Details
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.
