Title

The cron.allow file must have mode 0600 or less permissive. (Cat II impact)

Discussion

A readable and/or writable cron.allow file by users other than root could allow potential intruders and malicious users to use the file contents to help discern information, such as who is allowed to execute cron programs, which could be harmful to overall system and network security.

Check Content

Check mode of the cron.allow file. Procedure: # ls -lL /etc/cron.allow If the file has a mode more permissive than 0600, this is a finding.

Fix Text

Change the mode of the cron.allow file to 0600. Procedure: # chmod 0600 /etc/cron.allow
