2.3 Wireless Security Flashcards
What is the primary weakness of WEP (Wired Equivalent Privacy)?
Uses weak encryption with a static key and is easily cracked.
What type of encryption does WPA (Wi-Fi Protected Access) use?
TKIP (Temporal Key Integrity Protocol) with RC4 encryption.
What improvement does WPA2 have over WPA?
Uses AES encryption with CCMP, making it more secure.
What is the latest Wi-Fi security standard?
WPA3.
How does WPA3 improve security over WPA2?
Uses Simultaneous Authentication of Equals (SAE) instead of PSK, providing better resistance to brute force attacks.
What is the main advantage of using WPA2 Enterprise over WPA2 Personal?
Enterprise mode uses 802.1X authentication for enhanced security.
Why is MAC filtering not a strong security measure?
MAC addresses can be easily spoofed.
What does disabling SSID broadcast do?
Hides the network name but does not prevent detection with sniffing tools.
What is the recommended Wi-Fi security protocol for most networks today?
WPA2 with AES encryption.
What is the purpose of TKIP in WPA?
To improve encryption security over WEP, but it is now outdated.
Why should WEP never be used?
It has severe security flaws and can be hacked in minutes.
What is the main weakness of WPA?
It still uses RC4 encryption, which is vulnerable to attacks.
What does AES stand for in WPA2 security?
Advanced Encryption Standard.
Why should WPS (Wi-Fi Protected Setup) be disabled?
It is vulnerable to brute-force attacks.
What is one of the strongest security measures for Wi-Fi networks?
Using WPA2/WPA3 with a long, complex password.
