Paul,

     I started out in the beginning whining to every ISP I could track down.
You would have to hire a person full time do that if that is what you wanted
to do.  I typically whine if they scan more than a 3 or 4 ports on any one
server at once.  I also whine if they do certain types of scans that a
typical script kiddie wouldn't be running.  You might also want to complain
if you see the same IP hitting your server day after day after day even if
they only do one scan once a day, they may be trying to be inconspicuous,
hoping you will miss them.  Just some of the things to think about.  You
might want to look at something to help manage the logs like Acid or some
other product, it will make the job much easier to spot trends.
     You know your management better than anyone but, the BEST security
measure you can take is knowing what is going on with your network and
keeping a close eye on the logs is one of the best ways to do that.

Hope this helps

Subject: [Snort-users] I'm being attacked, now what?


I wanted to get some feedback from others out there on how they handle
attacks, whether successful or unsuccessful. I see what appears to be
valid
attacks in small numbers from random machines. Occasionally, I see tons of
different attacks coming from ONE machine. Though all attacks are
unsuccessful, when does someone scream to the ISP to tell them to stop
their
client, and when does one just ignore it?

It would obviously be VERY time consuming (and a waste of time) to send
complaints to every ISP. What do people recommend out there....maybe only
send a complaint when attacks from one node become ridiculously large, or
if
they successfully break in?

The logs are nice to have, but I know management will ask what are we
doing
about the attacks we are seeing and what is the time you are spending
maintaining the IDS server doing for the company?

Thanks
