Discussion

All systems are vulnerable if terminals are left logged in and unattended. Leaving system terminals unsecure poses a potential security hazard. If the interface is AIXwindows (CDE), use the xlock command to lock the sessions.

Check Content

If AIX CDE (X11) is not used, this is Not Applicable.

Check the system to determine if "X11.apps.clients" is installed: 
# lslpp -L X11.apps.clients

If the "X11.apps.clients" fileset is not installed, this is a finding. 

Check if "xlock" command exists using the following command:
# ls  /usr/bin/X11/xlock

The above command should display the following:
/usr/bin/X11/xlock

If the above command does not show that "/usr/bin/X11/xlock" exists, this is a finding.

Fix Text

Install "X11.apps.clients" fileset from the AIX DVD Volume 1 using the following command (assuming that the DVD is mounted to/dev/cd0):

# installp -aXYgd /dev/cd0 -e /tmp/install.log X11.apps.clients
