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.

5. Overdoing compensating controls
When a legitimate technological or documented business constraint prevents you from satisfying a requirement, a compensating control can be the answer after a risk analysis is performed. Compensating controls are not specifically defined inside PCI, but are instead defined by you (as a self-certifying merchant) or your QSA. It is specifically not an excuse to push PCI Compliance initiatives through completion at a minimal cost to your company. In reality, most compensating controls are actually harder to do and cost more money in the long run than actually fixing or addressing the original issue or vulnerability. See this article for a clear picture on the topic.
4. Separation of duty
Separation of duties is a key concept of internal controls. Increased protection from fraud and errors must be balanced with the increased cost/effort required. Both PCI DSS Requirements 3.4.1 and 3.5 mention separation of duties as an obligation for organizations, and yet many still do not do it right, usually because they lack staff.
3. Principle of Least privilege
PCI 2.2.3 says they should “configure system security parameters to prevent misuse.” This requires organizations to drill down into user roles to ensure they’re following the rule of least privilege wherever PCI regulations apply. This is easier said than done; more often it’s “easier” to grant all possible privileges rather than determine and assign just the correct set. Convenience is the enemy of security.
2. Fixating on excluding systems from scope
When you make the process of getting things out of scope a higher priority than addressing real risk, you get in trouble. Risk mitigation must come first and foremost. In far too many cases, out-of-scope becomes out-of-mind. This may make your CFO happy, but a hacker will get past weak security and not care if the system is in scope or not.
And drum roll …
1. Ignoring virtualization
Many organizations have embraced virtualization wholeheartedly given its efficiency gains. In some cases, virtualized machines are now off-premises and co-located at a service provider like Rackspace. This is a trend at federal government facilities. However, “off-premises” does not mean “off-your-list”. Regardless of the location of the cardholder data, such systems are within scope as are the hypervisor. In fact, PCI DSS 2.0 says, if the cardholder data is present on even one VM, then the entire VM infrastructure is “in scope.”

Nearly every analyst has made aggressive predictions that outsourcing to the cloud will continue to grow rapidly. It’s clear that servers and applications are migrating to the cloud as fast as possible, but according to an article in The Economist, the tradeoff is efficiency vs. sovereignty. The White House announced that the federal government will shut down 178 duplicative data centers in 2012, adding to the 195 that will be closed by the end of this year.
Businesses need motivation and capability to recognize business problems, solutions that can improve the enterprise, and ways to implement those solutions. There is clearly a role for outsourced solutions and it is one that enterprises are embracing.
For an engineer, however, the response to outsourcing can be one of frustration, and concerns about short-sighted decisions by management that focus on short term gains at the risk of long term security. But there is also an argument why in-sourcing isn’t necessarily the better business decision: a recent Gartner report noted that IT departments often center too much of their attention on technology and not enough on business needs, resulting in a “veritable Tower of Babel, where the language between the IT organization and the business has been confounded, and they no longer understand each other.”
Despite increased migration to cloud services, it does not appear that there is an immediate impact on InfoSec-related jobs. Among the 12 computer-related job classifications tracked by the Department of Labor’s Bureau of Labor Statistics (BLS), information security analysts, along with computer and information research scientists, were among those whose jobs did not report unemployment during the first two quarters of 2011.
John Reed, executive director at IT staffing firm Robert Half Technology, attributes the high growth to the increasing organizational awareness of the need for security and hands-on IT security teams to ensure appropriate security controls are in place to safeguard digital files and vital electronic infrastructure, as well as respond to computer security breaches and viruses.
Simply put: the facility of using cloud services does not replace the skills needed to analyze and interpret the data to protect the enterprise. Outsourcing to a cloud may provide immediate efficiencies, but it’s the IT security staff who deliver business value that ensure long term security.

Over the past few years you have seen an increasing drumbeat in the IT community to server consolidation through Virtualization with all the trumpeted promises of cheaper, greener, more flexible customer focused data centers with never a wasted CPU cycle. It is a siren song to all IT personnel and quite frankly it actually looks like it delivers on a great many of the promises.
Interestingly enough, while reduced CPU wastage, increased flexibility, fewer vendors are all being trumpeted for servers there continues to be little thought provided to purchasing hardware appliances willy-nilly. Hardware appliances started out as specialized devices built or configured in a certain way to maximize performance – A SAN device is a good example, you might want high speed dual port Ethernet and a huge disk capacity with very little requirement for a beefy CPU or memory. These make sense to be appliances. Increasingly however an appliance is a standard Dell or rack mounted rack mounted system with an application installed on it, usually on a special Linux distribution. The advantages to the appliance vendor are many and obvious — a single configuration to test, increased customer lockin, and a tidy up sell potential as the customer finds their event volume growing. From the customer perspective it suffers all the downsides that IT has been trying to get away from – specialized hardware that cannot be re-purposed, more, locked-in hardware vendors, excess capacity or not enough, wasted power from all the appliances running, the list goes on and on and contains all the very things that have caused the move to virtualization. And the major benefit for appliances? Easy to install seems to be the major one. So to provision a new machine, install software might take an hour or so – the end-user is saving that and the downstream cost of maintaining a different machine type eats that up in short order.
Shortsighted IT managers still manage to believe that, even as they move aggressively to consolidate Servers, it is still permissible to buy an appliance even if it is nothing but a thinly veiled Dell or HP Server. This appliance sprawl represents the next clean-up job for IT managers, or will simply eat all the savings they have realized in server consolidation. Instead of 500 servers you have 1 server and 1000 hardware appliances – what have you really achieved? You have replaced relationships with multiple hardware vendors with multiple appliance vendors and worse when a server blew-up at least it was all Windows/Intel configurations so in general so you could keep the applications up and running. Good luck doing that with a proprietary appliance. This duality in IT organizations reminds me somewhat of people that go to the salad bar and load up on the cheese, nuts, bacon bits and marinated vegetables, then act vaguely surprised when the salad bar regimen has no positive effect.

In life and business, the smart approach is to make the most of what you have. You can work for 8 hours and 10 hours and then 12 hours a day and hit your performance limit. How do you get more out of your work? By working smarter, not harder – Get others on board, delegate, communicate. Nowhere is this truer than with computer hardware. Poorly written software makes increasing demands on resources but cannot deliver quantum jumps in performance.
As we evaluated earlier versions of EventTracker it became clear that we were soon reaching the physical limits of the underlying hardware and the choke point to getting faster reports was not to work harder (optimize Code) but to work smarter (plan up-front, divide and conquer, avoid searching through irrelevant data).
This is realized in the Virtual Collection Point architecture that is available in version 6. By segregating log sources up front into virtual groups and stacking software processes from reception to archiving, improvement in performance is possible FOR THE SAME HARDWARE!
When comparing SIEM solutions for scalability, remember that if the only path is to add more hardware, it’s a weaker approach than making the best of what you already have.
