Check Text ( C-28474r1_chk )
Check the cron.allow and cron.deny files for the system. # more /etc/cron.allow # more /etc/cron.deny If a default system account (such as bin, sys, adm, or others, traditionally UID less than 500) is listed in the cron.allow file, or not listed in the cron.deny file and if no cron.allow file exists, this is a finding.

Fix Text (F-31374r1_fix)
Remove default system accounts (such as bin, sys, adm, or others, traditionally UID less than 500) from the cron.allow file if it exists, or add those accounts to the cron.deny file.
