Chapter 1 What’s New for FortiOS 5.0 : Wireless : Wireless IDS
  
Wireless IDS
FortiGate wireless IDS monitors wireless traffic for a wide range of security threats by detecting and reporting on possible intrusion attempts. When an attack is detected, the FortiGate unit records a log message.
You can create a WIDS profile to enable the following types of intrusion detection among others:
Unauthorized Device Detection
Rogue/Interfering AP Detection
Adhoc Network Detection and Containment
Wireless Bridge Detection
Misconfigured AP Detection
Weak WEP Detection
Multi Tenancy Protection
MAC OUI Checking
You can enable wireless IDS by going to WiFi Controller > WiFi Network > Custom AP Profiles and editing an access point profile or creating a new one.
Inside the profile, set WIDS Profile to the name of a wireless IDS profile to apply wireless IDS protection to the access points that uses the profile. FortiGate units include a default wireless IDS profile. You can customize this profile or create additional profiles by going to WiFi Controller > WiFi Network > WIDS Profiles.
