Identification and Quarantine of Compromised Devices in a Prisma Access GlobalProtect Deployment

Configure Quarantine List Redistribution in Prisma Access

Use Cases for Quarantine List Redistribution

Learn about the times you can use a quarantine list in a Prisma Access GlobalProtect deployment.

The following section describes some common Prisma Access deployments where quarantine list redistribution is useful for consistent policy enforcement for compromised devices.

Quarantine List Redistribution between Mobile User Locations Connected to Same Service Connection—In the following example, a GlobalProtect Mobile User who is connected to Mobile User Location 1 becomes compromised and is auto-quarantined. Prisma Access blocks or restricts the quarantined device per policy.

A service connection (Service Connection 1 in this example) redistributes the quarantine list information between all mobile user locations to which it is connected. Since Mobile User Location 2 receives the redistributed quarantine list information by way of Service Connection 1, the GlobalProtect mobile user attempt to connect to Mobile User Location 2 is also blocked.
Quarantine List Redistribution between Mobile User Locations Connected to Different Service Connections—In the following example, there are two mobile user locations, but they connect to two different service connections. A GlobalProtect user attempted to connect to Mobile User Location 1. Mobile User Location 1 detects the GlobalProtect user endpoint as compromised and quarantines it.

To redistribute the quarantine list information from Mobile User Location 1 to Mobile User Location 2, perform the following actions:
- Redistribute the quarantine list information from Service Connection 1 to Panorama.
- Redistribute the quarantine list information from Panorama to Service Connection 2.
With this configuration, when the GlobalProtect user connects to Mobile User Location 1 and is quarantined, then the quarantine list information redistributes from Mobile User Location 1 to Mobile User Location 2 and any connection attempts to Mobile User Location 2 are blocked.

This configuration is also valid if the GlobalProtect user connects to Mobile User Location 2 and is quarantined; the quarantine list information redistributes from Mobile User Location 2 to Mobile User Location 1.
Quarantine List Redistribution Between Prisma Access and a Next-Generation Firewall or Gateway—In the following example, A GlobalProtect user attempted to connect to Mobile User Location 1. Mobile User Location 1 detects the GlobalProtect user endpoint as compromised and quarantines it. The mobile user then goes to the company’s headquarters and attempts to log in again. The headquarters is protected with a next-generation firewall configured as a GlobalProtect gateway using Internal Host Detection.
Mobile User Location 1 redistributes the quarantine list information to Panorama through Service Connection 1, and Panorama redistributes the quarantine list information to the on-premise internal gateway. When the user attempts to log in from the headquarters location, GlobalProtect detects that the on-premises gateway is configured as an internal gateway and connects to the gateway without a tunnel.
Since the quarantine list information has been redistributed to the on-premises gateway, the user is blocked at the gateway based on the configured user policies.

If you use a next-generation firewall or gateway with Prisma Access, you should configure Panorama to redistribute quarantine list information to the firewall or gateway, all service connections, and Panorama.
Administrator Manually Quarantines Mobile User at Panorama—In this example, the Prisma Access administrator has manually added a mobile user to the quarantine list at the Panorama appliance that manages Prisma Access. The administrator has set up redistribution between Panorama, the next-generation firewall, and the service connections. Panorama redistributes the updated quarantine list information to the firewall and the service connections. The service connections then redistribute the quarantine list information to the mobile user locations.
The mobile user was connected to Mobile User Location 1. After Mobile User Location 1 receives the updated quarantine list information, the user is disconnected. If the user attempts to connect to Mobile User Location 2, the connection is blocked and the mobile user receives a quarantine notification.
Mobile User is Auto or Manually Quarantined at the On-Premises Gateway—In this example, there is a next-generation firewall that has been configured as an external gateway at the headquarters or data center location. The administrator has manually quarantined a mobile user at the external gateway. The external gateway redistributes the quarantine list information from the external gateway to Panorama.
After Panorama has received the updated quarantine list information from the external gateway, it redistributes that information to Service Connections 1 and 2, which then redistributes it to Mobile User Locations 1 and 2. If a mobile user attempts to connect to either Mobile User Location 1 or 2, Prisma Access blocks the connection and the user receives a a quarantine notification.
