Question:

As you present your plan for deploying a wireless network to top management, you are asked about the type of wireless security standard you should implement if you prefer not to use enterprise authentication but still want secure user authentication that doesn't rely on a shared password or passphrase. Which one should you choose?

A WPA3.
explanation

WPA3 employs SAE (Simultaneous Authentication of Equals), which is a more secure authentication method that minimizes the risk of brute-force attacks and allows individuals to have unique passwords. In contrast, WPA is not as secure as WPA2, and WEP is the oldest and least secure wireless security protocol available.
SAE does not require a pre-shared key or a centralized authentication server like the one used in WPA2-Enterprise.
With SAE, a peer-to-peer connection is established between devices, and both parties contribute to the creation of a shared secret key. SAE utilizes a technique called dragonfly key exchange, which is a variant of the elliptic curve Diffie-Hellman (ECDH) key exchange protocol.
During the SAE process, both the client and the access point generate a random number, perform a mathematical calculation, and then exchange the results. This process is repeated several times until both sides have enough information to generate the shared secret key.
SAE is designed to protect against offline brute-force attacks by using a password-based key derivation function that derives the encryption key from the password, salt, and other contextual information such as the MAC address of the access point. This contextual information makes it harder for attackers to launch offline brute-force attacks because each access point has a unique MAC address, which adds an additional layer of complexity to the key derivation process.
