5.11 Wireless Intrusion Detection System
The Motorola Wireless Intrusion Detection System (WIDS) protects against a wide range of malicious
attacks on the WS2000 Wireless Switch. This feature inspects each packet that is received by the WS2000
and then based on analysis decides if an intrusion is happening on the device.
By default, WIDS is disabled. It can be enabled from the [Network Configuration]-->Wireless-->WIDS
screen.
For WIDS a violation is when excessive numbers of packets of the same type are received.
WIDS keeps track of each packet type that is received and when a threshold value is crossed, raises a
violation alarm. Appropriate action can be performed based on the alerts. WIDS provides alerts when
thresholds are crossed for:
• MUs
•Radio
•Switch
WIDS keeps tracks of these violations:
probe-req - Probe Requests
auth-assoc-req - Authentication Association Requests
deauth-deassoc-req - Deauthentication De-association Requests
auth-fails - Authentication Failures
crypto-replay - Cryptography Replays
802.11-replay - 802.11x Replays
decrypt-fails - Decryption Failures
unassoc-frames - Unassociated Frames
eap-starts - EAP Start Frames
