Difficulty: MediumWireless Security Standards and Encryption Protocols

A security analyst is reconfiguring the wireless network for a regional medical center's mobile workstation carts to meet stringent health data protection standards. The organization mandates upgrading to WPA3-Enterprise 192-bit mode. Which of the following requirements must be implemented to achieve this configuration? (Select TWO.)

  1. 802.1X authentication integrated with a RADIUS server supporting EAP-TLSAnswer
  2. GCMP-256 (Galois/Counter Mode Protocol) cipher suite for data payload encryptionAnswer
  3. C
    Simultaneous Authentication of Equals (SAE) key exchange mechanism using a shared passphrase
  4. D
    TACACS+ server integration for wireless client frame encryption and key distribution

Answer

The configuration requires implementing 802.1X authentication with RADIUS EAP-TLS and configuring the GCMP-256 encryption cipher suite.
WPA3-Enterprise 192-bit mode provides maximum security for enterprise wireless networks. It mandates 802.1X RADIUS authentication using EAP-TLS with enterprise PKI certificates, alongside GCMP-256 (Galois/Counter Mode Protocol) for payload encryption.

Step-by-Step Solution

1
Identify the authentication requirements for WPA3-Enterprise 192-bit mode.
WPA3-Enterprise requires centralized authentication via an 802.1X RADIUS architecture, with 192-bit mode specifically mandating EAP-TLS.
Centralized credential verification and mutual certificate authentication prevent unauthorized network access and rogue access point association.
2
Identify the cryptographic encryption cipher suite for 192-bit mode.
WPA3-Enterprise 192-bit mode replaces standard 128-bit ciphers with GCMP-256.
GCMP-256 provides higher-grade 256-bit Galois/Counter Mode encryption and message integrity required for high-security environments.
