Title

The Central Log Server must provide a logout capability for user initiated communication session. (Cat II impact)

Discussion

If a user cannot explicitly end an application 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, databases, and password-protected websites/web-based services. However, for some types of interactive sessions including, for example, file transfer protocol (FTP) sessions, information systems typically send logout messages as final messages prior to terminating sessions.

Check Content

Fix Text
