Chapter 15 Unified Threat Management for FortiOS 5.0 : Intrusion protection
  
Intrusion protection
The FortiGate Intrusion Protection system combines signature detection and prevention with low latency and excellent reliability. With intrusion protection, you can create multiple IPS sensors, each containing a complete configuration based on signatures. Then, you can apply any IPS sensor to any security policy.
This section describes how to configure the FortiGate Intrusion Protection settings.
If you enable virtual domains (VDOMs) on the FortiGate unit, intrusion protection is configured separately for each virtual domain.
The following topics are included:
IPS concepts
Enable IPS scanning
Configure IPS options
Enable IPS packet logging
