I would also recommend to take a look on Envision from Network Intelligence. It
is similar to Cisco CS-MARS (ex Protego), but a
lot more devices and applications are supported.

Take a look at a good SIM product, like CS-MARS from Cisco Systems.
This correlates IPS/IDS events with firewall and other network device logs, and
also with vulnerability assessment tools (including NESSUS built-in). This
correlation is again correlated with network topology information, and
automatically tunes your events for you.
In addition, there is a wealth of reports and query capabilities, as well as a
lot of options for manually creating rules and doing further tuning.
Even though it is from Cisco, it works with most IDS/IPS and firewall products,
not just Cisco.

Subject: Tuning false positives
My company is testing a few intrusion detection & prevention products.
On the first few hours/days after deployment the machines alert on ten of
thousands of events, which is way too much for us to ever go through, most of
which are false alarms.
The vendor's solution is tuning the systems, which means shutting down
signatures, detection mechanisms, omitting defragmentation tests and so on.
These tunings do reduce dramatically the number of alerts, but it seems most of
the detection capabilities have been shut off too, so things are nice and quite
but we've no idea what's really going on in our network apart from catching the
trivial threats such as old worms, which don't get false alarms.
Has anyone encountered this situation? Anyone got a solution?
Thanks
Sam
