Question
Which wireless encryption protocol is most secure and should be used whenever possible?
A. WEP
B. WPA
C. WPA2
D. WPA3
E. TKIP
Answer
D. WPA3
Explanation
WPA3 is the latest wireless encryption standard, offering improved security over WPA2.
The most secure wireless encryption protocol, which should be used whenever possible, is WPA3.
WPA3 (Wi-Fi Protected Access 3) is the latest wireless security standard, introduced to address vulnerabilities in previous protocols and provide stronger protection for both personal and enterprise networks.
WPA3 uses the Advanced Encryption Standard (AES) in Galois/Counter Mode (GCM), which is more robust than the AES-CCMP used in WPA2, offering enhanced encryption strength and data confidentiality.
It replaces the pre-shared key (PSK) authentication method with Simultaneous Authentication of Equals (SAE), also known as the Dragonfly protocol. SAE provides stronger protection against offline dictionary attacks and password guessing, and ensures a unique key for each session.
WPA3 also enforces Protected Management Frames (PMF), mitigates key reinstallation attacks (such as KRACK), and supports forward secrecy, so past sessions remain secure even if a password is later compromised.
While WPA2 remains widely used and is still considered secure, WPA3 is recommended for all new deployments and whenever device compatibility allows, as it provides the highest available level of wireless security.
WPA3 is the most secure wireless encryption protocol available, offering advanced encryption, improved authentication, and enhanced protection against modern wireless threats.
