Check Text ( C-43223r3_chk )
Check the root crontab (crontab -l) and the global crontabs in "/etc/crontab", "/etc/cron.d/*" for the presence of an rpm verification command such as:
rpm -qVa | awk '$2!="c" {print $0}'
If no such cron job is found, this is a finding.
If the result of the cron job indicates packages which do not pass verification exist, this is a finding unless the changes were made due to another STIG entry.
Fix Text (F-39293r1_fix)
Add a cron job to run an rpm verification command such as:
rpm -qVa | awk '$2!="c" {print $0}'

For packages which failed verification:
If the package is not necessary for operations, remove it from the system.

If the package is necessary for operations, re-install the package.
