An organization is making enhancements to its wireless network to bolster security against emerging threats. Which feature should be implemented to provide robust defenses against attempts to compromise the handshake process used during wireless authentication?
Introduce a protocol that maximizes data throughput for high-density wireless environments.
Implement Protected Management Frames (PMF) to prevent deauthentication attacks.
Deploy an 802.1X solution using a RADIUS server.
Upgrade to a protocol that replaces the Pre-Shared Key (PSK) handshake with Simultaneous Authentication of Equals (SAE).
The WPA3 wireless security protocol introduces a more secure handshake process known as Simultaneous Authentication of Equals (SAE). This mechanism replaces the vulnerable 4-way handshake from WPA2-Personal (which uses a Pre-Shared Key) and provides protection against offline brute-force attacks. SAE also provides forward secrecy, meaning a compromised password cannot be used to decrypt previously captured traffic. While Protected Management Frames (PMF) are an important security feature for preventing deauthentication attacks, they do not secure the authentication handshake itself. An 802.1X/RADIUS solution represents a move to an enterprise authentication model, which is a different security paradigm than hardening a PSK-based system. Maximizing data throughput is a performance goal related to standards like Wi-Fi 6, not a handshake security feature.
