Description
Without strong mutual authentication a mobile device may connect to an unauthorized network. In many cases, the user may falsely believe that the device is connected to an authorized network and then provide authentication credentials and other sensitive information. EAP-TLS is strong mutual authentication leveraging a public key infrastructure. Its use greatly mitigates risk associated with authentication transactions.

Navigate to "Options -> Wi-Fi -> Saved Networks" and select a Wi-Fi profile used to connect to DoD WLAN. Ensure "Security Type" is set to "WPA Enterprise" or "WPA2 Enterprise" and "Security Sub Type" (EAP security method) is set to "TLS". These options should be greyed out. Otherwise, this is a finding.
