ISC2 Certified in Cybersecurity (CC)Network SecurityMedium
A network administrator is configuring a new Wi-Fi network for a school and needs to select the strongest encryption protocol available to protect sensitive student data. The network will support modern devices. Which Wi-Fi security standard should be prioritized?
- AWPA
- BWPA2
- CWEP
- DWPA3
Show answer & explanationAnswer & explanation
Correct answer: D. WPA3
WPA3 is the latest and most secure Wi-Fi security standard, offering enhanced encryption, protection against brute-force attacks, and improved privacy compared to its predecessors.
Why the other options are wrong
- A. WPA is an improvement over WEP but has known vulnerabilities and is outdated.
- B. WPA2 is still widely used but has been superseded by WPA3 for stronger security.
- C. WEP is easily crackable and considered highly insecure.
WPA3 (Wi-Fi Protected Access 3)
The latest security protocol for Wi-Fi networks, offering robust encryption and improved protection against common attacks compared to older standards.
- Uses 192-bit cryptographic strength in Enterprise mode.
- Provides 'Simultaneous Authentication of Equals' (SAE) for stronger password-based authentication.
- Offers enhanced privacy in open networks with 'Opportunistic Wireless Encryption' (OWE).
- Protects against offline dictionary attacks.
Memory trick: Remember Wi-Fi security like a ladder: WEP fell, WPA wobbled, WPA2 stood firm, but WPA3 is the top rung.
