Re: Can Zeek be installed as in-line IPS?

JB's answer was great. I'd only add that I don't think of Zeek as an IDS.
Zeek is a network security monitor. It's designed to describe what's
happening on your network in a mostly neutral way. It's up to the analyst
to use that data for a variety of purposes, one of which could be intrusion
detection. Suricata and Snort are more characteristic of an "IDS" because
they make judgements about what they see, although Suricata has been
integrating ever more NSM functionality by logging DNS, HTTP, etc. as Zeek
does.

Aside from web application firewalls, I think the IPS market is fairly dead
anyway with the ubiquity of encrypted north-south network traffic.

Sincerely,

Richard
