Re: Pulledpork and sid-msg.map

[Avery Rozar <Avery.Rozar () i-techsupport com>]

Basically I just want rules that result in drop, to have drop in the msg (my sed script does this for me) so when I'm 
searching alerts, or building charts from the alerts I know if the result was a drop, or just alert.

You can use the modify.sid file if you wanted to modify the signature for a rule.. but you want to do it to all of them?

I would probably have something run before you ran pulledpork that changed the rules files; your sed command for 
example, then let pulledpork run off of the existing files ( -n switch, don't have it download new ones).. that way you 
can control the process. I wouldn't change pulledpork.

Is it safe to assume when using pulledpork the msg field in the snort.rules gets pulled into the sid-msg.map for 
barnyard2 to write into the alert?

If so, where in the pulledpork.pl<http://pulledpork.pl> script should I add a shell script to add drop into the msg 
field. I can run this [sed -i '/^drop/s/(msg:"/(msg:"drop - /‘ /etc/snort/rules/snort.rules] in a shell script and adds 
the drop into the msg field, but I need to do this before the sid-msg.map is generated for this to work.

I’ve added the following command in two places with no luck.

system ("sh /opt/scripts/./add_drop_msg.sh”);


At the end of [sub rule_write]

If I put it here it will write drop in the msg on the snort.rules, but not sid-msg.map.


At the beginning of [sub sid_write]

If I put it here it will write drop in the msg on the snort.rules, but not sid-msg.map.
