Question
A technician is configuring a home network. What is the best encryption protocol for securing Wi-Fi?
A. WEP
B. AES-128
C. WPA3
D. Open network
E. 802.1X
Answer
C. WPA3
Explanation
WPA3 provides the highest level of encryption and security for wireless networks.
WPA3 (Wi-Fi Protected Access 3) is the most advanced and secure wireless encryption protocol currently available for home and enterprise networks. It improves upon previous standards (WEP, WPA, WPA2) by offering stronger encryption, individualized data encryption for each device, and enhanced protection against brute force and offline password-guessing attacks. WPA3 uses Simultaneous Authentication of Equals (SAE) for key exchange, which eliminates vulnerabilities found in WPA2, such as the KRACK attack, and ensures unique encryption keys for every session.
Additional security features include:
- Mandatory use of Protected Management Frames to prevent eavesdropping and forging.
- 128-bit minimum encryption for personal networks and optional 192-bit encryption for enterprise networks.
- Elimination of obsolete protocols, reducing exposure to legacy vulnerabilities.
WPA3 is recommended by industry experts and security organizations as the best choice for wireless network security. If WPA3 is not supported by your devices, WPA2 is the next best alternative, but WEP and WPA should be avoided due to significant security flaws.
WPA3 provides the highest level of wireless security and should be used whenever possible to protect home and business Wi-Fi networks from unauthorized access and modern cyber threats.
