The Centrality of Red Teaming

In my last post I described how a Red Team can improve defense. I wanted to expand on the idea briefly.

First, I believe the modern enterprise is too complex for any individual or group to thoroughly understand how it can be compromised. There are so many links in the chain that even knowing they exist, let alone how they connect, can be impossible.

To flip that on its end, in a complementary way, the modern enterprise is too complex for any individual or group to thoroughly understand how its defenses can fail. The fact that vendors exist to reduce firewall rule sets down to something intelligible by mere mortals is a testament to the apocalyptic fail exhibited by digital defenses.

Furthermore, it is highly likely that hardly anyone cares about attack models until they have been demonstrated. We seen this repeatedly with respect to software vulnerabilities. It can be difficult for someone to take a flaw seriously until a proof of concept is shown to exploit a victim. L0pht's motto "Making the theoretical practical since 1992" is a perfect summarization of this phenomenon.

So why mention Red Teams? They are central to digital defense because Red Teams transform theoretical intrusion scenarios into reality in a controlled and responsible manner. It is much more realistic to use your incident detection and response teams to know what adversaries are actually doing. However, if you want to be more proactive, you should deploy your Red Team to find and connect those links in the chain that result in a digital disaster.

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...
