InformationSquid is a standard proxy server used in many distributions and environments.
If there is no need for a proxy server, it is recommended that the squid proxy be deleted to reduce the potential attack surface.
SolutionRun the following command to disable squid:
# systemctl --now disable squid
Additional methods of disabling a service exist. Consult your distribution documentation for appropriate methods.
On some distributions the squid service is known as squid3, not squid. Several HTTP proxy servers exist. These and other services should be checked.
