What security feature added in WPA3 enhances the protection of control messages exchanged between wireless devices?

Protected Management Frames (PMF) is a security feature introduced in WPA3 that significantly enhances the protection of control messages exchanged between wireless devices. PMF provides an additional layer of security by ensuring that management frames, which are critical for maintaining communications on a Wi-Fi network, are encrypted and authenticated. This is particularly important because management frames can be vulnerable to eavesdropping and spoofing attacks.

By implementing PMF, WPA3 helps to safeguard against potential attacks that target these frames, such as de-authentication attacks, where an attacker could disrupt the connection by sending forged frames. PMF ensures that even if an attacker attempts to send malicious frames, they can't do so without proper encryption and validation, thereby enhancing the overall integrity and security of wireless communications.

The other options, while related to wireless security in different contexts, do not specifically address the enhancement of control message protection like PMF does. MAC Address Filtering pertains to restricting devices from connecting based on their hardware addresses, SSID Broadcast involves the visibility of the network name, and Forward Secrecy relates more to encryption keys used in secure communications rather than specifically focusing on control message protection.
