Wireless Networking
1 Rule
Wireless networking, such as 802.11 (WiFi) and Bluetooth, can present a security risk to sensitive or classified systems and networks. Wireless networking hardware is much more likely to be included in laptop or portable systems than in desktops or servers.
Removal of hardware provides the greatest assurance that the wireless capability remains disabled. Acquisition policies often include provisions to prevent the purchase of equipment that will be used in sensitive spaces and includes wireless capabilities. If it is impractical to remove the wireless hardware, and policy permits the device to enter sensitive spaces as long as wireless is disabled, efforts should instead focus on disabling wireless capability via software.
Disable Wireless Through Software Configuration
1 Rule
If it is impossible to remove the wireless hardware from the device in question, disable as much of it as possible through software. The following methods can disable software support for wireless networking, but note that these methods do not prevent malicious software or careless users from re-activating the devices.
Deactivate Wireless Network Interfaces
Medium Severity
Deactivating wireless network interfaces should prevent normal usage of the wireless capability.
Configure the system to disable all wireless network interfaces with the following command:
$ sudo nmcli radio all off
