Difficulty: HardWireless Security Standards and Encryption Protocols

A network security administrator is tasked with deploying a wireless network across a financial organization's operations center. Executive policy mandates strict compliance with 192-bit cryptographic strength for all payload encryption, mandatory Protected Management Frames (PMF), and centralized identity validation through a RADIUS infrastructure using digital certificates. Which wireless security suite and cipher implementation must the administrator select to satisfy all organizational security mandates?

  1. A
    WPA3-Personal operating with Simultaneous Authentication of Equals (SAE) and AES-CCMP-128
  2. WPA3-Enterprise 192-bit Mode using GCMP-256 cipher suite with EAP-TLS authenticationAnswer
  3. C
    WPA2-Enterprise with AES-CCMP-128 cipher suite and EAP-PEAP authentication
  4. D
    WPA3-Personal 192-bit Mode using TKIP encryption with EAP-FAST authentication

Answer

WPA3-Enterprise 192-bit Mode using GCMP-256 cipher suite with EAP-TLS authentication
WPA3-Enterprise 192-bit mode is specifically designed for high-security government and enterprise environments requiring robust protection. It mandates 256-bit Galois/Counter Mode Protocol (GCMP-256) encryption, SHA-384 message integrity check, 802.1X authentication using EAP-TLS with strong certificates, and mandatory Protected Management Frames (PMF).

Step-by-Step Solution

1
Analyze authentication requirements
Centralized authentication using digital certificates via RADIUS requires an 802.1X EAP architecture (such as EAP-TLS), which eliminates Personal/Pre-Shared Key (PSK/SAE) modes.
Enterprise modes use 802.1X/RADIUS, whereas Personal modes use pre-shared keys or passphrase-derived keys.
2
Evaluate cryptographic strength requirements
The requirement for 192-bit cryptographic security mandates the WPA3-Enterprise 192-bit Mode operating with GCMP-256.
Standard WPA2/WPA3 Enterprise typically uses 128-bit AES-CCMP, whereas 192-bit mode strictly uses 256-bit Galois/Counter Mode Protocol (GCMP-256) along with HMAC-SHA384 and ECDSA/RSA with strong key sizes.
3
Verify Protected Management Frames (PMF) compliance
WPA3 mandates Protected Management Frames (802.1w) across all operational profiles.
PMF protection prevents management frame spoofing and disassociation attacks.
