Which of the following represents a built-in method of obtaining user identity for policy enforcement?

• A. Remote Access
• B. RADIUS
• C. Active Directory Query
• D. Portable Device Sign-in

Answer: (B)

RADIUS (Remote Authentication Dial-In User Service) is a widely used protocol that provides centralized Authentication, Authorization, and Accounting (AAA) for users who connect and use a network service. RADIUS servers authenticate users attempting to access a network based on various criteria, granting or denying access according to pre-defined policies. This integration is crucial for enforcing security policies effectively across multiple systems. Using RADIUS for obtaining user identity allows for the enforcement of policies based on user attributes, including group memberships or roles within an organization. This functionality is essential in a security infrastructure where understanding the identity of users and applying appropriate policies based on that identity is critical for maintaining security standards. Other methods, such as Remote Access, Active Directory Query, and Portable Device Sign-in, also play roles in user management and authentication but do not represent built-in methods specifically focused on policy enforcement in a centralized manner. Remote Access generally pertains to connecting securely to a network, while Active Directory queries involve retrieving or validating user data from a directory service, which may not directly link to policy enforcement. Portable Device Sign-in usually addresses access methods rather than the underlying user authentication process for policy application.
