CCMP stands for Counter Mode CBC MAC Protocol. This protocol is a part of the IEEE 802.11i standard, which is critical for providing encryption and integrity protection for data in wireless networks. CCMP uses the Advanced Encryption Standard (AES) in counter mode for encryption, offering a robust level of security that is essential in protecting sensitive information transmitted over wireless mediums.

The use of Counter Mode combined with Cipher Block Chaining Message Authentication Code (CBC-MAC) allows for both confidentiality and integrity of the data. In contrast to other protocols, CCMP is designed to address vulnerabilities present in older protocols, such as WEP, by providing strong security features to ensure the integrity and privacy of the transmitted data.

In this context, CCMP's designation as the standard for encryption in Wi-Fi networks emphasizes its importance in network security, particularly in preventing unauthorized access and ensuring secure communications in a potentially hostile environment such as wireless communication. This is why CCMP is the correct answer, highlighting its significance in maintaining the security of network communications.
