IEEE 802.1 X is a security feature that

A) Applies end-to-end encryption between the camera and the server over the internet, ensuring that other users on the network cannot eavesdrop on the surveillance video.
B) Only gives approved devices access to the network, making it impossible to disconnect a camera and connect other equipment to eavesdrop on the network.
C) Disables port forwarding, making it impossible for users outside the local network to get access to the surveillance video.
D) Uses a cryptographic signature to ensure the integrity of the address tables used by the router, making it impossible for malicious users to redirect the surveillance video to unauthorized recipients.
