30.3 Introducing IDP Profiles

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 Section 31.1 on page 513 for information on anomaly detection).
