The freeradius package should be removed if not in use.
Is this system a RADIUS server? If not, remove the package.
The freeradius package can be removed with the following command:
$ sudo yum erase freeradius
The freeradius RPM is not installed by default on a Red Hat Enterprise Linux 7
system. It is needed only by the RADIUS servers, not by the
clients which use RADIUS for authentication. If the system is not
intended for use as a RADIUS Server it should be removed.
