Just think of an IDS configured for just raising alerts, but not
resetting / blocking the connections.

Or, a Linux box with IPTables / Snort, and snort just detecting
attacks. IPTables would not block the attacks by default.

If you take a commercial FW such as CheckPoint with SMART Defense
enabled, for instance, it will block all app-level attacks it will
detect by default, so I do not think in this case it would be
expectable to have the firewall ingonring attacks it detects.

Hi

Here is theoretical question:
Can you think on possible scenario in which firewall/ids will detect
that he has been compromised but he won't be able to block it?
Thanks,
