximate whereabouts of individuals and can be used to reconstruct individuals’ movements across space and time. A simply anonymized dataset does not contain name, home address, phone number or other obvious identifier. For example, the Netflix Challenge provided a training dataset of 100,480,507 movie ratings each of the form <user, movie, date-of-grade, grade> where the user was an integer ID.
Yet, if individual’s patterns are unique enough, outside information can be used to link the data back to an individual. For instance, in one study, a medical database was successfully combined with a voters list to extract the health record of the governor of Massachusetts. In the case of the Netflix data set, despite the attempt to protect customer privacy, it was shown possible to identify individual users by matching the data set with film ratings on the Internet Movie Database. Even coarse data sets provide little anonymity.
The issue is making sure the debate over big data and privacy keeps up with the science. Yves-Alexandre de Montjoye, one of the authors of the Nature article, says that the ability to cross-link data, such as matching the identity of someone reading a news article to posts that person makes on Twitter, fundamentally changes the idea of privacy and anonymity.
Where do you, and by extension your political representative, stand on this 21st Century issue?

If you are old enough to remember the 1988 election in the USA for President, then the name Gary Hart may sound familiar. He was the clear frontrunner after his second Senate term from Colorado was over. He was caught in an extra-marital affair and dropped out of the race. He has since earned a doctorate in politics from Oxford and accepted an endowed professorship at the University of Colorado at Denver.
In this analysis, he quotes President Dwight Eisenhower, “…we must guard against the acquisition of unwarranted influence, whether sought or unsought, by the military-industrial complex. The potential for the disastrous rise of misplaced power exists, and will persist.”
His point is that the US now has an intelligence-industrial complex composed of close to a dozen and a half federal intelligence agencies and services, many of which are duplicative, and in the last decade or two the growth of a private sector intelligence world. It is dangerous to have a technology-empowered government capable of amassing private data; it is even more dangerous to privatize this Big Brother world.
As has been extensively reported recently, the Foreign Intelligence Surveillance Act (FISA) courts are required to issue warrants, as the Fourth Amendment (against unreasonable search and seizure) requires, upon a showing that the national security is endangered. This was instituted in the early 1970s following the findings of serious unconstitutional abuse of power. He asks “Is the Surveillance State — the intelligence-industrial complex — out of the control of the elected officials responsible for holding it accountable to American citizens protected by the U.S. Constitution?
We should not have to rely on whistle-blowers to protect our rights.
In a recent interview with Charlie Rose of PBS, President Obama said, “My concern has always been not that we shouldn’t do intelligence gathering to prevent terrorism, but rather: Are we setting up a system of checks and balances?” Despite this he avoided answering how no request to a FISA court has ever been rejected, that companies that provide data on their customers are under a gag order that even prevents them for disclosing the requests.
Is the Intelligence-Industrial complex calling the shots? Does the President know a lot more than he can reveal? Clearly he is unwilling to even consider changing his predecessor policy.
It would seem that Senator Hart has a valid point. If so, its a lot more consequential than Monkey Business.

The IT team of a Small Business has it the worst. Just 1-2 administrators to keep the entire operation running, which includes servers, workstations, patching, anti-virus, firewalls, applications, upgrades, password resets…the list goes on. It would be great to have 25 hours in a day and 4 hands per admin just to keep up. Adding security or compliance demands to the list just make it that much harder.
The path to relief? Automation, in one word. Something that you can “fit-and-forget”.
You need a solution which gathers all security information from around the network, platforms, network devices, apps etc. and that knows what to do with it. One that retains it all efficiently and securely for later if-needed for analysis, displays it in a dashboard for you to examine at your convenience, alerts you via e-mail/SMS etc. if absolutely necessary, indexes it all for fast search, and finds new or out-of-ordinary patterns by itself.
And you need it all in a software-only package that is quickly installed on a workstation or server. That’s what I’m talking about. That’s EventTracker Log Manager.
Designed for the 1-2 sys admin team.
Designed to be easy to use, quick to install and deploy.
Based on the same award-winning technology that SC Magazine awarded a perfect 5-star rating to in 2013.
How do you spell relief? E-v-e-n-t-T-r-a-c-k-e-r L-o-g M-a-n-a-g-e-r.

At the typical office, computer equipment becomes obsolete, slow etc. and periodically requires replacement or refresh. This includes workstations, servers, copy machines, printers etc. Users who get the upgrades are inevitably pleased and carefully move their data carefully to the new equipment and happily release the older ones. What happens after this? Does someone cart them off the local recycling post? Do you call for a dumpster? This is likely the case of the Small Medium Enterprise whereas large enterprises may hire an electronics recycler.
This blog by Kyle Marks appeared in the Harvard Business Review and reminds us that sensitive data can very well be leaked via decommissioned electronics also.
A SIEM solution like EventTracker is effective when leakage occurs from connected equipment or even mobile laptops or those that connect infrequently. However, disconnected and decommissioned equipment is invisible to a SIEM solution.
If you are subject to regulatory compliance, leakage is leakage. Data security laws mandate that organizations implement “adequate safeguards” to ensure privacy protection of individuals. It’s equally applicable to that leakage comes from your electronic trash. You are still bound to safeguard the data.
Marks points out that detailed tracking data, however, reveals a troubling fact: four out of five corporate IT asset disposal projects had at least one missing asset. More disturbing is the fact that 15% of these “untracked” assets are devices potentially bearing data such as laptops, computers, and servers.
Treating IT asset disposal as a “reverse procurement” process will deter insider theft. This is something that EventTracker cannot help with but is equally valid in addressing compliance and security regulations.
You often see a gumshoe or Private Investigator in the movies conduct Trash Archaeology in looking for clues. Now you know why.

In the aftermath of the disclosure of the NSA program called PRISM by Edward Snowden to a reporter at The Guardian, commentators have gone into overdrive and the most iconic quote is one attributed to Benjamin Franklin “Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety”.
It was amazing that something said over 250 years ago would be so apropos. Conservatives favor an originalist interpretation of documents such as the US Constitution (see Federalist Society) and so it seemed possible that very similar concerns existed at that time.
Trying to get to the bottom of this quote, Ben Wittes of Brookings wrote that it does not mean what it seems to say.
The words appear originally in a 1755 letter that Franklin is presumed to have written on behalf of the Pennsylvania Assembly to the colonial governor during the French and Indian War. The Assembly wished to tax the lands of the Penn family, which ruled Pennsylvania from afar, to raise money for defense against French and Indian attacks. The Penn family was willing to acknowledge the power of the Assembly to tax them. The Governor, being an appointee of the Penn family, kept vetoing the Assembly’s effort. The Penn family later offered cash to fund defense of the frontier–as long as the Assembly would acknowledge that it lacked the power to tax the family’s lands.
Franklin was thus complaining of the choice facing the legislature between being able to make funds available for frontier defense versus maintaining its right of self-governance. He was criticizing the Governor for suggesting it should be willing to give up the latter to ensure the former.
The statement is typical of Franklin style and rhetoric which also includes “Sell not virtue to purchase wealth, nor Liberty to purchase power.” While the circumstances were quite different, it seems the general principle he was stating is indeed relevant to the Snowden case.

Alfred E. Nueman is the fictitious mascot and cover boy of Mad Magazine. Al Feldstein, who took over as editor in 1956, said, “I want him to have this devil-may-care attitude, someone who can maintain a sense of humor while the world is collapsing around him”.
The #1 reason management doesn’t get security is the sense that “It can’t happen to me” or “What, me worry?” The general argument goes – we are not involved in financial services or national defense. Why would anyone care about what I have? And in any case, even if they hack me, what would they get? It’s not even worth the bother. Larry Ponemon writing in the Harvard Business Review captures this sentiment.
Attackers are increasingly targeting small companies, planting malware that not only steals customer data and contact lists but also makes its way into the computer systems of other companies, such as vendors. Hackers might also be more interested in your employees than you’d think. Are your workers relatively affluent? If so, chances are the hackers are way ahead of you and are either looking for a way into your company, or are already inside, stealing employee data and passwords which (as they well know) people tend to reuse for all their online accounts.
Ponemon says “It’s literally true that no company is immune anymore. In a study we conducted in 2006, approximately 5% of all endpoints, such as desktops and laptops, were infected by previously undetected malware at any given time. In 2009—2010, the proportion was up to 35%. In a new study, it looks as though the figure is going to be close to 54%, and the array of infected devices is wider too, ranging from laptops to phones.”
In the recent revelations by Edward Snowden who blew the whistle on the NSA program called “Prism”, many prominent voices have said they are ok with the program and have nothing to hide. This is another aspect of “What, me worry?” Benjamin Franklin had it right many years ago, “Those who would give up essential liberty to purchase a little temporary safety deserve neither liberty nor safety.”

Thinking about implementing analytics? Before you do that, ask yourself “What answers do I want from the data?”
After the Miami Heat lost the 2011 NBA playoffs to the Dallas Mavericks, many armchair MVPs were only too happy to explain that LeBron was not a clutch player and didn’t have what it takes to win championships in this league. Both LeBron and Coach Erik Spolestra however were determined to convert that loss into a teaching moment.
Analytics was indicated. But what was the question? According to Spoelstra, “It took the ultimate failure in the Finals to view LeBron and our offense with a different lens. He was the most versatile player in the league. We had to figure out a way to use him in the most versatile of ways — in unconventional ways.” In the last game of the 2011 Finals, James was almost listlessly loitering beyond the arc, hesitating, shying away, and failing to take advantage of his stature. His last shot of those Finals was symbolic: an ill-fated 25-foot jump shot from the outskirts of the right wing — his favorite 3-point shot location that season.
LeBron decided the correct answer was to work on the post-up game during the off season. He spent a week learning from the great Hakeem Olajuwon. He brought his own videographer to record the sessions for later review. LeBron arrived early for each session and was stretched and ready to go every time. He took the lessons to the gym for the rest of the off season. It worked. James emerged from that summer transformed. “When he returned after the lockout, he was a totally different player,” Spoelstra says. “It was as if he downloaded a program with all of Olajuwon’s and Ewing’s post-up moves. I don’t know if I’ve seen a player improve that much in a specific area in one offseason. His improvement in that area alone transformed our offense to a championship level in 2012.”
The true test of analytics isn’t just on how good they are but in how committed you are in using the data. At the 2012 NBA Finals, LeBron won the MVP title and Miami, the championship.
The lesson to learn here is to know what answers you are seeking form the data and commit to going where the data takes you.

Dan Villasenor describes two classes of cyber threat confronting critical infrastructure. Some, like the power grid, are viewed by everyone as critical, and the number of people who might credibly target them is correspondingly smaller. Others, like the internal networks in the Pentagon, are viewed as a target by a much larger number of people. Providing a high level of protection to those systems is extremely challenging, but feasible. Securing them completely is not.
While I would agree that fewer people are interested/able to hack the power grid, it reminds me of the “insider threat” problem that enterprises face. When an empowered insider who has legitimate access goes rogue, the threat can be very hard to locate and the damage can be incredibly high. Most defense techniques for insider threat depend on monitoring and behavior anomaly detection. Adding to the problem is that systems like the power grid are harder to upgrade and harden. The basic methods to restrict access and enforce authentication and activity monitoring would be applicable. No doubt, this was all true for the Natanz processing plant in Iran and it still got hacked by Stuxnet. That system was apparently infected by a USB device carried in by an external contractor, so it would seem that restricting access and activity monitoring may have helped detect it sooner.
In the second class of threat, exemplified by the internal networks at the Pentagon, one assumes that all classic protection methods are enforced. Situational awareness in such cases becomes important. A local administrator who relies entirely on some central IT team to patrol, detect and inform him in time is expecting too much. It is said that God helps those who help themselves.
Villasenor also says: “There is one number that matters most in cybersecurity. No, it’s not the amount of money you’ve spent beefing up your information technology systems. And no, it’s not the number of PowerPoint slides needed to describe the sophisticated security measures protecting those systems, or the length of the encryption keys used to encode the data they hold. It’s really much simpler than that. The most important number in cybersecurity is how many people are mad at you.”
Perhaps we should also consider those interested in cybercrime? The malware industrial complex is booming and the average price for renting botnets to launch DDoS is plummeting.

A basic requirement for security is that systems be patched and the security products like antivirus be updated as frequently as possible. However, there are practical reasons which limit the application of updates to production systems. This is often the reason why the most active attacks are the ones which have been known for many months.
A new report from the Ponemon Institute polled 3,529 IT and IT security professionals in the U.S., Canada, UK, Australia, Brazil, Japan, Singapore and United Arab Emirates, to understand the steps they are taking in the aftermath of malicious and non-malicious data breaches. Here are some highlights:
On average, it is taking companies nearly three months (80 days) to discover a malicious breach and then more than four months (123 days) to resolve it.
Want an effective defense but wondering where to start? Consider SIEM Simplified.

The news sites are abuzz with reports on Chinese cyber attacks on Washington DC institutions both government and NGOs. Are you a possible target? It depends. Attackers funded by nation states have specific objectives and they will follow these. So if you are a dissident or enabling one, or have secrets that the attacker wants, then you may be a target. A law firm with access to intellectual property may be a target, but an individual has much more reason to fear cyber criminals who seek credit card details than a Chinese attack.
As Sun Tzu noted in the Art of War, “Know your enemy and know yourself, find naught in fear for 100 battles.”
So what are the Chinese after? Ezra Klein has a great piece in the Washington Post. He outlines three reasons:
1) Asymmetric warfare – the US defense budget is larger than the next 13 countries combined and has been that way for a long, long time. In any conventional or atomic war, no conceivable adversary has any chance. An attack on critical infrastructure may help level the playing field. Operators of critical infrastructure and of course US DoD locations are at risk and should shore up defenses.
2) Intellectual property theft – China and Russia want to steal the intellectual property (IP) of American companies, and much of that property now lies in the cloud or on an employee’s hard drive. Stealing those blueprints and plans and ideas is an easy way to cut the costs of product development. Law firms or employees with IP need protection.
3) Chinese intelligence services [are] eager to understand how Washington works. Hackers often are searching for the unseen forces that might explain how the administration approaches an issue, experts say, with many Chinese officials presuming that reports by think tanks or news organizations are secretly the work of government officials — much as they would be in Beijing. This is the most interesting explanation but the least relevant to the security practitioner.
If none of these apply to you, then you should be worried about cyber criminals who are out for financial gain. Classic money-making things like credit cards or Social Security numbers that are used to defraud Visa/Mastercard or perpetrate Medicare fraud. This is by far much more widespread than any other type of hacking.
It turns out that many of the tools and tactics used by all these enemies are the same. Commodity attacks tend to be opportunistic and high volume. Persistent attacks tend to be low-and-slow. This in turn means the defenses for the one would apply to the other and often the most basic approaches are also the most effective. Effective approaches require discipline and dedication most of all. Sadly this is the hardest commitment for small and medium enterprises that are most vulnerable. If this is you, then consider a service like SIEM Simplified as an alternative to do-nothing.

In what probably was his last move as defense secretary, Leon E. Panetta announced on February 13, 2013 the creation of a new type of medal for troops engaged in cyber-operations and drone strikes, saying the move “recognizes the changing face of warfare.” The official description said that it, “may not be awarded for valor in combat under any circumstances,” which is unique. The idea was to recognize accomplishments that are exceptional and outstanding, but not bounded in any geographic or chronologic manner – that is, it’s not taking place in the combat zone. This recognized that people can now do extraordinary things because of the new technologies that are used in war.
On April 16, 2013, barely two months later, incoming Defense Secretary, Chuck Hagel has withdrawn the medal. The medal was the first combat-related award to be created since the Bronze Star in 1944.
Why was it thought to be necessary? Use the case of the mission that got the leader of al-Qaida in Iraq, Abu Musab al-Zarqawi in June 2006. Reporting showed that U.S. warplanes dropped two 500-pound bombs on a house in which Zarqawi was meeting with other insurgent leaders. A U.S. military spokesman said coalition forces pinpointed Zarqawi’s location after weeks of tracking the movements of his spiritual adviser, Sheik Abdul Rahman, who also was killed in the blast. A team of unmanned aerial systems, drone operators, tracked him down. It was over 600 hours of mission operational work that finally pinpointed him. They put the laser target on the compound that he was in, this terrorist leader, and then an F-16 pilot flew six minutes, facing no enemy fire, and dropped the bombs – computer-guided of course – on that laser. The pilot was awarded the Distinguished Flying Cross.
The idea behind the medal was that drone operators can be recognized as well. The Distinguished Warfare Medal was to rank just below the Distinguished Flying Cross. It was to have precedence over — and be worn on a uniform above — the Bronze Star with “V” device, a medal awarded to troops for specific heroic acts performed under fire in combat. It was intended to recognize the magnitude of the achievement, not the personal risk taken by the recipient.
The decision to cancel the medal is more reflective on the uneasiness about the extent to which UAVs are being used in war, rather than questioning the skill and dedication of the operators. In announcing the move, Secretary Hagel said a “device” will be affixed to existing medals to recognize those who fly and operate drones, whom he described as “critical to our military’s mission of safeguarding the nation.” It also did not help that the medal had a higher precedence than a Purple Heart or Bronze Star.
There is no getting away from it, warfare in the 21st Century is increasingly in the cyber domain.

Did you see the NY Times review by John Broder, which was critical about the Tesla Model S? Tesla CEO Elon Musk was not pleased. They are not arguing over interpretations or anecdotal recollections of experiences, instead they are arguing over basic facts — things that are supposed to be indisputable in an environment with cameras, sensors and instantly searchable logs.
The conflicting accounts — both described in detail — carry a lesson for those of us involved in log interpretation. Data is supposed to be the authoritative alternative to memory, which is selective in its recollection. As Bianca Bosker said, “In Tesla-gate, Big Data hasn’t made good on its promise to deliver a Big Truth. It’s only fueled a Big Fight.”
This is a familiar scenario if you have picked through logs as a forensic exercise. We can (within limitations) try and answer four of the five W questions – Who, What, When and Where, but the fifth one -Why- is elusive and brings the analyst of the realm of guesswork.
The Tesla story is interesting because interested observers are trying to deduce why the reporter was driving around the parking lot – to find the charger receptacle or to deliberately drain the battery and make for a bad review. Alas the data alone cannot answer this question.
In other words, relying on data alone, big data included, to plumb human intention is fraught with difficulty. An analyst needs context.

In Jacobellis v. Ohio (1964), Justice Potter Steward was quoted as saying, “I don’t know what porn is, but I’ll know it when I see it.” This is not dissimilar to the position that many business leaders confront the concept of “risk”.
When a business leader can describe and identify the risk they are willing to accept, then the security team can put appropriate controls in place. Easy to say, but so very hard to do. It’s because the quantification and definition of risk varies widely depending on the person, the business unit, the enterprise and also the vertical industry segment.
What is the downside of not being able to define risk? It leaves the security team guessing about what controls are appropriate. Inadequate controls expose the business to leakage and loss, whereas onerous controls are expen$ive and even offensive to users.
What do you do about it? Communication between the security team and business stakeholders is essential. We find that scenarios that demonstrate and personalize the impact of risk resonate best. It’s also useful to have a common vocabulary as the language divide between the security team and business stakeholders is a consistent problem. Where possible, use terminology that is already in use in the business instead of something from a standard or framework.

5 telltale signs that your data security is failing and what you can do about it:
1) Security controls are not proportional to the business value of data
Protecting every bit of data as if it’s a gold bullion in Ft. Knox is not practical. Controls complexity (and therefore cost) must be proportional to the value of the items under protection. Loose change belongs on the bedside table; the crown jewels belong in the Tower of London. If you haven’t classified your data to know which is which, then the business stakeholders have no incentive to be involved in its protection.
2) Gaps between data owners and the security team
Data owners usually only understand business processes and activities and the related information – not the “data”. Security teams, on the other hand, understand “data” but usually not its relation to the business, and therefore its criticality to the enterprise. Each needs to take a half step into the others’ domain.
3) The company has never been penalized
Far too often, toothless regulation encourages a wait-and-see approach. Show me an organization that has failed an audit and I’ll show you one that is now motivated to make investments in security.
4) Stakeholders only see value in sharing, not the risk of leakage
Data owners get upset and push back against involving security teams in the setup of access management. Open access encourages sharing and improves productivity, they say. It’s my data, why are you placing obstacles in its usage? Can your security team effectively communicate the risk of leakage in terms that the data owner can understand?
5) Security is viewed as a hurdle to be overcome
How large is the gap between the business leaders and the security team? The farther apart they are, the harder it is to get support for security initiatives. It helps to have a champion, but over-dependence on a single person is not sustainable. You need buy-in from senior leadership.

In this blog post, Mike Rothman described the quandary facing the midsize business. With a few hundred employees, they have information that hackers want to and try to get but not the budget or manpower to fund dedicated IT Security types, nor the volume of business to interest a large outsourcer. This puts them in no-man’s land with a bull’s-eye on their backs. Hackers are highly motivated to monetize their efforts and will therefore cheerfully pick the lowest hanging fruit they can get. It’s a wicked problem to be sure and one that we’ve been focused on addressing in our corner of the IT Security universe for some years now.
Our solution to this quandary is called SIEM SimplifiedSM and stems from the acceptance that as a vendor we could go developing all sorts of bells and whistles to our product offering only to see an ever shrinking percent of users actually use them in the manner they were designed. Why? Simply put, who has the time? Just as Mike says, our customers are people in mid-size businesses, wearing multiple hats, fighting fires and keeping things operational. SIEM Simplified is the addition of an expert crew at the EventTracker Control Center, in Columbia MD that does the basic blocking and tackling which is the core ingredient if you want to put points on the board. By sharing the crew across multiple customers, it reduces the cost for customers and increases the likelihood of finding the needle in the haystack. And because it’s our bread and butter, we can’t afford to get tired or take a vacation or fall sick and fall behind.
A decade-long focus on this problem as it relates to mid-size businesses has allowed us to tailor the solution to such needs. We use the behavior module to quickly spot new or out-of-ordinary patterns, and a wealth of existing reports and knowledge to do the routine but essential legwork of log review. Mike was correct is pointing out that “folks in security no-man’s land need …. an advisor to guide them … They need someone to help them prioritize what they need to do right now.” SIEM Simplified delivers.

Online shopping continues to bring more and more business to “e-tailers.” Comscore says there was a 16% increase in holiday shopping this past season over the previous season. Some of this is attributed to “recommendations” that are helpfully shown by the giants of the game such as Amazon.
Here is how Amazon describes its recommendation algorithm. “We determine your interests by examining the items you’ve purchased, items you’ve told us you own items you’ve rated, and items you’ve told us you like. We then compare your activity on our site with that of other customers, and using this comparison, are able to recommend other items that may interest you.”
Did you know that EventTracker has its own recommendation engine? It’s called Behavior Correlation and is part of the EventTracker Enterprise. Just as Amazon, learns about your browsing and buying habits and uses it to “suggest” other items, so also, EventTracker auto-learns what is “normal” in your enterprise during an adaptive learning period. This can be as short as 3 days or as long as 15 days depending on the nature of your network. In this period, various items such as IP addresses, users, administrators, process names machines, USB serial numbers etc. are learned. Once learning is complete, data from the most recent period is compared to the learned behavior to pinpoint both unusual activities as well as those never-before-seen. EventTracker then “recommends” that you review these to determine if they point to trouble.
Learning never ends, so the baseline is adaptive, refreshing itself continuously. User defined rules can also be implemented wherein the comparison periods are not learned but specified, and comparisons performed not once a day but as frequently as once a minute.
If you shop online and feel drawn to a “recommendation”, pause to reflect how this concept can also improve your IT security by looking at logs.

Based on early media reports, the Cyber Security executive order would seem to portend voluntary compliance on the part of U.S. based companies to implement security standards developed in concert with the federal government. Setting aside the irony of an executive order to voluntarily comply with standards that are yet to be developed, how should private and public sector organizations approach cyber security given today’s exploding threatscape and limited information technology budgets? How best to prepare for more bad guys, more threats, more imposed standards with less people, time and money?
Back to basics. First let’s identify the broader challenges: of course you’re watching the perimeter with every flavor of firewall technology and multiple layers of IDS, IPS, AV and other security tools. But don’t get too comfortable: every organization that has suffered a damaging breach had all those things too. Since every IT asset is a potential target, every IT asset must be monitored. Easy to describe, hard to implement. Why?
Challenge number one: massive volumes of log data. Every organization running a network with more than 100 nodes is already generating millions of audit and event logs. Those logs are generated by users, administrators, security systems, servers, network devices and other paraphernalia. They generate the raw data that tracks everything going on from innocent to evil, without prejudice.
Challenge number two: unstructured data. Despite talk and movement toward audit log standards, log data remains widely variable with no common format across platforms, systems and applications, and no universal glossary to define tokens and values. Even if every major IT player from Microsoft to Oracle (and HP and Cisco), along with several thousand other IT organizations were to adopt uniform, universal log standards today, we would still have another decade or two of the dreaded “legacy data” with which to contend.
Challenge number three: cryptic or non-human readable logs. Unstructured data is difficult enough, but further adding to the complexity is that most of the log data content and structure are defined by developers for developers or administrators. Don’t assume that security officers and analysts, senior management, help desk personnel or even tenured system administrators can quickly and accurately glance at a log and immediately understanding its relevance or more importantly what to do about it.
Solution? Use what you already have more wisely. Implement a log monitoring solution that will ingest all of the data you already generate (and largely ignore until after you discover there’s a real problem), process it in real-time using built-in intelligence, and present the analysis immediately in the form of alerts, dashboards, reports and search capabilities. Take a poorly designed and voluminous asset (audit logs) and turn it into actionable intelligence. It isn’t as difficult as it sounds, though it require rigorous discipline and a serious time commitment.
Cyber criminals employ the digital equivalent of what our military refers to as an “asymmetrical tactic.” Consider a hostile emerging super power in Asia that directly or indirectly funds a million cyber warriors at the U.S. equivalent of $10 a day; cheap labor in a global economy. No organization, not even the federal government, the world’s largest bank or a 10 location retailer, has unlimited people, time and money to defend against millions of bad guys attacking on a much lower (asymmetrical) operational budget.

The value proposition of our SIEM Simplified offering is that you can leave the heavy lifting to us. What is undeniable is that getting value from SIEM solutions requires patient sifting through millions of logs, dozens of reports and alerts to find nuggets of value. It’s quite similar to detective work.
But does that not mean you are somehow giving up power? Letting someone else get a claw hold in your domain?
Valid question, but consider this from Nilofer Merchant who says “In the Social Era, value will be (maybe even already is) no longer created primarily by people who work for you or your organization“.
Isn’t power about being the boss?
The Social Era has disrupted the traditional view of power which has always been your title, span of control and budget. Look at Wikipedia or Kickstarter where being powerful is about championing an idea. With SIEM Simplified, you remain in control, notified as necessary, in charge of any remediation.
Aren’t I paid to know the answer?
Not really. Being the keeper of all the answers has become less important with the rise of fantastic search tools and the ease of sharing, as compared to say even 10 years ago. Merchant says “When an organization crowns a few people as chiefs of answers, it forces ideas to move slowly up and down the hierarchy, which makes the organization resistant to change and less competitive. The Social Era raises the pressure on leaders to move from knowing everything to knowing what needs to be addressed and then engaging many people in solving that, together.” Our staff does this every day, for many different environments. This allows us to see the commonalities and bring issues to the fore.
Does it mean blame if there is failure and no praise if it works?
In a crowd sourcing environment, there are many more hands in every pie. In practice, this leads to more ownership from more people than the other way around. Consider Wikipedia as an example of this. It does require different skills, collaborating instead of commanding, sharing power rather than hoarding it. After all, we are only successful, if you are. Indeed, as a provider of the service, we are always mindful that this applies to us more than it does you.
As a provider of services, we see clearly that the most effective engagements are the ones where we can avoid the classic us/them paradigm and instead act as a badgeless team. The Hubble Space Telescope is an excellent example of this type of effort.
It’s a Brave New World, and it’s coming at you, ready or not.

The headlines are ablaze with the news of a new zero-day vulnerability in Java which could expose you to a remote attacker.
The Department of Homeland Security recommends disabling Java completely and many experts are apparently concurring. Crisis communications 101 says maintain high-volume, multi-channel communications but there is a strange silence from Oracle, aside of the announcement of a patch for said vulnerability.
Allowing your opponents to define you is a bad mistake as any political consultant will tell you. Today it’s Java, tomorrow, some other widely used component. The shrillness of the calls also makes me wonder why the hullabaloo? Upset by the Oracle stewardship of Java, perhaps?
So what should you make of the “disable Java” calls echoing across Cyberia? Personally I think it’s bad advice, assuming you can even take the advice in the first place. Java is widespread in server side applications (usually enterprise software) and embedded devices. There is probably no easy way to “upgrade” a heart pump or elevator control or a POS system. As far as server side, this may be easier but spare a thought to backward compatibility and business applications that are “certified” on older browsers. Pause a moment, the vulnerability becomes exposed when you visit a malicious website which can then take advantage of the flaw and get on your machine.
Instead of disabling Java and thereby possibly breaking critical functionality, why don’t you limit access to outside websites instead? This is easily done by configuring proxy servers (good for desktops or mobile situations) or limiting devices to a subnet that only has access to the trusted internal hosts (this can work for bar code scanners or manufacturing equipment). This limits your exposure. Proxy server filtering at the internet perimeter is done by matching the user agent string. This is also a good way to limit those older insecure browsers that must be present for internal applications from accessing the outside and potentially being equally a source of infection in the enterprise.
This is a serious issue that merits a thoughtful response, not a panicked rush to comply and cripple your enterprise.

In January 2010 the U.S. Senate was locked in a sharp debate about the country’s debt and deficit crisis. Unable to agree on a course of action, some Senators proposed the creation of a fiscal commission that would send Congress a proposal to address the problem with no possibility of amendments. It was chaired by former Senator, Alan Simpson, and former White House chief of staff, Erskine Bowles.
Darrel West and Ashley Gabriele of Brookings examined the leadership lessons in this article. I was struck by the application of some of the lessons to the SIEM problem.
1) Stop Fantasizing About Easy Fixes
Cutting waste and fraud is not sufficient to address long-term debt and deficit issues. To think that we can avoid difficult policy choices simply by getting rid of wasteful spending is a fantasy. It’s also tempting to think that the next Cisco firewall, Microsoft OS or magic box will solve all security issues; that the hard work of reviewing logs, changes and assessing configuration will not be needed. It’s high time to stop fantasizing about such things.
2) Facts Are Informative
Senator Daniel Patrick Moynihan famously remarked that “everyone is entitled to his own opinion, but not to his own facts.” This insight often is lost in Washington D.C. where leaders invoke “facts” on a selective or misleading basis. The Verizon Data Breach report has repeatedly shown that attacks are not highly difficult, that most breaches took weeks or more to be discovered and that almost all were avoidable through simple controls. We can’t get away from it — looking at logs is basic and effective.
3) Compromise Is Not a Dirty Word
One of the most challenging aspects of the contemporary political situation is how bargaining, compromise, and negotiation have become dirty words. Do you have this problem in your Enterprise? Between the Security and Compliance teams? Between the Windows and Unix teams? Between the Network and Host teams? Is it preventing you from evaluating and agreeing on a common solution? If yes, this lesson is for you — compromise is not a dirty word.
4) Security and Compliance Have Credibility in Different Areas
On fiscal issues, Democrats have credibility on entitlement reform because of their party’s longstanding advocacy on behalf of Social Security, Medicare, and Medicaid. Meanwhile, Republicans have credibility on defense issues and revenue enhancement because of their party’s history of defending the military and fighting revenue increases. In our world, the Compliance team has credibility on regular log review and coverage of critical systems, while the Security team has credibility on identifying obvious and subtle threats (out-of-ordinary behavior). Different areas, all good.
5) It’s Relationships, Stupid!
Commission leaders found that private and confidential discussions and trust-building exercises were important to achieving the final result. They felt that while public access and a free press were essential to openness and transparency, some meetings and most discussions had to be held behind closed doors. Empower the evaluation team to have frank and open discussion with all stakeholders — including those from Security, Compliance, Operations and Management. Such a consensus built in advance leads to a successful IT project.

In information technology, big data consists of data sets that grow so large they become unwieldy to work with using available database management tools. How big is big? It depends on when you need to reconsider data management options – in some cases it may be 100 Gigabytes, in others, as great as 100 Terabytes.
Does more data necessarily mean more insight?
The pro-argument is that larger data sets allow for greater incidences of patterns, facts, and insights. Moreover, with enough data, you can discover trends using simple counting that are otherwise undiscoverable in small data using sophisticated statistical methods.
On the other hand, while this is perfectly valid in theory, for many businesses the key barrier is not the ability to draw insights from large volumes of data; it is asking the right questions for which insight is needed.
The ability to provide answers does depend on the question being asked and the relevance of the big-data set to that question. How can one generalize to an assumption that more data will always mean more insight? It isn’t always the answer that’s important, but the questions that are key.

In 2010, CBS rebooted the classic series Hawaii Five-O. It features a fictional state police unit run by Detective Steve McGarrett and named in honor of Hawaii’s status as the 50th state. The action centers on a special task force empowered by Hawaii’s governor to investigate serious crime.
The tech guru on the show is a Detective Chin Ho Kelly (played by Daniel Dae Kim) and is shown to be adept at various forensic techniques, including…wait for it…SIEM (of all things).
In Season 1, Episode 15 (Kai e’ e) the island’s leading tsunami expert is kidnapped on the same day that ocean reports indicate that a huge tsunami is headed to Hawaii. However, Five-0 soon suspects that the report is a hoax and is related to the kidnapping.
During the investigation, Chin Ho uncovers two failed logins with the kidnapped expert’s username and a numeric password each time. This is followed by a successful login. This seems odd because the correct password is all alphabetical and totally unrelated to the numbers. Turns out the kidnapped person was trying to send a message to the cops, knowing the failed logins would get scrutiny. The clue is incomplete though, because the failed logins do not capture the originating IP address and so can’t be readily geolocated.
Its great that SIEM is now firmly entrenched in the mainstream….bodes well for our industry and for IT security.
When the bad guys attack your assets, use EventTracker to “book ‘em Danno”.

Windows does not track drive mappings for auditing out of the box. To audit drive mappings you will need to do the following steps:
Windows will now generate event ids 560, 567 and 564 when the drive mappings are added or deleted. 564 will be generated when a mapping is deleted, 567 will be created when a mapping is deleted or added and 560 will be generated both times as well. Event ID’s 567 and 564 will not give you the full information that you are looking for, they will tell you what was done to the mappings but not WHICH mapping. To determine which mapping you will need,the Handle ID code that will be found in the event description on the 564/567 events. The Handle ID will allow you to track back to the 560 event which will give you the mapping that is being added/deleted. Event ID 567 will only be generated on Windows XP or Windows 2003 systems, Windows 2000 will not generate 567.

The Gartner Group has long produced its Hype Cycle for IT technologies to show when technologies begin to offer practical benefits and become widely accepted. In 2006, Security Information and Event Management (SIEM) was located in the ‘Trough of Disillusionment’. This segment of the curve is supposed to represent a technology that has failed to meet expectations and become unfashionable therefore causing less coverage in the press. Gartner predicted emergence into the ‘Slope of Enlightenment’ in 2-5 years.
What can you do to avoid disillusionment?
Three words — Know your requirements
The lack of this is the single largest reason for failure of IT projects.
Basic advice, you say? Amazing how basic advice is the hardest to follow.
Watch the ball, mind your footwork. That sort of thing.
The market is awash with product offerings, each with similar claims but different heritages and usually optimized for different use-cases. Selection criteria should be your own needs. Mature vendors dislike failed projects as much as the sponsors because of the negative energy generated by the failure. Sharing your requirements sets expectations more correctly and therefore reduces the chances of energy sapping failures.
Aside of maturation of the technology itself, the other reason for the ‘trough’ is customer expectation and implementation methodology, which is usually outside vendor control. As SIEM comes into the mainstream, the basics apply more than ever. A mature customer with robust practices will get better results with new technology than those with poor habits get from well established technologies.
As Sun Tzu said, “he who knows neither himself nor his enemy can never win, he who knows himself but does not know his enemy will sometimes win and sometimes lose, but he who knows himself and his enemy will never lose.”
