Difficulty: MediumWireless Security and Authentication

A network security administrator is standardizing wireless access controls across corporate headquarters and remote locations. Match each wireless security control or protocol to its primary operational feature.

  • WPA3-PersonalUses Simultaneous Authentication of Equals (SAE) to protect against offline dictionary attacks.
  • WPA3-EnterpriseProvides 192-bit cryptographic strength options for enterprise-grade data protection.
  • 802.1X / RADIUSFacilitates centralized AAA authentication of individual domain accounts using EAP protocols.
  • Captive PortalIntercepts web traffic to require guest user authentication or AUP acceptance prior to granting network access.

Answer

WPA3-Personal matches Simultaneous Authentication of Equals (SAE); WPA3-Enterprise matches 192-bit cryptographic strength options; 802.1X / RADIUS matches centralized AAA authentication via EAP; Captive Portal matches web traffic interception for guest authentication/AUP acceptance.
Each wireless security mechanism is correctly paired to its underlying protocol or operational behavior: WPA3-Personal uses SAE to defend against offline dictionary attacks; WPA3-Enterprise provides optional 192-bit cryptographic mode; 802.1X/RADIUS supplies centralized AAA authentication using EAP; Captive Portal handles guest traffic redirection and policy acceptance.

Step-by-Step Solution

1
Analyze the personal vs enterprise authentication standards
Identify WPA3-Personal as utilizing SAE and WPA3-Enterprise as offering optional 192-bit cryptographic suites.
SAE provides robust protection against password cracking for shared passphrases, while Enterprise mode focuses on high-grade cryptographic suites.
2
Evaluate enterprise central authentication infrastructure
Associate 802.1X / RADIUS with centralized account management using EAP protocols.
802.1X provides port-based access control authenticating individual domain users against a central RADIUS server.
3
Determine guest access and policy enforcement methods
Link Captive Portal to web redirection for guest user authentication and AUP consent.
Captive portals manage guest access by intercepting HTTP/HTTPS traffic until access conditions are fulfilled.
