Title

Cron and crontab directories must have mode 0755 or less permissive. (Cat II impact)

Discussion

To protect the integrity of scheduled system jobs and to prevent malicious modification to these jobs, crontab files must be secured.

Check Content

Check the mode of the crontab directory. # ls -ld /var/spool/cron/crontabs If the mode of the crontab directory is more permissive than 0755, this is a finding.

Fix Text

Change the mode of the crontab directory. # chmod 0755 /var/spool/cron/crontabs
