Selah works as a network administrator for Acme Company. Some users report that they keep getting dropped from the network. When Selah checks the logs for the wireless access point (WAP), she finds that a deauthentication packet has been sent to the WAP from the users' IP addresses. What seems to be occurring here?

This is an example of a disassociation attack. The deauthentication packet causes Selah's system to disassociate, and the attacker can then execute a second attack targeting her authentication credentials or other wireless data using an evil twin attack. Misconfiguration won’t cause authenticated users to deauthenticate. Session hijacking involves taking over an authenticated session. Backdoors are built-in methods to circumvent authentication.
