Discussion

Terminating an idle session within a short time period reduces the window of opportunity for unauthorized personnel to take control of a management session enabled on the console or console port that has been left unattended. In addition, quickly terminating an idle session will also free up resources committed by the managed network element. Terminating network connections associated with communications sessions includes, for example, de-allocating associated TCP/IP address/port pairs at the operating system level, and de-allocating networking assignments at the application level if multiple application sessions are using a single operating system-level network connection. This does not mean that SLES for vRealize terminates all sessions or network access; it only ends the inactive session and releases the resources associated with that session.

Check Content

Check for the existence of the "/etc/profile.d/tmout.sh" file:

# ls -al /etc/profile.d/tmout.sh

Check for the presence of the "TMOUT" variable:

# grep TMOUT /etc/profile.d/tmout.sh

The value of "TMOUT" should be set to "900" seconds (15 minutes).

If the file does not exist, or the "TMOUT" variable is not set to "900", this is a finding.
