Description
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 logoff messages as final messages prior to terminating sessions.
If the Mainframe Product has no logon capability, this requirement is not applicable.
If the Mainframe Product does not provide a logout capability for user initiated communication sessions, this is a finding.
Examine the Mainframe Product configuration settings to determine whether a user can logoff. If the configurations are not properly set, this is a finding.
