Description
This security measure helps limit the effects of denial-of-service attacks by employing antisession hijacking security safeguards. Session hijacking, also called cookie hijacking, is the exploitation of a valid computer session to gain unauthorized access to an application. The attacker steals (or hijacks) the cookies from a valid user and attempts to use them for authentication.
