The technology often used for securing wireless networks is WPA2 (Wi-Fi Protected Access 2). WPA2 is a security protocol designed to provide a strong level of encryption and authentication for wireless networks, protecting data transmitted between devices and access points. By utilizing AES (Advanced Encryption Standard), WPA2 ensures that even if data is intercepted, it remains unreadable without proper credentials. This level of security is essential for both personal and business networks, helping to safeguard sensitive information against unauthorized access and cyber threats.
