[Snort-users] Help tuning snort for performance.

Well, the issue with that is, the end user is the one responsible for
turning on/off rules. We leave it to them to turn them on or off b/c if
I turn one off and they get attacked and there was no event recorded,
I'm the one on the hook. So, we place the responsibility on them to turn
on or off the rules. We will go through and turn off major false
positives that we see, like the bare-byte unicode alerts.  So, with that
being said, it's probably a poorly tuned rule set. 

 

Does that make any sense? I know to me, it's a catch-22. 

 

Thanks,

Andy

I'm not the best-qualified to speak to the issue of frag tuning, but
given such a high dropped-packet rate, I figured I would raise another
possibility that I can discuss intelligently: how well-tuned is your
rule set? If you've got a whole bunch of unnecessary rules, turning them
off could make the rest of your tuning needs basically moot.
