Catch More Threats

The Gartner hype cycle is a graphic “source of insight to manage technology deployment within the context of your specific business goals.” If you have already adopted Security Information and Event Management (SIEM) (aka log management) technology in your organization, how is that working for you? As candidate, Reagan famously asked “Are you better off than you were four years ago?”
Sadly, many buyers of this technology are wallowing in the “trough of disillusionment.” The implementation has been harder than expected, the technology more complex than demonstrated, the discipline required to use/tune the product is lacking, resource constraints, hiring freezes and the list goes on.
What next? Here are some choices to consider.
Do nothing: Perhaps the compliance check box has been checked off; auditors can be shown the SIEM deployment and sent on their way; the senior staff on to the next big thing; the junior staff have their hands full anyway; leave well enough alone.
Upside: No new costs, no disturbance in the status quo.
Downside: No improvements in security or operations; attackers count on the fact that even if you do collect log SIEM data, you will never really look at it.
Abandon ship: Give up on the whole SIEM concept as yet another failed IT project; the technology was immature; the vendor support was poor; we did not get resources to do the job and so on.
Upside: No new costs, in fact perhaps some cost savings from the annual maintenance, one less technology to deal with.
Downside: Naked in the face of attack or an auditor visit; expect an OMG crisis situation soon.
Try managed service: Managing a SIEM is 99% perspiration and 1% inspiration;offload the perspiration to a team that does this for a living; they can do it with discipline (their livelihood depends on it) and probably cheaper too (passing on savings to you); you deal with the inspiration.
Upside: Security usually improves; compliance is not a nightmare; frees up senior staff to do other pressing/interesting tasks; cost savings.
Downside: Some loss of control.

Jill Dyche writing in the Harvard Business Review suggests that “the question on many business leaders’ minds is this: Does the potential for accelerating existing business processes warrant the enormous cost associated with technology adoption, project ramp up, and staff hiring and training that accompany Big Data efforts?”
A typical log management implementation, even in a medium enterprise is usually a big data endeavor. Surprised? You should not be. A relatively small network of a dozen log sources easily generates a million log messages per day with volumes in the 50-100 million per day being commonplace. With compliance and security guidelines requiring that logs be retained for 12 months or more, pretty soon you have big data.
So let’s answer the question raised in the article:
Q1: What can’t we do today that Big Data could help us do? If you can’t define the goal of a Big Data effort, don’t pursue it.
A1: Comply with regulations like PCI-DSS, SOX 404, and HIPAA etc.; be alerted to security problems in the enterprise; control data leakage via insecure endpoints; improve operational efficiency
Q2: What skills, technologies, and existing data development practices do we have in place that could help kick-start a Big Data effort? If your company doesn’t have an effective data management organization in place, adoption of Big Data technology will be a huge challenge.
A2: Absent a trained and motivated user of the power tool that is the modern SIEM, an organization that acquires such technology is consigning it to shelf ware. Recognizing this as a significant adoption challenge in our industry, we offer Monitored SIEM as a service; the best way to describe this is SIEM simplified! We do the heavy lifting so you can focus on leveraging the value.
Q3: What would a proof-of-concept look like, and what are some reasonable boundaries to ensure its quick deployment? As with many other proofs-of-concept the “don’t boil the ocean” rule applies to Big Data.
A3: The advantage of a software-only solution like EventTracker is that an on premises trial is easy to set up. A virtual appliance with everything you need is provided; set up as a VMware or Hyper-Virtual machine within minutes. Want something even faster? See it live online.
Q4: What determines whether we green light Big Data investment? Know what success looks like, and put the measures in place.
A4: Excellent point; success may mean continuous compliance; a 75% reduction in cost of compliance; one security incident averted per quarter; delegation of log review to a junior admin.
Q5: Can we manage the changes brought by Big Data? With the regular communication of tangible results, the payoff of Big Data can be very big indeed.
A5: EventTracker includes more than 2,000 pre-built reports designed to deliver value to every interested stakeholder in the enterprise ranging from dashboards for management, to alerts for Help Desk staff, to risk prioritized incident reports for the security team, to system uptime and performance results for the operations folk and detailed cost savings reports for the CFO.
The old adage “If you fail to prepare, then prepare to fail” applies. Armed with these questions and answers, you are closer to gaining real value with Big Data.

Among InfoSec and IT staff, there is a lot of behind-the-scenes hand wringing that users are the weakest link. But are InfoSec staff that much stronger?
While automation is and does have a place, Dan Geer, of CIA-backed venture fund In-Q-Tel, properly notes that while ” …humans can build structures more complex” than they can operate, ” …Are humans in the loop a failsafe or a liability? Is fully automated security to be desired or to be feared?”
We’ve considered this question before at Prism, when “automated remediation” was being heavily touted as a solution for mid-market enterprises, where IT staff is not abundant. We’ve found that human intervention is not just a fail-safe, but a necessity. The interdependencies, even in medium sized networks are far too complex to automate. We introduced the feature a couple of years back and in reviewing the usage, concluded that such “automated remediation” does have a role to play in the modern enterprise. Use cases include changes to group membership in Active Directory, unrecognized processes, account creation where the naming convention is not followed or honeypot access. In other words, when the condition can be well defined and narrowly focused, humans in the loop will slow things down. However for every such “rule” there are hundreds more that will be obvious to a human but missed by the narrow rule.
So are humans in the loop a failsafe or a liability? It depends on the scenario.
What’s your thought?

The three basic ingredients of any business are technology, processes and people. From an IT security standpoint, which of these is the weakest link in your organization? Whichever it is, it is likely to be the focus of attack.
Organizations around the globe routinely employ the use of powerful firewalls, anti-virus software and sophisticated intrusion-detection systems to guard precious information assets. Year in and year out, polls show the weakest link to be processes and the people behind them. In the SIEM world, the absence of a process to examine exception reports to detect non-obvious problems is one manifestation of process weakness.
The reality is that not all threats are obvious and detected/blocked by automation. You must apply the human element appropriately.
Another is to audit user activity especially privileged user activity. It must match approved requests and pass the reasonableness test (eg performed during business hours).
Earlier this decade, the focus of security was the perimeter and the internal network. Technologies such as firewalls and network based intrusion detection were all the rage. While these are necessary, vital even, defense in depth dictates that you look carefully at hosts and user activity.
