Which of the following provides security for wireless networks?

1. WEP

2. WPA

3. WPA2

4. 802.1X

The correct answer is: WPA2

WPA2 is a security protocol specifically designed to provide robust protection for wireless networks. It employs the Advanced Encryption Standard (AES) for data encryption, making it significantly more secure compared to its predecessors, such as WEP and WPA. WPA2 also includes a more secure authentication process through the use of a pre-shared key (PSK) or the IEEE 802.1X standard for enterprise environments, which helps to ensure that only authorized users have access to the network. In addition to its strong encryption, WPA2 addresses vulnerabilities found in earlier protocols, enhancing overall network security and protecting sensitive data transmitted over wireless connections. This makes it the preferred choice for securing wireless networks, especially in environments where data integrity and confidentiality are paramount.
