Network Monitoring Products Reviewed by NWC

A few years ago while consulting for Foundstone I was asked to name a product which would inspect traffic exiting the enterprise. The goal was to identify unauthorized transmission of sensitive documents or data. Aside from a customized signature-based approach, I could not think of any off-the-shelf product with this capability. After reading Monitoring Data Departures by Lori MacVittie in the 27 May 04 issue of NWC, I learned of Vontu's Vontu Protect 3. Some of its claims are amusing, like "No false positives — every incident reported is a genuine policy violation." This is also true for signature-based intrusion detection systems, if one accepts (as I do) that an IDS which alerts based on a rule is merely doing what it was told to do. It's up to a decision maker to guide the policy that an administrator implements, and it's an analyst's responsibility to judge the likelihood that a given event respresents a security incident. If Vontu would like me to take a look at their product, feel free to contact me at blog at taosecurity dot com.

Two weeks earlier, NWC's Well-Connected Awards were published, complete with the most disgusting cover I've ever seen on a technical magazine. That earned the print edition a place in my circular bin, but the security awards were interesting. The "Network Behavior Anomaly Detection" award went to Q1 Labs, whose QVision tool seems to have been renamed QRadar. NWC liked this network behavior visualization product better than similar offerings from Arbor Networks and Lancope. Anyone interested in having me do a technical review of your product, please email blog at taosecurity dot com.

Zeek in Action Videos

Image
This is a quick note to point blog readers to my Zeek in Action YouTube video series for the Zeek network security monitoring project .  Each video addresses a topic that I think might be of interest to people trying to understand their network using Zeek and adjacent tools and approaches, like Suricata, Wireshark, and so on.  I am especially pleased with Video 6 on monitoring wireless networks . It took me several weeks to research material for this video. I had to buy new hardware and experiment with a Linux distro that I had not used before -- Parrot .  Please like and subscribe, and let me know if there is a topic you think might make a good video.

MITRE ATT&CK Tactics Are Not Tactics

Image
Just what are "tactics"? Introduction MITRE ATT&CK  is a great resource, but something about it has bothered me since I first heard about it several years ago. It's a minor point, but I wanted to document it in case it confuses anyone else. The MITRE ATT&CK Design and Philosophy document from March 2020 says the following: At a high-level, ATT&CK is a behavioral model that consists of the following core components: • Tactics, denoting short-term, tactical adversary goals during an attack; • Techniques, describing the means by which adversaries achieve tactical goals; • Sub-techniques, describing more specific means by which adversaries achieve tactical goals at a lower level than techniques; and • Documented adversary usage of techniques, their procedures, and other metadata. My concern is with MITRE's definition of "tactics" as "short-term, tactical adversary goals during an attack," which is oddly recursive. The key word in the tacti...
