Read the first 6 Wireless Security Protocols (WPA) flashcards as text
How does WPA3-SAE improve upon WPA2's authentication?
Answer: SAE uses a zero-knowledge proof preventing offline dictionary attacks and providing forward secrecy
SAE uses Dragonfly key exchange proving password knowledge without transmitting it, preventing offline attacks.
What is Wi-Fi Enhanced Open (OWE)?
Answer: An encryption protocol for open networks providing individualized encryption without a password
OWE uses Diffie-Hellman key exchange to encrypt open networks without requiring passwords.
What is a KRACK attack and which protocol does it affect?
Answer: A WPA2 vulnerability forcing key reinstallation enabling traffic decryption
KRACK exploits WPA2's four-way handshake by forcing nonce reuse through replayed message 3.
What is the purpose of a WIPS (Wireless Intrusion Prevention System)?
Answer: To monitor the RF environment for unauthorized devices and attacks, and automatically respond
WIPS uses sensors to detect rogue APs, evil twins, deauth attacks, and policy violations, with automatic containment.
How does WPA3-Enterprise 192-bit mode enhance security?
Answer: It implements CNSA suite with AES-256 encryption and stronger key exchange for government-grade security
Uses CNSA-aligned algorithms: AES-256-GCMP, HMAC-SHA-384, ECDSA P-384 for highest-security environments.
What is a deauthentication attack and how does it impact wireless networks?
Answer: Sending spoofed deauth frames to disconnect clients from the legitimate AP
Attackers send forged deauth frames exploiting the unprotected nature of 802.11 management frames.
