Question

Difficulty: Very hardWireless Security and Authentication

Match each wireless authentication protocol or security framework on the left with its correct operational requirement and cryptographic mechanism on the right.

  • EAP-FASTEstablishes a secure tunnel using Protected Access Credentials (PACs) generated and managed by an authentication server, avoiding mandatory PKI certificate deployment.
  • PEAP-MSCHAPv2Encapsulates user credentials inside an encrypted TLS tunnel established using only a server-side digital certificate while authenticating the client via MS-CHAPv2.
  • EAP-TLSEnforces mutual authentication by requiring valid X.509 digital certificates installed on both the RADIUS authentication server and every connecting client endpoint.
  • WPA3-SAEReplaces static pre-shared keys with a dragonfly key exchange mechanism that provides forward secrecy and protects against offline password dictionary attacks.

Answer

EAP-FAST matches with Protected Access Credentials (PACs) without mandatory PKI certificates; PEAP-MSCHAPv2 matches with server-side certificate tunneling user password authentication; EAP-TLS matches with mutual X.509 certificate authentication on both client and server; WPA3-SAE matches with dragonfly key exchange protecting against offline dictionary attacks.
Each protocol is accurately matched to its distinct architecture: EAP-FAST uses PACs in lieu of server certificates; PEAP-MSCHAPv2 uses a single server certificate to encrypt user password authentication; EAP-TLS enforces mutual authentication using digital certificates on both endpoints; WPA3-SAE implements Dragonfly zero-knowledge key exchange for pre-shared key environments.

Step-by-Step Solution

1
Analyze certificate requirements for enterprise EAP protocols
Identify that EAP-TLS mandates client and server digital certificates, PEAP-MSCHAPv2 requires only a server-side certificate, and EAP-FAST utilizes PACs to bypass standard PKI deployment.
Differentiating 802.1X/EAP authentication methods based on PKI complexity is essential for enterprise wireless deployments.
2
Analyze personal/SOHO WPA3 security improvements
Identify WPA3-SAE as the modern replacement for WPA2-PSK that uses the Dragonfly handshake to prevent offline brute-force attacks.
Understanding key exchange security enhancements distinguishes WPA3 personal security mechanisms from enterprise RADIUS-based solutions.
3
Map each authentication term to its corresponding requirement
Correlate EAP-FAST to PACs, PEAP-MSCHAPv2 to server-side certificate password tunneling, EAP-TLS to mutual certificate authentication, and WPA3-SAE to dragonfly key exchange.
Verifies precise conceptual matching across all four wireless security frameworks.
