IPS
The FortiGate Intrusion Prevention System (IPS) combines signature- and anomaly-
based intrusion detection and prevention with low latency and excellent reliability. The
FortiGate unit can record suspicious traffic in logs, can send alert email to system
administrators, and can log, pass, drop, reset, or clear suspicious packets or
sessions. You can adjust some IPS anomaly thresholds to work best with the normal
traffic on the protected networks. You can also create custom signatures to customize
the FortiGate IPS for diverse network environments.
You can configure the IPS globally and then enable or disable all signatures or all
anomalies in individual firewall protection profiles.
Table 23 describes the IPS settings
and where to configure and access them. To access protection profile IPS options go
to Firewall > Protection Profile, select edit or Create New, and select IPS. See
“Protection profile options” on page 231 .
Protection profile configuration
For information about adding protection profiles to firewall policies, see “To add a
protection profile to a policy” on page 236 .
