Which of the following security protocols is currently considered the most secure for Wi-Fi networks?

Correct option is D

The most secure Wi-Fi protocol currently is WPA3, introduced in 2018 as an improvement over WPA2. WPA3 provides robust encryption mechanisms, such as Simultaneous Authentication of Equals (SAE) for better protection against brute force attacks and enhanced security even when weak passwords are used.
Example:
· WPA3 uses 128-bit encryption for personal networks and 192-bit encryption for enterprise networks, offering superior data protection.
Important Key Points:
1. WPA3 addresses vulnerabilities in WPA2, particularly against dictionary attacks and key reinstallation attacks (KRACK).
2. Simultaneous Authentication of Equals (SAE) replaces the Pre-Shared Key (PSK) mechanism for more secure handshake processes.
3. WPA3 improves security on public Wi-Fi networks with the OWE (Opportunistic Wireless Encryption) feature.
Knowledge Booster:
· WEP: An outdated and insecure protocol using weak encryption keys, making it susceptible to cracking within minutes.
· WPA: Improved over WEP by introducing TKIP (Temporal Key Integrity Protocol), but still vulnerable to certain attacks.
· WPA2: Widely used before WPA3, it uses AES (Advanced Encryption Standard) for secure encryption but is vulnerable to KRACK attacks.
· EAP: A framework used within WPA/WPA2/WPA3 for authentication but is not itself a Wi-Fi security protocol.
