Description

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine.

Suricata 7.0.8 includes options to allow users to configure how to handle TCP urgent data. In IPS mode, you can use a rule such as drop tcp any any -> any any (sid:1; tcp.flags:U*;) to drop all the packets with urgent flag set.
