An organization plans to increase security controls for devices that connect to its internal network. The additional security control must perform port-based authentication as part of the connection process. Which of the following should the organization implement?
Correct Answer: C
802.1X is the correct answer because it provides port-based network access control. It authenticates devices or users before allowing access through a switch port or wireless access point. In a typical deployment, the supplicant is the endpoint, the authenticator is the switch or access point, and the authentication server is often RADIUS. This allows an organization to prevent unauthorized devices from connecting to the internal network. EDR protects endpoints by detecting and responding to threats, but it does not provide port-based authentication. SASE is a cloud-delivered security architecture for secure access and networking. WPA3 strengthens wireless encryption and authentication, but the phrase "port-based authentication" specifically identifies 802.1X. Therefore, 802.1X best satisfies the requirement.
