Explanation
RADIUS (Remote Authentication Dial-In User Service) is a centralized AAA (Authentication, Authorization, and Accounting) protocol. When integrated with 802.1X on a wireless network, RADIUS authenticates users against a central directory (such as Active Directory), allowing the same credentials used to log into the domain to also authenticate the user to the WiFi network - providing Single Sign-On (SSO). WPA2 is a wireless security standard (encryption/authentication framework), not an SSO mechanism itself. AES is an encryption algorithm used within WPA2. MAC filtering restricts access by device hardware address, not by user identity. WPS simplifies device pairing but has known vulnerabilities and offers no SSO capability.
