A company is setting up a secure wireless network for its employees. To comply with security best practices, they need to select the strongest available encryption protocol for Wi-Fi. Which of the following Wi-Fi security protocols should they implement?
- AWEP
- BWPA2
- CWPA
- DWPA3
Show answer & explanationAnswer & explanation
Correct answer: D. WPA3
WPA3 (Wi-Fi Protected Access 3) is the latest and most secure Wi-Fi security protocol, offering significant improvements over WPA2, including more robust encryption, enhanced protection against brute-force attacks, and individualized data encryption in public Wi-Fi networks (Wi-Fi Enhanced Open).
Why the other options are wrong
- A. WEP (Wired Equivalent Privacy) is outdated and easily crackable, offering very weak security.
- B. WPA2 (Wi-Fi Protected Access 2) has been the standard for a long time and is still widely used, but WPA3 offers stronger security and addresses some of WPA2's weaknesses.
- C. WPA (Wi-Fi Protected Access) was an improvement over WEP but has known vulnerabilities and is no longer considered secure enough for enterprise use.
WPA3 (Wi-Fi Protected Access 3)
The latest and most secure encryption protocol for wireless networks, providing enhanced security features over its predecessors.
- Uses 128-bit or 192-bit cryptographic algorithms.
- Provides stronger protection against brute-force attacks (SAE).
- Offers individualized data encryption in public Wi-Fi (Enhanced Open).
Memory trick: WEP, WPA, WPA2, WPA3: Stronger with each iteration.
