New net-mgmt Ports Category

Today I got my new ports email from FreshPorts and saw a new ports category: net-mgmt. This contains some of my favorite programs, like Argus and fprobe. I don't agree with many of the ports being in this category though. Why are ISIC, NBTScan, and Packit in net-mgmt when Nemesis, NAT, and IPsorc still in net?

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 .

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
