Check: GEN003255

HP-UX 11.23 STIG: GEN003255 (in version v1 r8)

Title

The at.deny file must not have an extended ACL. (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 /var/adm/cron/at.deny If the permissions include a "+" the file has an extended ACL, this is a finding.

Fix Text

Remove the optional ACL from the file. # chacl -z /var/adm/cron/at.deny
