Re: Signature Lookup Confusion

This means generator 120, signature 1, revision 1.  Gen 120 is "HTTP
Inspect preprocessor ( Server )", which is consistent with your alert.

I'm having a bit of a problem fully grasping how to search up rules that
have been fired.....

2013-05-07T10:14:05-07:00 firewall snort[62223]: [120:8:1] (http_inspect)
INVALID CONTENT-LENGTH OR CHUNK SIZE [Classification: Unknown Traffic]
[Priority: 3] {TCP} 209.97.200.53:32459 -> 216.178.47.38:80


Ok so what I understand from the log is that rule 120 fired. Either I need
some caffeine or it's a horrible Tuesday for me to comprehend this, but I'm
just not getting it. The instructions on how to search for the group id and
the sid for some reason are not sticking. Can someone dumb this down for
me....I'm gonna run out and get a pop and hopefully come back to someone
who has awesomely helped me out.


Basically I want to be able to search for explanations on whatever event
happens so I can determine if I need to take action or not.
