Zorluk: OrtaWireless Security and Authentication

A system administrator is updating the corporate wireless security baseline and guest network policies. Match each wireless security protocol or feature on the left with its correct operational description or technical requirement on the right.

  • RADIUS ServerA centralized AAA backend server that verifies individual user credentials against an identity directory.
  • WPA3 SAEA key exchange protocol that replaces PSK to prevent offline dictionary attacks on wireless handshakes.
  • Captive PortalA web interface that intercepts initial network traffic to require user login or agreement to terms.
  • 802.1XAn IEEE framework for port-based network access control that encapsulates EAP communications.

Cevap

RADIUS Server pairs with the centralized AAA backend server; WPA3 SAE pairs with the key exchange protocol protecting against offline dictionary attacks; Captive Portal pairs with the web interface requiring user agreement or login; and 802.1X pairs with the IEEE port-based network access control framework.
Each feature is correctly matched according to standard CompTIA A+ definitions: RADIUS performs backend AAA authentication, WPA3 SAE secures personal wireless handshakes against brute-force/dictionary attacks, Captive Portals manage guest web access enforcement, and 802.1X provides port-based authentication architecture.

Adım Adım Çözüm

1
Analyze backend authentication services in enterprise environments.
Pair RADIUS Server with the centralized AAA backend definition.
RADIUS handles authentication requests sent from wireless authenticators (access points).
2
Evaluate WPA3 enhancements to personal security.
Pair WPA3 SAE with protection against offline dictionary attacks.
SAE utilizes Dragonfly handshake mechanism to ensure forward secrecy and brute-force resistance.
3
Identify web redirection mechanisms for guest access control.
Pair Captive Portal with the web interface intercepting network traffic.
Captive portals restrict network browsing until the user completes the browser landing page requirements.
4
Identify port-based access standards.
Pair 802.1X with the IEEE port-based access control framework.
802.1X defines port status (authorized/unauthorized) and encapsulates EAP packets across local media.
