Which method can be used by administrators to authenticate users on PAN devices?

Administrators can authenticate users on Palo Alto Networks devices using multiple methods, including LDAP (Lightweight Directory Access Protocol) and RADIUS (Remote Authentication Dial-In User Service). This flexibility allows organizations to leverage existing infrastructure and security policies, enhancing usability and security.

LDAP is commonly used in environments where there is a need to access and manage directory information. RADIUS, on the other hand, is frequently used for network access control, providing centralized authentication for users who are accessing secured network resources. The ability to integrate with both protocols allows the PAN devices to fit into various network security architectures and user management frameworks.

Moreover, Palo Alto Networks devices can support additional authentication methods such as TACACS+ and local database authentication, but the specific answer highlights the ability to use LDAP and RADIUS, showcasing the versatility of the device in an enterprise environment. This multi-method approach not only improves security posture but also simplifies the management of user credentials and access rights within a network.
