Description
If a user cannot explicitly end an operating system session, the session may remain open and be exploited by an attacker; this is referred to as a zombie session. Information resources to which users gain access via authentication include, for example, local workstations and remote services. For some types of interactive sessions, including, for example, remote logon, information systems typically send logoff messages as final messages prior to terminating sessions.
