SOC 2.0: A Crystal-Ball Glimpse Of The Next-Generation Security Operations Center

Thanks to some fundamental shifts in security technology and thinking, the day-to-day activities of security professionals in large enterprises could take some sharp turns in the near future, experts say
Tomorrow's SOC will spend less time aggregating events and more time doing proactive monitoring and intelligent correlation of security data.
For years, the SOC has been defined by SIEM tools that collect information about security-related "events" on the network and consolidate that data onto a single monitoring screen. Experts agree these tools aren't going away, but mostm-- even the makers of SIEM systems themselves -- also agree that security monitoring in the next-generation SOC must become smarter than it is today.

"The current security monitoring environment gives you a useful approximation of what's going on," says Gottlieb, of SIEM vendor SenSage. "Most of the [monitoring] technology can't accept data from any source. And even so, there's a huge amount of data in logs and SIEM systems to go through. It's hard to isolate the signal from the noise."

And the data analysis problem isn't getting any easier, Mogull observes. "There's a ton of data in SIEM, but in the end it's only log-level data," he says. "What will be needed down the road is the ability to do network-level analysis, even packet-level analysis, and that's not all going to happen in one single system."

The next-generation SOC will require new technologies that can correlate data from a wide variety of security systems and help present it in a way that enables analysts to more quickly dig through the haystacks of security information and find the needles of data that could indicate a breach. Realistically, the SOC will get smarter not by consolidating on a few security systems and applications, but by improving the ability of analysts to pull relevant data from many different systems and correlate it to find the source of a threat.

"What's really needed is the kind of event correlation that allows you to baseline your network so that you can understand what 'normal' is," says Cisco's Proctor. "If a laptop that previously never communicated outside the building suddenly starts sending data to Brazil, you want to be able to understand when it started and what data is involved." Eventually, that correlation might extend even to physical systems, so that the SOC can recognize patterns of usage on secure doors and surveillance cameras as well, he says.

In addition, the next-generation SOC staff of the future will do more proactive monitoring and less reactive monitoring, according to some experts. While SIEM and event correlation tools may help identify the source of a breach more quickly, they still don't stop the attack from happening, they note.

"I think a vision that says we're already hacked is defeatist -- and a little bit bizarre," says Steve Dauber, vice president of marketing at RedSeal Systems, which makes tools designed to test vulnerabilities in security policy and measure the security posture of an organization. "If you look at the data from the most recent Verizon Breach Investigation Report, you'll see that most breaches occur because companies fail to take some fairly simple steps to secure their systems. What they need are more ways to find those problems proactively, before the breach occurs, rather than analyzing them post-hack."

Avishai Wool, co-founder and CTO of security configuration management tool vendor AlgoSec, agrees. "I don't agree that the perimeter is dead," he says. "There are many ways to more effectively prevent attacks, but we need a lot more automation and a lot better tools. Mortals cannot configure [virtual private networks], which is what a lot of enterprises are trying to do today."

Both RedSeal and AlgoSec are offering tools that enable enterprises to more effectively evaluate the configuration of firewalls and other security systems to help find vulnerabilities and test them against corporate security policies. This proactive analysis and testing, along with traditional vulnerability scanning, is designed to help companies find the holes in their security systems before the bad guys can exploit them.

Mogull suggests that some existing tools, such as data leak prevention (DLP) technology, could also help in identifying potential leaks and preventing sensitive data from leaving the corporate domain. "DLP gets criticism from security people sometimes because there are ways around it," he says. "But the fact is that DLP can be a big help in egress filtering and identifying advanced persistent threats. There are a lot of bad actors involved [in breaches], and not all of them are smart."

Tomorrow's SOC will spend more time working with security service providers and less time in "do it yourself" activities.
By almost all measures, the volume and complexity of security threats is growing at a breakneck pace. In figures releasef today, Dasient is reporting that there are more than 1.2 million malware-infected websites on the Internet, more than twice as many as there were a year ago. Statistics released last week by CompTIA indicate that nearly two-thirds of enterprises have experienced at least one breach in the past 12 months.

Yet the human and budget resources devoted to IT security are barely increasing at all. In a study released in June, Gartner reported that security spending decreased from 6 percent of the overall IT budget in 2009 to 5 percent this year. Clearly, tomorrow's SOC cannot hope to keep up with the growing threat environment solely by adding more in-house staff and technology.

For this reason, many enterprises are looking toward security services to help them handle some elements of their defense, experts say. While software-as-a-service offerings from major security vendors, such as RSA, Cisco and Symantec, continue to increase in popularity, smaller startups, such as Immunet, FireEye, and Invincea, are building their businesses around services, rather than software.

"Companies are seeing that deploying client-side technology and constantly patching doesn't always work," says Daswani of Dasient, another service-based provider. "I'm not convinced that all of the right endpoint security tools are even available yet. We're seeing some real efficiencies in looking at these problems from the server side."

Research from IDC indicates that the security services market will grow from $32.3 billion worldwide this year to $44.1 billion in 2010. While many of these services will be used by small and midsize enterprises, SOCs in large enterprises will also be looking to leverage the data that is collected by security vendors on malware and other threats, experts say.

But that doesn't mean the expertise of the SOC staff will become less important, experts say. In fact, most experts agree the next-generation security analyst will have to be smarter than ever -- not only about current threats, but about their potential impact on his or her specific business environment.

"The industry's hope to staff the SOC with cheap labor is over," SenSage's Gottlieb quipped. "Security is not going to get simpler. The security staff of the future is going to need expertise not only about the domain they're defending, but also contextual expertise to determine what combinations of events might present a threat. On top of that, they're going to need analytical expertise so that they can determine the source of the threat -- and how to stop it."
