Intrusion Detection Systems (IDS) are pattern based inspection systems most likely
setup on top of a Firewall.
They inspect network traffic as it comes realtime to your
network and watches out for known patterns. Once a pattern is classified as an attack,
the system alarms the Administrator of an potential break in attempt and hands over
to the IPS. Intrusion Prevention is just another form of combining IDS with firewalls
in oder to stop an attacker from entering the network.
