Configure User-ID based Policy Rules

Where Can I Use This?	What Do I Need?
Prisma SD-WAN (Managed by Strata Cloud Manager)	Prisma SD-WAN

Prisma SD-WAN supports User-ID based policies, wherein you can configure policies directly for a user or a group of users. You can use the user name or the group name as part of a policy rule for path, QoS, and security policies.

You can apply User-ID based policies only to tenant service group (TSG) compatible tenants.

Workflow

The PAN-OS firewall (either an on-prem NGFW or Prisma Access cloud firewall) maps IP addresses to users. The Cloud Identity Engine maps users to user groups.

1. A data center ION device learns the User-ID mapping from a User-ID Agent running on a PAN-OS firewall. The User-ID client software runs on the data center ION device.
   ION devices support only those PAN-OS firewalls running versions 10.1.7, 10.2.3, 11.0.x, or higher.
2. The DC ION device pushes the User-ID to IP address mapping to the Prisma SD-WAN controller.
3. The Prisma SD-WAN controller interacts with the Cloud Identity Engine for User ID to User Group mapping.
4. The Prisma SD-WAN controller distributes these mappings to branches (after site-specific filtering based on prefixes and policies).
5. The Prisma SD-WAN controller pushes User-ID based policies to branch site ION devices.
6. The branch ION devices apply User-ID based policies.
7. The branch ION devices tag the Prisma SD-WAN traffic with user name information for site-to-site traffic over the Prisma SD-WAN VPNs
8. The branch ION devices use the tag (username) received in the WAN traffic to enforce User-ID based policies for remote site users.
9. The branch ION devices send stats/logs for User ID/Group ID used in the policies to the controller.

Prisma SD-WAN supports WAN to LAN User-ID based policies for traffic between branch sites with direct tunnels, but it does not support User-ID based policies for traffic that originates from or transits through a data center.

You will need the following licenses and subscriptions in the same tenant service group (TSG) that Prisma SD-WAN belongs to, in order to configure User-ID based policies in Prisma SD-WAN.

• PAN-OS firewall
• Cloud Identity Agent activation

Use the following steps to configure User-ID based policies in Prisma SD-WAN.

1. Set up the connection to the User-ID agent.

   Configure a data center ION device to connect to the User ID Agent in the PAN-OS firewall.

   1. Select ConfigurationPrisma SD-WANData Centers and then select a data center site.
   2. In the Configuration tab, click Configure User Agent.
   3. Click Add User Agent.

      1. Enter a Name for the User Agent configuration.
         You can choose to disable the connection between the user agent client and the user agent running on the PAN-OS firewall by selecting the Disabled check box.
      2. Enter the Host IP address or a fully qualified domain name (FQDN)for the PAN-OS firewall.
         If you specify an FQDN, use the down-level logon name in the (DLN)\sAMAccountName format instead of the FQDN\sAMAccountName format. For example, use example\user.services not example.com\user.services.
      3. Enter the Port number for the PAN-OS firewall.
      4. (Optional) Enter a Collector Name.
         Enter this information if you are using a Virtual System (hardware firewall).
      5. (Optional) Enter a Collector Pre-Shared Key and confirm.
      6. Submit your configuration.
2. Configure user attributes.

   1. Select ConfigurationPrisma SD-WANSystemCloud Identity Engine.
   2. Click Configure Identity Engine.

      The formats supported are:

      • User Principal Name—User-id@domain.com
      • SAM Account Name—NetBIOS/User-ID format
        When the username format is a SAM Account Name, Prisma SD-WAN supports only the netbios\<user> format and not the domain\<user> format.
3. Add users and/or user groups in policy rules.

   You can add users or user groups in path, QoS, and security policy rules.

   1. Select ConfigurationPrisma SD-WANPoliciesPathsPath StacksSimple, select a stack and click Add Rule.
   2. On the Users tab, select a User and/or a Group from the User/Group drop-down.

      The default value is Any. An explicitly specified user name has priority over a group name. An explicitly specified group name has priority over any/known/unknown user.
