Description
Allowing devices and users to connect to or from the system without first authenticating them allows untrusted access and can lead to a compromise or attack. Since wireless communications can be intercepted, it is necessary to use encryption to protect the confidentiality of information in transit. 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. Satisfies: SRG-OS-000299-GPOS-00117, SRG-OS-000300-GPOS-00118, SRG-OS-000379-GPOS-00164
