Authentication Policy

Authentication policy enables you to authenticate end users before they can access services and applications. Whenever a user requests a service or application (such as by visiting a web page), the firewall evaluates Authentication policy. Based on the matching Authentication policy rule, the firewall then prompts the user to authenticate using one or more methods (factors), such as login and password, Voice, SMS, Push, or One-time Password (OTP)authentication. For the first factor, users authenticate through a Captive Portal web form. For any additional factors, users authenticate through a Multi-Factor Authentication (MFA) login page.
To implement Authentication policy for GlobalProtect, refer to Configure GlobalProtect to Facilitate Multi-Factor Authentication Notifications.
After the user authenticates for all factors, the firewall evaluates Security Policy to determine whether to allow access to the service or application.
To reduce the frequency of authentication challenges that interrupt the user workflow, you can specify a timeout period during which a user authenticates only for initial access to services and applications, not for subsequent access. Authentication policy integrates with Captive Portal to record the timestamps used to evaluate the timeout and to enable user-based policies and reports.
Based on user information that the firewall collects during authentication, User-ID creates a new IP address-to-username mapping or updates the existing mapping for that user (if the mapping information has changed). The firewall generates User-ID logs to record the additions and updates. The firewall also generates an Authentication log for each request that matches an Authentication rule. If you favor centralized monitoring, you can configure reports based on User-ID or Authentication logs and forward the logs to Panorama or external services as you would for any other log types.
