Answer: D
An IDS has a large database of attack signatures, which is
used to ward off attacks. Packet filter and stateful
inspection are types of firewalls. A firewall is a fence
around a network designed to block certain types of
communications routed or passing through specific ports. It
is not designed to discover someone bypassing or going under
the firewall.
