One major benefit of using RADIUS (Remote Authentication Dial-In User Service) is that it provides centralized access control for users. This means that all user authentication requests are sent to a central server, allowing for unified management of access control policies. Organizations can implement consistent authentication mechanisms across multiple network devices, which streamlines the process of managing user access credentials.

Centralized access control is particularly advantageous in larger environments where numerous devices and services need to authenticate users. With RADIUS, changes to user access rights or authentication methods can be made at a central point, greatly simplifying administration and ensuring that security policies are uniformly applied. This centralized approach also aids in auditing and compliance, as logs and records can be easily aggregated from one location, providing a complete view of user access and activity.

Utilizing RADIUS does not eliminate the need for encryption; in fact, it often uses encryption mechanisms to secure the authentication process. Additionally, while it may enhance overall organizational security by ensuring that only legitimate users gain access, RADIUS itself is not designed to enhance physical security of systems, which is typically addressed through different measures.
