Traffic Talk 7 Posted

I just noticed that my 7th edition of Traffic Talk, titled How to deploy NetFlow v5 and v9 probes and analyzers, was posted on 28 September. I submitted it back in mid-August but it's on the Web now.

On a related note, I am tech editing a forthcoming book on NetFlow by Michael Lucas titled Network Flow Analysis. Michael is probably my favorite technical author, so keep an eye open for his book in May 2010.

Richard,

Have you ever looked at Luca Deri's (of ntop fame) nprobe solution? This was the first product I have been able to use to produce intra-VLAN traffic netflow data.

Hi Stefan,

Nice to hear from you. I have heard of Nprobe but never used it.

Do you have experience with scaling open source netflow tools? Even in my decidedly medium-sized environment (only a few hundred interfaces monitored by netflow), it generates a ton of data that my low-end commercial tools have trouble dealing with. I'm wondering if open source tools would scale better.

Zeek in Action Videos

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

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...
