Title
The cron.allow file must have mode 0600 or less permissive. (Cat II impact)
Discussion
A cron.allow file that is readable and/or writable by 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.d/cron.allow If either 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.d/cron.allow
