WPA2

WPA2, also known as Wi-Fi Protected Access 2, is a security protocol used to protect the integrity of wireless networks. Developed by the Wi-Fi Alliance and released in 2004, WPA2 is the current standard for secure wireless networks and provides a number of cryptographic technologies, including strong encryption and authentication capabilities. WPA2 has become the standard for wireless network security due to its strong encryption and authentication capabilities.

WPA2 is an improvement over its predecessor, WPA (Wi-Fi Protected Access). WPA was designed to fix the insecurity in the original Wi-Fi security protocol, WEP (Wired Equivalent Privacy), which had numerous loopholes and vulnerabilities. WPA2 improved on WPA by implementing the Advanced Encryption Standard (AES) instead of the TKIP encryption protocol, among other enhancements.

WPA2 networks require that all users have a passphrase, or authentication key, in order to gain access. This is known as 802.1X authentication, which is an essential component of WPA2 networks. WPA2 also uses a complex algorithms designed to ensure that only legitimate users can gain access to the network by using the authentication key.

WPA2 networks have become the standard for secure wireless networks and are recommended for those seeking to protect their confidential data. The Wi-Fi Alliance recommends that users upgrade to WPA2 networks and devices supporting WPA2 as soon as possible.
