[Snort-users] Basic questions about snort

Hi Jason.

I'm using snort with "Guardian.pl" on our firewall. Snort is logging to
a remote DB (MySQL) and guardian is making deny rules for the attacking
hosts. Also I use "girr.sh" to delete these rules (and also some false
positives) every 24 hours.
I'm using ACID on the DB to watch my alerts and also informations.
You can use "logsnorter", which reads syslog at realtime and puts the
alerts from CISCO-ACL violations and IPCHAONS to the same DB, so I can
watch them all together.
I mean, my cisco's and other servers including firewalls are logging to
one central server.
I will try to make some script, generating some report of blocked hosts,
current alerts and so on to notify me by mail or pager. And I will have
a look at "snorticus" scripts.
This setup works well for me.

Hope this helps.
