34.3 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
Chapter 35 on page 641 for
information on anomaly detection).
