Which type of encryption improves upon WEP and provides better security for wireless networks?

WPA2 is the type of encryption that significantly enhances security for wireless networks compared to WEP (Wired Equivalent Privacy). WPA2 utilizes the Advanced Encryption Standard (AES), which is a more robust and secure encryption method than the RC4 stream cipher used in WEP. This makes WPA2 better at safeguarding the data transmitted over wireless connections, providing stronger protection against various types of attacks, such as eavesdropping and unauthorized access.

Additionally, WPA2 includes features such as improved authentication methods and support for more complex passphrases, further bolstering the security of the network. By using WPA2, network administrators can ensure that wireless communications are encrypted in a way that provides confidentiality and integrity of the data shared over the network, making it the standard for secure wireless communication.
