The intrusion-detection-system (IDS) signature engine on controllers and on the Cisco WCS automatically eliminates duplicate alerts for rogue access points, rogue clients, and IDS signatures that previously occurred when two or more access points detected the same attacker. Now instead of one IDS alert from each detecting access point, a single alert is generated for the attack.

Intrusion detection, location, and containment preserve the integrity of wireless networks and sensitive corporate information. When an associated client sends malicious traffic, a Cisco wired IDS device detects the attack and sends shun requests to Cisco Wireless LAN Controllers, which then disassociate the client device.
