Which four authentication servers can you use with your Firebox?

While Active Directory is indeed a valid option for authentication with a Firebox, multiple other authentication servers are also compatible. The correct answer includes a combination of options.

Using Active Directory allows the Firebox to authenticate users securely, integrating with the existing Windows domain infrastructure. It is widely utilized in organizational environments.

RADIUS (Remote Authentication Dial-In User Service) is also supported by Firebox for managing network access. It provides centralized authentication for users accessing the network, which is essential for scenarios involving VPN access or other remote services.

LDAP (Lightweight Directory Access Protocol) is another supported authentication method. It is commonly used for querying and modifying directory services running over TCP/IP, such as user information systems.

Kerberos is a network authentication protocol designed to provide strong authentication for client/server applications. It works based on tickets and is also compatible with Firebox for federated authentication scenarios.

Firebox databases serve as a local form of user verification but do not fall under the category of external authentication servers that are typically used for broader network management or directory access, which is why they might not be included in a selection that aims to reflect authentication servers used with Firebox in professional settings.

Overall, these authentication methods enable organizations to ensure secure and efficient access to
