Wireless Encryption Algorithms

What is the primary vulnerability associated with WEP (Wired Equivalent Privacy)?

• Brute-force attacks

• Dictionary attacks

• Weak key management

• Man-in-the-middle attacks

Which encryption algorithm is considered more secure than WEP and is widely used in WPA2 and WPA3?

• AES

• TKIP

• RC4

• DES

WPA2 primarily uses Pre-Shared Key (PSK) mode, where a passphrase is shared among users. While this mode is convenient, it can be susceptible to brute-force and dictionary attacks.

• True

• False

WPA3 enhances key management by introducing Simultaneous Authentication of Equals (SAE), a secure key exchange protocol that protects against offline dictionary attacks

• True

• False

Which WPA3 feature protects against offline dictionary attacks during key exchange?

• AES-CCMP

• Simultaneous Authentication of Equals (SAE)

• Temporal Key Integrity Protocol (TKIP)

• AES

Which Wi-Fi security protocol is more resistant to brute-force attacks due to its key management improvements?

• WPA2

• WEP

• WPA3

• WPA

What does CCMP stand for in the context of Wi-Fi encryption?

• Counter Mode Cipher Block Chaining Message Authentication Code Protocol

• Cryptographic Control Message Protocol

• Cipher Chain Message Protection

• Controlled Cryptography and Message Privacy

Which encryption mode is used in WPA3 for data confidentiality in Wi-Fi networks?

• Counter Mode (CTR)

• Cipher Block Chaining (CBC)

• Galois/Counter Mode (GCM)

In WPA2, all devices on the network use the same encryption key, which means if one device's key is compromised, all devices are affected.

• True

• False

WPA3 introduces individualized data encryption, ensuring that even if one device's key is compromised, the security of other devices on the network remains intact.

• True

• False
