Check Text (C-215192r991589_chk)
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 Text (F-16388r294028_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.
