| 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 those operating systems that control wireless devices. Satisfies: SRG-OS-000299-GPOS-00117, SRG-OS-000300-GPOS-00118, SRG-OS-000481-GPOS-00481 | ||||

Check Text (C-252956r991568_chk)
Verify there are no wireless interfaces configured on the system with the following command:
Note: This requirement is Not Applicable for systems that do not have physical wireless network radios.
$ sudo nmcli device status
DEVICE TYPE STATE CONNECTION
virbr0 bridge connected virbr0
wlp7s0 wifi connected wifiSSID
enp6s0 ethernet disconnected --
p2p-dev-wlp7s0 wifi-p2p disconnected --
lo loopback unmanaged --
virbr0-nic tun unmanaged --
If a wireless interface is configured and has not been documented and approved by the Information System Security Officer (ISSO), this is a finding.
Fix Text (F-56359r824191_fix)
Configure the system to disable all wireless network interfaces with the following command:
$ sudo nmcli radio all off
