An IDP profile is a set of packet inspection signatures. 

Packet inspection signatures examine packet content for malicious data. Packet 
inspection applies to OSI (Open System Interconnection) layer-4 to layer-7 
contents. You need to subscribe for IDP service in order to be able to download 
new signatures.

In general, packet inspection signatures are created for known attacks while 
anomaly detection looks for abnormal behavior (see 

 for 

information on anomaly detection).

gets larger as the set is enhanced.
