What is the difference between, AP impersonation, AP spoofing and Valid-SSID misuse? 


In AP Impersonation, the attacker AP assumes the same BSSID and ESSID of a valid AP. 

In AP Spoofing, an attacker assumes the BSSID of the valid AP and the ESSID can be any (ESSID can be seen in beacon or probe response). 

In valid-ssid-misuse, an attacker AP assumes the ESSID of the valid AP and the BSSID should be a non-valid Aruba BSSID, i.e, a BSSID that is not being used by any Aruba APs in the cluster. 

Below are the example security logs that can be seen when such attacks are detected.

I think there is a typo error in the Introduction. As per logs you have shared, for AP impersination, both BSSID and ESSID should match. but in AP impersination line, BSSID didn't match. In AP spoofing logs, these BSSID and ESSID matched.


Please correct me if i am wrong!
