A company wants to reduce the number of login IDs and passwords their employees need to remember to access various company resources. Which authentication scheme should a security administrator recommend to achieve this?
Single sign-on (SSO) is an authentication scheme that allows a user to use a single set of credentials (like a username and password) to access multiple different applications and resources. This directly addresses the company's goal of reducing the number of logins employees must manage.
RADIUS and TACACS+ are AAA (Authentication, Authorization, and Accounting) protocols, primarily used for centralizing authentication for network access (like Wi-Fi or VPNs) or network device administration, respectively. They do not provide the seamless single-login experience across various applications that SSO offers.
802.1X is a port-based network access control (PNAC) standard used to authenticate devices before they are allowed to connect to a network. It is not used for authenticating users to applications.
