Difficulty: Very hardWireless Security and Authentication

A network technician is configuring an enterprise wireless network for a corporate environment. The organization's security policy mandates individual user-based authentication integrated with a RADIUS server, strict mutual authentication enforcing client-side digital certificates on corporate-managed laptops, and strong modern encryption protocols without relying on password-only authentication. Which of the following wireless security standards and EAP protocols best meets these requirements?

  1. WPA3-Enterprise utilizing EAP-TLSAnswer
  2. B
    WPA3-Enterprise utilizing PEAP-MSCHAPv2
  3. C
    WPA3-Personal utilizing Simultaneous Authentication of Equals (SAE)
  4. D
    WPA2-Personal utilizing TKIP encryption and 802.1X RADIUS

Answer

WPA3-Enterprise utilizing EAP-TLS is the correct choice because EAP-TLS enforces mutual authentication requiring digital certificates on both the authentication server and the client device.
WPA3-Enterprise uses 802.1X port-based network access control to interface with a RADIUS server. EAP-TLS (Extensible Authentication Protocol - Transport Layer Security) requires mutual authentication, meaning both the authentication server and the client device must present valid, trusted digital certificates. This satisfies the security policy for client certificate enforcement.

Step-by-Step Solution

1
Analyze the organizational security requirements outlined in the prompt.
The requirements demand 802.1X RADIUS integration (enterprise mode) and mandatory client-side digital certificate authentication.
Personal modes (PSK/SAE) rely on shared passphrases, whereas Enterprise modes integrate with RADIUS servers for individual credentials.
2
Evaluate the authentication capabilities of candidate EAP protocols.
EAP-TLS (Transport Layer Security) mandates certificate-based mutual authentication for both client and server. PEAP-MSCHAPv2 uses server certificates but client passwords.
Only EAP-TLS satisfies the strict requirement for client-side digital certificate verification.
3
Select the modern wireless security framework.
WPA3-Enterprise with EAP-TLS provides 192-bit enterprise security mode support alongside robust encryption standards.
WPA3-Enterprise combined with EAP-TLS represents the highest assessment standard for secure corporate wireless deployment.
