CompTIA A+ Core 2 (220-1202)SecurityMedium
A small business is setting up a new wireless network. They want to ensure strong encryption and use the latest security protocols available for Wi-Fi. All new access points and client devices support the most recent standards. Which wireless security protocol should the administrator configure to meet these requirements?
- AWPA
- BWPA3
- CWEP
- DWPA2
Show answer & explanationAnswer & explanation
Correct answer: B. WPA3
WPA3 is the latest and most secure wireless security protocol, offering enhanced encryption (SAE for personal, 192-bit for enterprise) and protection against dictionary attacks, making it the best choice for new installations requiring strong security.
Why the other options are wrong
- A. WPA was an improvement over WEP but has known vulnerabilities and is outdated.
- C. WEP is highly insecure and easily cracked; it should never be used.
- D. WPA2 is currently widely used and considered secure for most applications, but WPA3 offers further enhancements and is the latest standard.
WPA3
Wi-Fi Protected Access 3, the latest security standard for wireless networks, offering stronger encryption and improved authentication over its predecessors.
- Introduced in 2018 as a replacement for WPA2.
- Uses Simultaneous Authentication of Equals (SAE) for personal mode.
- Provides enhanced protection against dictionary attacks and forward secrecy.
Memory trick: WEP is weak, WPA is better, WPA2 is good, WPA3 is best.
