Which encryption method is frequently used for securing wireless networks?

WPA2, or Wi-Fi Protected Access 2, is widely recognized as the security standard for protecting wireless networks. It utilizes robust encryption methods to provide a high level of security for data transmitted over Wi-Fi connections. Unlike its predecessor, WEP (Wired Equivalent Privacy), which is now considered outdated and vulnerable to many security flaws, WPA2 employs the Advanced Encryption Standard (AES) for encryption. This makes WPA2 significantly more secure, as AES is a strong encryption algorithm widely used across various applications.

WPA2 not only supports AES but also improves upon security protocols by using a more complex handshake process for authentication that helps protect against unauthorized access to the network. This makes WPA2 the preferred choice for securing modern wireless networks, providing confidentiality, integrity, and authenticity for the data being transmitted.
