The anacron subsystem
The anacron subsystem is designed to provide cron functionality for machines which may be shut down during the normal times that system cron jobs run, frequently in the middle of the night. Laptops and workstations which are shut down at night should keep anacron enabled, so that standard system cron jobs will run when the machine boots.
However, on machines which do not need this additional functionality, anacron represents another piece of privileged software which could contain vulnerabilities. Therefore, it should be removed when possible to reduce system risk.
Disable anacron if Possible
Is this a machine which is designed to run all the time, such as a server or a workstation which is left on at night? If so:
# yum erase anacron
