Which technology can provide secure SSO access for WiFi and network resources in a wireless environment?

RADIUS (Remote Authentication Dial-In User Service) is a protocol specifically designed for user authentication, authorization, and accounting in network environments, making it well-suited for providing secure Single Sign-On (SSO) for WiFi and network resources. RADIUS supports various authentication methods, including EAP (Extensible Authentication Protocol), which can facilitate secure connections in wireless environments. By using RADIUS, organizations can centralize user management and enforce security policies while allowing users to access multiple network services with a single set of credentials.

WPA2 (Wi-Fi Protected Access 2) provides a strong encryption mechanism for wireless networks, enhancing wireless security but not directly focusing on SSO capabilities. AES (Advanced Encryption Standard) is an encryption standard utilized for securing data, including in WPA2, but it does not handle user authentication or SSO.

MAC filtering allows only specific devices with approved MAC addresses to connect to the network, but it is not a secure method for user authentication and does not facilitate SSO. Therefore, RADIUS stands out as the technology that can effectively provide secure SSO access for WiFi and network resources.
