I used to use www.whitehats.com <http://www.whitehats.com>  to lookup each
occurance, but they don't appear to be online anymore. If you go to
www.snort.org <http://www.snort.org>  and choose the "All the information
about rules you could ever want" option in the left pane, then you can start
looking up EACH alert you receive to get a better understanding. After doing
this for a while you will reach a point where you will know most of the
recurring alerts that appear day to day and will be able to quickly review
alerts each day and pick on out the less common ones and investigate. It
takes a while at first but gets easier.

Subject: [Snort-users] General Snort Help!

Hello, I am very new at the whole Intrusion Detection Process and especially
There is a network administrator here that has installed an IDS utilizing
snort, etc and is responsible for maintaining the system.
I was hired by the Security Administrator to help monitor the alerts on a
daily basis, analyze the data, and help reduce the false positives.
So, I have the easy job, but I'm having major difficulties understanding
what the alerts actually mean and deciphering what is a false positive, true
intrusion, or just an informational alert.  I have read the Snort user
manual, understand how to read the rules, and have found some information on
the alerts, but it is still confusing to me.
Can anyone recommend additional resources that would help me (books, on-line
manuals, or web sites)?
I've read emails from the Snort mailing list and this all seems to make a
lot of sense to everyone else, I'm curious how you all obtained your
knowledge and if there is anything you can share with me!?
I apologize in advance if this is not the correct list for the question.
Any help or advice would be greatly appreciated.
Thank you so much!
