Hmm, that would be harder to achieve because of our network architecture.
And would require lot of network redesigning, that I do see happening in

Step one would be to move them inside the firewall.  That should cut down

Thanks Joel for the response, and sharing the link to submit FPs.

Also, wanted to ask, if you could provide some leads in the direction of
tuning snorts, would be helpful.


Thanks,
Fatema.

believe that 90% of your alerts are false positives, it would probably be
beneficial to report those false positives to the rule writers.

Most of the time almost 90% of the alerts result in false positive, and
