nuqneH,

Though i think people who buy Checkpoint stuff are somehow non-representative
(i think if one tried that with, say, Cyberguard, we'd see completely
different picture) the results are still scary. Damn scary. That means 80%
firewalls could be thrown off with no further harm to security.

Here's a little tidbit that's about 4 years old now, but ponder it and ask
yourself if the IDS is where people *should* be spending their time:

Approximately 74% of firewalls are either misconfigured or not configured
to block attacks they're capable of blocking in normal operation.
