Description
Leaving a user’s application session established for an indefinite period of time increases the risk of session hijacking. Session termination terminates an individual user's logical application session after 15 minutes of application inactivity at which time the user must re-authenticate and a new session must be established if the user desires to continue work in the application.

Ask the application representative to demonstrate the configuration setting where the idle time out value is defined. Alternatively, logon with a regular application user account and let the session sit idle for 15 minutes. Attempt to access the application after 15 minutes of inactivity. If the configuration setting is not set to time out user sessions after 15 minutes of inactivity, or if the regular user session used for testing does not time out after 15 minutes of inactivity, this is a finding.
