Configuring Anomaly Detection
Configuring Anomaly Detection
Use the Anomaly Detection policy to configure anomaly detection settings. The Virtual Sensors policy
also contains a setting important for anomaly detection.
This procedure explains the overall configuration of anomaly detection. Before configuring these
settings, read the following topics:
Understanding Anomaly Detection, page 40-1
Worm Viruses, page 40-2
Anomaly Detection Modes, page 40-2
Anomaly Detection Zones, page 40-3
Knowing When to Turn Off Anomaly Detection, page 40-4
Configuring Anomaly Detection Signatures, page 40-4
Step 1 Do one of the following to open the Anomaly Detection policy you want to modify:
(Device view) Select IPS > Anomaly Detection from the Policy selector.
(Policy view) Select IPS > Anomaly Detection from the Policy selector. Select an existing policy
or create a new one.
The Anomaly detection policy includes these tabs:
Operation Settings—Defines the worm timeout and identifies any IP addresses that should be
ignored by anomaly detection.

Scanner
Identified a single scanner over a UDP
protocol in the illegal zone.
13007 1 Illegal UDP
