Information

Wireless networking is used when wired networks are unavailable. CentOS Linux contains a wireless tool kit to allow system administrators to configure and use wireless networks.

Rationale:

If wireless is not to be used, wireless devices can be disabled to reduce the potential attack surface.

Impact:

Many if not all laptop workstations and some desktop workstations will connect via wireless requiring these interfaces be enabled.

Solution

Run the following command to disable any wireless interfaces:

# nmcli radio all off

Disable any wireless interfaces in your network configuration.
