Which of the following is a way to secure a wireless network?

• A. Use public Wi-Fi
• B. Disable all encryption
• C. Use WEP encryption
• D. Use WPA3 encryption

Answer: (D)

Using WPA3 encryption is a highly effective way to secure a wireless network. WPA3, or Wi-Fi Protected Access 3, is the latest security protocol designed to protect wireless networks against common threats. It offers several improvements over its predecessors, including stronger encryption methods and enhanced protection for networks, especially open networks that lack a password. WPA3 employs a more robust password-based authentication mechanism known as Simultaneous Authentication of Equals (SAE), which helps to prevent dictionary attacks where an attacker tries numerous password combinations. Additionally, WPA3 supports forward secrecy, meaning that even if a password is compromised in the future, past communications remain secure. The other options present less secure or unsafe practices. For example, using public Wi-Fi often exposes users to numerous risks, such as man-in-the-middle attacks and eavesdropping. Disabling all encryption leaves a wireless network vulnerable to unauthorized access and attacks, while relying on WEP encryption is outdated and insecure, as it contains known vulnerabilities that can be easily exploited by attackers.
