Which wireless security protocol is considered the most secure for modern enterprise networks?
Answer: WPA3-Enterprise
WPA3-Enterprise provides the strongest wireless security using 192-bit cryptographic strength and SAE for authentication, replacing vulnerable WPA2 mechanisms.
What type of wireless attack involves setting up an unauthorized access point that mimics a legitimate one to intercept user traffic?
Answer: Evil twin attack
An evil twin attack creates a rogue access point with the same SSID as a legitimate network, tricking users into connecting so the attacker can intercept traffic.
WPA3 uses which key exchange mechanism to provide forward secrecy and resistance to offline dictionary attacks?
Answer: Simultaneous Authentication of Equals (SAE)
WPA3 uses SAE (also known as the Dragonfly handshake) for key exchange, providing forward secrecy so captured traffic cannot be decrypted later.
What is the primary function of a Wireless Intrusion Prevention System (WIPS)?
Answer: Detect and block unauthorized wireless devices and attacks
A WIPS monitors the radio frequency spectrum to detect rogue access points, unauthorized clients, and active attacks, then automatically responds to block them.
Which authentication framework requires a RADIUS server and provides centralized user authentication in enterprise wireless deployments?
Answer: 802.1X
802.1X is an IEEE standard for port-based network access control that uses EAP and a backend RADIUS server for centralized, per-user authentication.
What security limitation makes SSID cloaking (hiding the network name) an ineffective standalone security control?
Answer: Hidden SSIDs are still visible in probe requests captured by passive scanners
Even when beacon broadcasts are suppressed, the SSID is still transmitted in probe requests and responses, making it trivially discoverable with wireless scanning tools like Wireshark.
Which IEEE 802.11 wireless standard introduced the 6 GHz frequency band to reduce congestion and improve performance?
Answer: 802.11ax (Wi-Fi 6E)
802.11ax Wi-Fi 6E extends into the 6 GHz band, providing additional spectrum, less interference, and higher throughput compared to prior standards limited to 2.4/5 GHz.
