What is a significant improvement of WPA2 over WEP?

WPA2 represents a significant improvement over WEP primarily through its use of a stronger encryption method. WPA2 employs the Advanced Encryption Standard (AES), which is significantly more secure than the RC4 encryption used by WEP. This increased security ensures better protection against various types of attacks, such as eavesdropping and unauthorized access, which were prevalent with WEP due to its vulnerabilities.

The key to WPA2's effectiveness lies in its improved key management and encryption protocols, which not only enhance the security of the transmitted data but also offer better support for modern security practices compared to the outdated and weak WEP standard. These advancements help in safeguarding sensitive information transmitted over wireless networks, making WPA2 a fundamental choice for securing Wi-Fi environments.
