CompTIA A+ Core 2 (220-1202)SecurityMedium
A small business is setting up a new wireless network. They want to ensure strong encryption for all data transmitted over the air and require a robust authentication method that uses a pre-shared key, but also supports stronger individual authentication if they decide to upgrade in the future. Which wireless security protocol should they implement?
- AWPA3
- BWPA2
- CWPA
- DWEP
Show answer & explanationAnswer & explanation
Correct answer: A. WPA3
WPA3 is the latest and most secure wireless security protocol. It offers stronger encryption than WPA2, uses Simultaneous Authentication of Equals (SAE) for robust pre-shared key authentication, and is designed with future upgrades to enterprise authentication in mind. WPA3 also provides enhanced privacy in open networks not relevant to this question.
Why the other options are wrong
- B. WPA2 is currently widely used but WPA3 offers stronger security and future-proofing.
- C. WPA is an improvement over WEP but is still considered insecure.
- D. WEP is an outdated and insecure protocol.
WPA3
The latest and most secure wireless security protocol, offering enhanced encryption and authentication methods.
- Uses Simultaneous Authentication of Equals (SAE) for stronger PSK.
- Provides individual data encryption in open Wi-Fi networks (opportunistic wireless encryption).
- More resilient against brute-force attacks compared to WPA2.
Memory trick: Wireless security goes from weak WEP to strong WPA3.
