At RSAC, SOC 'Sees' User Behaviors

RSA CONFERENCE 2018 – San Francisco – At RSAC 2018 the SOC is a demonstration site. It has some hard limits — no visibility to the external IP interfaces being the most significant — but it has tremendous visibility into what happens on the wireless network that supports the tens of thousands of attendees using the open system. And that network visibility translates into great visibility into the behavior of network security professionals in the wild.

A team of network security specialists including Cisco's Jessica Bair staff the SOC, watching traffic of various sorts flow to and from the devices carried by attendees, exhibitors, and staff. Because the SOC isn't blocking any traffic, there's great interest in the monitoring, which happens courtesy of RSA NetWitness Packets; potentially malicious traffic is further given static analysis by Threat Grid.

One of the things visitors notice in the SOC fishbowl is a screen filled with a rolling list of partially obfuscated passwords. That's when they see two important things about conference attendees, one of them good, one of them not so much.

Almost all of the passwords are either strong or very strong. That's great, and shows that security professionals, at least, have acted on the need for stronger passwords.

The problem comes in the fact that the passwords can be seen to be strong; they're being sent in clear text. It's a sign of a lesson half-learned and indicative of problems likely to plague all levels of the computer-using population of companies.

And passwords aren't the only data being sent in the clear. Other examples of documents analysts have seen traversing the network include business plans, resumes, and information on competitors, according to one of the engineers staffing the SOC. 

While the passwords and documents traversing the network represent a significant security risk, Bair quickly points out that there is no threat of long-term information release; the hard disks from the monitoring and analysis appliances are crushed at the end of the conference.

Of course, the monitoring infrastructure established in the SOC sees more that just potentially embarrassing clear text documents. Malware and possible malware were identified and analyzed through Cisco's Advanced Malware Protection (AMP) Anywhere with its Threat Intelligence Cloud. Information on potential malware seen was communicated among all nodes of the security network and other security networks related to the RSA Conference infrastructure for more rapid identification and (potential) remediation.

Ultimately, Bair likened the activity of the SOC to the basic instruction given to fighting women and men of the U.S. Army. "You have to do three things: Shoot, move, and communicate. If you're not doing all three three, you're [redacted] dead."

In cybersecurity terms, the system must actively defend the organization's assets, be agile in shifting its activities to meet evolving threats, and share information and commands with other networks looking for malware and malicious behavior. With all three, an organization has a chance to practice effective behavior. Without the three, then sooner or later your organization is truly [redacted] dead.
