WPA2

What is WPA2?

WPA2 (Wi-Fi Protected Access 2) is a wireless security protocol used to secure wireless networks.

It was introduced in 2004 as an upgrade to the original WPA protocol and provides stronger encryption and better security. WPA2 uses AES (Advanced Encryption Standard) encryption, which is more secure than the encryption used in WPA. It also uses a stronger key management system, called CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol). WPA2 offers two modes of operation: Personal mode, which uses a pre-shared key for authentication, and Enterprise mode, which uses a RADIUS server for authentication. Enterprise mode is more secure and scalable for larger networks. One limitation of WPA2 is that it can still be vulnerable to certain types of attacks, such as brute-force attacks and dictionary attacks. However, it is currently the most secure wireless security protocol available and is widely used to secure wireless networks. In summary, WPA2 is a wireless security protocol used to secure wireless networks. It provides stronger encryption and better security than the original WPA protocol, using AES encryption and CCMP key management. WPA2 offers two modes of operation, Personal and Enterprise, and is currently the most secure wireless security protocol available.
