What is WPA2 primarily used for in wireless networks?

WPA2, or Wi-Fi Protected Access II, is primarily used for data encryption in wireless networks. It enhances security by providing robust encryption methods to protect data transmitted over the network. This ensures that the information exchanged between devices is not easily intercepted or understood by unauthorized users. WPA2 uses the Advanced Encryption Standard (AES), which is a strong encryption protocol that helps safeguard sensitive information from potential attacks.

The emphasis on encryption is vital in wireless environments, as wireless signals are inherently more susceptible to eavesdropping compared to wired connections. By using WPA2, networks can maintain the confidentiality and integrity of the data shared, which is essential in safeguarding personal and sensitive information, especially in public or shared networks. This focus on encryption distinguishes WPA2 from other functions such as data compression, data transmission, or data formatting, which are not its primary purpose.
