Catch More Threats
July 30, 2014
The cliché goes “When you assume, you make an ass out of u and me.” When implementing a SIEM solution, these five assumptions have the potential to get us in trouble. They stand in the way or organization and personal success and thus are best avoided.
5. Security by obscurity or my network is too unimportant to be attacked
Small businesses tend to be more innovative and cost-conscious. Is there such a thing as too small for hackers to care? In this blog post we outlined why this is almost never the case. As the Verizon Data Breach shows year in and year out, companies with 11-100 employees from 36 countries had the maximum number of breaches.
4. I’ve got to do it myself to get it right
Charles De Gaulle on humility “The graveyards are full of indispensable men”. Everyone tries to demonstrate multifaceted skill but its neither effective nor efficient. Corporations do it all the time. Tom Friedman explains it in “The World is Flat.”
3. Compliance = Security
This is only true if your auditor is your only threat actor. We tend to fear the known more than the unknown so it is often the case that we fear the (known) auditor more than we fear the (unknown) attacker. Among the myriad lessons from the Target breach, perhaps the most important is that “Compliance” does NOT equal Security.
2. All I have to do it plug it in, the rest happens by magic
Marketing departments of every security vendor would have you believe this of their magic appliance or software. When has this ever been true? Self-propelling lawn mower anyone?
1. It’s all about buying the most expen$ive technology
Kivas Fajo in “The Most Toys” the 70th episode of Star Trek TNG believed this. You could negotiate a 90% discount on a $200K solution and then park it as shelfware, what did you get? Wasted $20K is what. It’s always about using what you have.
Bad assumptions = bad decisions.

Return on investment (ROI) — it is the Achilles heel of IT management. Nobody minds spending money to avoid costs, prevent disasters, and ultimately yield more than the initial investment outlay. But is the investment justified? It is challenging to calculate the ROI for any IT investment, and security information and event management (SIEM) tools are no exception. We recently explored some basic precepts or “pillars” of the ROI of SIEM tools and technology. These pillars provide some sensible groundwork for the difficult endeavor to justify intangible costs of SIEM tools and technology.

The three sides of the security triangle are People, Processes and Technology.
None of this is particularly new to CIOs and CSOs, yet how often have you seen six or seven digit “investments” sitting on datacenter racks, or even sometimes on actual storage shelves, unused or heavily underused? Organizations throw away massive amounts of money, then complain about “lack of security funds” and “being insecure.” Buying security technologies is far too often an easier task than utilizing them, and “operationalizing” them for many organizations. SIEM technology suffers from this problem as do many other “Monitoring” technologies.
Compliance and “checkbox mentality” makes this problem worse as people read the mandates and only pay attention to sections that refer to buying boxes.
Despite all this rhetoric, many managers equate information security with technology, completely ignoring the proper order. In reality, a skilled engineer with a so-so tool, but a good process is more valuable than an untrained person equipped with the best of tools.
As Gartner analyst Anton Chuvakin notes, “…if you got a $200,000 security appliance for $20,000 (i.e. at a steep 90% discount), but never used it, you didn’t save $180k – you only wasted $20,000!”
Security is not something you BUY, but something you DO.

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 “220.127.116.11″ 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.
