Wi-Fi Protected Access v2 (WPA2) adds security with _____________.

1. ICMP

2. PNP

3. CCMP

4. RMPT

The correct answer is: CCMP

Wi-Fi Protected Access v2 (WPA2) enhances wireless security through the implementation of the Counter Mode with Cipher Block Chaining Message Authentication Code Protocol, commonly referred to as CCMP. This protocol is based on the Advanced Encryption Standard (AES) and provides strong data confidentiality, integrity, and authentication for wireless communications. CCMP is essential because it addresses vulnerabilities found in the older WEP (Wired Equivalent Privacy) encryption method by utilizing more secure cryptographic methods. Unlike its predecessor, TKIP (Temporal Key Integrity Protocol), which was still susceptible to certain types of attacks, CCMP operates with a more robust encryption algorithm and a significantly stronger key management mechanism, thus ensuring that data transmitted over a Wi-Fi network is much less likely to be intercepted or tampered with. In the context of WPA2, CCMP enables the establishment of secure connections between devices and access points, ensuring that sensitive information remains protected from unauthorized access. This makes CCMP a critical component of the WPA2 security framework, solidifying its role in modern wireless security strategies.
