Overview

Finding ID Version Rule ID IA Controls Severity
V-984 GEN003280 SV-45648r2_rule Medium
Description
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 Text ( C-43013r2_chk )
If the “at” package is not installed, this is not applicable.

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