To suppress certain snort and ET signatures since initially there a bunch of False Positives.
I prefer having different Suppress lists for each interface.
Navigate to Services → Suricata → Suppress.
Navigate to Services → Suricata → Suppress.
Navigate to Services → Suricata → Suppress.
Navigate to Services → Suricata → Suppress.
Navigate to Services → Suricata → Suppress.
Return to Install Suricata or continue to Have Suricata Monitor the WAN Interface.
ALERT: DO NOT CREATE A PASS LIST!!!
At Services → Suricata → Pass List.
Realistically, about the only time that you should require a Passlist is if you are running a honeypot host and you actually want bad stuff to find its way to that host.
In that situation, a passlist makes sense.
For about any other case, it does not.
Use custom PASS rules instead if you really need passlist functionality.
