Discussion

To protect the integrity of scheduled system jobs and to prevent malicious modification to these jobs, crontab files must be secured. ACLs on crontab files may provide unauthorized access to the files.

Check Content

Check the permissions of the crontab files. # ls -D /var/spool/cron/crontabs/ If any file has an extended ACL, this is a finding.

Fix Text

Remove the extended ACL from the file. # chmod A- [crontab file]
