Description
To centralize the management of privileged account crontabs, of the default system accounts, only root may have a crontab.
ℹ️ Check
Check the "cron.allow" and "cron.deny" files for the system using commands: # more /var/adm/cron/cron.allow # more /var/adm/cron/cron.deny If the "cron.allow" file exists and is empty, this is a finding. If a default system account (such as bin, sys, adm, or lpd) is listed in the "cron.allow" file, or not listed in the "cron.deny" file, this is a finding.
✔️ Fix
Remove default system accounts (such as bin, sys, adm, or lpd) from the "cron.allow" file, or add those accounts to the "cron.deny" file.
