Wireless local area networks (WLANs) rely on security protocols to protect data transmitted over radio waves. Regarding the Wi-Fi Protected Access 3 (WPA3) security standard, which of the following statements are correct?

  1. It replaces the traditional Pre-Shared Key (PSK) handshake with Simultaneous Authentication of Equals (SAE) to prevent offline dictionary attacks.Cevap
  2. It mandates the implementation of Protected Management Frames (PMF) to shield management traffic from eavesdropping and spoofing.Cevap
  3. It enforces Forward Secrecy to ensure that compromised long-term network credentials cannot be used to decrypt previously recorded traffic.Cevap
  4. D
    It completely eliminates the use of symmetric encryption algorithms and cryptographic hash functions to reduce packet processing overhead.

Cevap

The correct statements are those identifying the replacement of PSK with SAE, the mandatory use of Protected Management Frames (PMF), and the enforcement of Forward Secrecy.
WPA3 introduces critical architectural enhancements over WPA2, including Simultaneous Authentication of Equals (SAE) to stop offline dictionary attacks, mandatory Protected Management Frames (PMF) to prevent forged disconnect commands, and Forward Secrecy to protect past network traffic from retroactive decryption.

Adım Adım Çözüm

1
Analyze key authentication mechanism updates in WPA3.
WPA3 adopts Simultaneous Authentication of Equals (SAE) instead of the 4-way PSK handshake used in WPA2 Personal.
SAE utilizes the Dragonfly key exchange algorithm, preventing attackers from capturing the handshake and guessing passwords offline.
2
Evaluate frame protection requirements.
Protected Management Frames (PMF) are mandatory across all WPA3 connections.
PMF prevents unauthorized actors from forging administrative packets, such as disassociation or deauthentication frames, to disconnect users.
3
Examine session security and cryptographic foundations.
WPA3 provides Forward Secrecy and continues to use authenticated symmetric encryption (AES) and cryptographic hashing.
Forward Secrecy protects historic data sessions if password credentials are leaked in the future, while ciphers and hashes provide confidentiality and integrity.
