Check: GEN003280

Solaris 9 X86 STIG: GEN003280 (in version v1 r9)

Title

Access to the at utility must be controlled via the at.allow and/or at.deny file(s). (Cat II impact)

Discussion

The at facility selectively allows users to execute jobs at deferred times. It is usually used for one-time jobs. The at.allow file selectively allows access to the at facility. If there is no at.allow file, there is no ready documentation of who is allowed to submit at jobs.

Check Content

Check for the existence of at.allow and at.deny files. # ls -lL /etc/cron.d/at.allow # ls -lL /etc/cron.d/at.deny If neither file exists, this is a finding.

Fix Text

Create at.allow and/or at.deny files containing appropriate lists of users to be allowed or denied access to the "at" daemon.
