RE: Snort auotmatic email alert.

["Jim Hendrick" <jrhendri () maine rr com>]

Hmmm... At the risk of "making this more complicated" you might consider
"swatch" by Todd Atkins. It allows a bit of flexibility in what gets sent
and how often (i.e. wouldn't send 5000 messages in 1 minute, could send a
"saw this 5000 times in 1 minute" email)

Works off tailing the snort (or any other) log file and uses simple
expressions to determine what action (email, command, etc. ) to run.

Later,
Jim

heh... I agree. Below is what I use for email alerts. It goes through all
/var/log/*snort* directories (if you have more than one instance of snort
running), but you may need to adjust path or filter name. Also, make sure
you have:
  output log_ascii:
in your snort.conf and that you run it with "-l /var/log/snort-something -d"
(application layer dump comes in really handy. Further replace mailsubj with
sendmail or whatever else you use.

I suggest using cron to run this every minute.

Regards,
Frank
