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:
$ apt-get remove freeradiusThe freeradius RPM is not installed by default on a Ubuntu 24.04 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.
Unnecessary packages should not be installed to decrease the attack surface of the system. While this software is clearly essential on a RADIUS server, it is not necessary on typical desktop or workstation systems.
