Context
WLAN services are available in public places, such as banks and airports. Users can connect to the WLANs after associating with corresponding SSIDs. If a rogue AP is deployed and provides spoofing SSIDs similar to authorized SSIDs, the users may be misled and connect to the rogue AP, which brings security risks. To address this problem, configure a fuzzy matching rule to identify spoofing SSIDs. The device compares a detected SSID with the matching rule. If the SSID matches the rule, the SSID is considered a spoofing SSID. The AP using the spoofing SSID is a rogue AP. The device then take countermeasures against the rogue AP, forcing users to disconnect from the AP.
Procedure
- Create an SSID profile.
- Set parameters for creating a WIDS spoof SSID profile. Table 1 describes the parameters for modifying an SSID profile.
Table 1 Parameters for creating a WIDS spoof SSID profile Parameter
Description
WIDS Spoof SSID Profile
Name of the WIDS spoof SSID profile, which cannot be modified.
Rule for identifying spoofing SSIDs
Regular expression of an SSID. After this parameter is set, click
. If a detected SSID matches the regular expression, the SSID is considered a spoofing SSID. Repeat the preceding steps
to add multiple rules for identifying spoofing SSIDs. Click 
to delete the selected rule for identifying spoofing SSIDs.
