26.4 ADP Commands Overview
Anomaly Detection and Prevention (ADP) protects against anomalies based on violations of protocol
standards (RFCs – Requests for Comments) and abnormal flows such as port scans. This section
introduces ADP, anomaly profiles and applying an ADP profile to a traffic direction.
Traffic Anomalies
Traffic anomaly policies look for abnormal behavior or events such as port scanning, sweeping or
network flooding. They operate at OSI layer-2 and layer-3. Traffic anomaly policies may be updated
when you upload new firmware.
Protocol Anomalies
Protocol anomalies are packets that do not comply with the relevant RFC (Request For Comments).
Protocol anomaly detection includes:
TCP Decoder
UDP Decoder
ICMP Decoder
Protocol anomaly policies may be updated when you upload new firmware.
