| When “Ask to Join Networks” is set to on, the user is alerted whenever they are in the vicinity of a Wi-Fi hot spot and could be tempted to connect to an unauthorized public hotspot, which could be managed by a hacker. Although the risk of exposing sensitive DoD data is low, setting this configuration as specified is a security best practice. |
