An organization has configured GlobalProtect in a hybrid authentication model using both certificate- based authentication for the pre-logon stage and SAML-based multi-factor authentication (MFA) for user logon.
How does the GlobalProtect agent process the authentication flow on Windows endpoints?
- The GlobalProtect agent uses the machine certificate to establish a pre-logon tunnel; upon user sign-in, it prompts for SAML-based MFA credentials, ensuring both device and user identities are validated before granting full access.
- The GlobalProtect agent uses the machine certificate during pre-logon for initial tunnel establishment, and then seamlessly reuses the same machine certificate for user-based authentication without requiring MFA.
- Once the machine certificate is validated at pre-logon, the Windows endpoint completes MFA on behalf of the user by passing existing Windows Credential Provider details to the GlobalProtect gateway without prompting the user.
- GlobalProtect requires the user to log in first for SAML-based MFA before establishing the pre- logon tunnel, rendering the pre-logon certificate authentication (CA) flow redundant.
Answer(s): A
Explanation:
In a hybrid authentication model with both certificate-based authentication for pre-logon and SAML- based multi-factor authentication (MFA) for user logon, the GlobalProtect agent processes the flow as follows:
During the pre-logon stage, the agent uses the machine certificate to authenticate and establish the initial VPN tunnel.
Once the user logs in (after the machine is connected), the agent then triggers SAML-based MFA to ensure the user is authenticated with multi-factor authentication, validating both the device and the user identity before granting full access.
This method ensures that both the device and user are properly authenticated and validated in the hybrid authentication model.
