Check: GEN003252

SUSE Linux Enterprise Server v11 for System z STIG: GEN003252 (in versions v1 r12 through v1 r9)

Title

The at.deny file must have mode 0600 or less permissive. (Cat II impact)

Discussion

The "at" daemon control files restrict access to scheduled job manipulation and must be protected. Unauthorized modification of the at.deny file could result in Denial of Service to authorized "at" users or provide unauthorized users with the ability to run "at" jobs.

Check Content

Check the permissions of the file. # ls -lL /etc/at.deny If the file has a mode more permissive than 0600, this is a finding.

Fix Text

Change the mode of the file. # chmod 0600 /etc/at.deny
