Abstract
An access point (AP) in a deployment may be attacked by a rogue AP. The rogue AP may transmit fake beacons that include a fake/incorrect basic service set (BSS) color that does not match the BSS color assigned to/used by the AP under attack. Due to this BSS color mismatch, stations associated to the AP under attack may switch to the fake/incorrect BSS color, and communications between the AP under attack and the stations may be disrupted, and can eventually lead to service denial. Systems and methods are provided for leveraging the BSS color feature to identify when a rogue AP is attacking another AP. Upon detecting an attack, the BSS color feature may be disabled to mitigate the level of service disruption to the AP under attack and the stations associated to that AP.
