Which types of authentication methods can be used with GlobalProtect?

The correct answer highlights the versatility and security options available with GlobalProtect, which is a VPN solution from Palo Alto Networks. GlobalProtect supports various authentication methods, ensuring that organizations can implement robust security measures tailored to their specific needs.

Certificate-based authentication is crucial because it uses digital certificates to verify the identity of users or devices, enhancing security by requiring valid certificates issued by trusted certificate authorities. Multi-factor authentication (MFA) adds an additional layer of security by requiring users to provide two or more verification factors to gain access, thereby significantly reducing the risk of unauthorized access. RADIUS (Remote Authentication Dial-In User Service) is widely used for authentication, authorization, and accounting. It is a protocol that provides centralized authentication for users connecting remotely, making it particularly suitable for environments with various user access points.

This combination of authentication methods enables organizations to enforce strong access controls and ensure that only legitimate users can connect to the network, thus improving overall security posture. Other options either limit the types of authentication methods available or focus on less secure or single-layer authentication processes, which do not provide the same level of protection as what GlobalProtect offers in option C.
