=====Profile Applicability=====  
<code>
Level 1 - Server
Level 2 - Workstation 
</code>

=====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.
