NixOS must protect wireless access to the system using authentication of users and/or devices.

| Description | ||||
| Allowing devices and users to connect to the system without first authenticating them allows untrusted access and can lead to a compromise or attack. Wireless technologies include, for example, microwave, packet radio (UHF/VHF), 802.11x, and Bluetooth. Wireless networks use authentication protocols (e.g., EAP/TLS, PEAP), which provide credential protection and mutual authentication. This requirement applies to operating systems that control wireless devices. | ||||

Verify NixOS disables Bluetooth adapters by running the following command:
$ grep -R hardware.bluetooth /etc/nixos/
/etc/nixos/configuration.nix:hardware.bluetooth.enable = false;
If "hardware.bluetooth.enable", does not equal false, is missing, or is commented out, this is a finding.
Fix Text (F-71974r1039328_fix)
Configure /etc/nixos/configuration.nix to disable Bluetooth adapters by adding the following configuration settings:
hardware.bluetooth.enable = false;
Rebuild the system with the following command:
$ sudo nixos-rebuild switch
