 +=====Description=====
 +Wireless networking is used when wired networks are unavailable. Ubuntu 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.
 +
 +=====Audit===== ​
 +Run the following command to determine wireless interfaces on the system::
 +<​Code:​bash>​
 +# iwconfig
 +</​Code>​
 +
 +Run the following command and verify wireless interfaces are active:
 +<​Code:​bash>​
 +# ip link show up
 +</​Code>​
 +
 +=====Remediation===== ​
 +Run the following command to disable any wireless interfaces:
 +<​Code:​bash>​
 +# ip link set <​interface>​ down
 +</​Code>​
 +Disable any wireless interfaces in your network configuration.
 +
 +=====Impact===== ​
 +Many if not all laptop workstations and some desktop workstations will connect via wireless requiring these interfaces be enabled.
