Identify and Quarantine Compromised Devices
Prisma Access allows you to identify and quarantine compromised devices with the GlobalProtect app. You can either manually or automatically (based on auto-tags) add devices to a quarantine list. You can block quarantined devices from accessing the network or restrict the device traffic based on a security rule.
To get started, set up a Quarantined Device List. Then use the list as part of identity redistribution.
Set Up a Quarantined Device List
The Quarantined Device List screen is where you identify devices you want to block from accessing your network.
Follow these steps to add a device to the Quarantined Device List:
- Selectfrom the sidebar.ManageConfigurationObjectsQuarantined Device ListTheSharedconfiguration scope is already selected for you. Leave this option as is.
- SelectAdd Device.
- Fill in theHost IDandSerial Numberfields.
- Repeat steps 1-4 to add additional devices.
Configure Identity Redistribution
The Identity Redistribution screen is where you configure how identity information is redistributed in the Prisma Access Infrastructure. Configure identity redistribution to use the quarantined device list so that all devices on the network that enforce policy know to block the compromised devices.
Follow these steps to configure identity redistribution to use the Quarantined Device List you created:
- Selectfrom the sidebar.ManageConfigurationIdentity ServicesIdentity Redistribution List
- Select the appropriate configuration scope, Shared or Mobile Users.You can ignore Service Connections for now because Service connections learn from mobile users, remote networks, or external redistribution agents, as shown in the diagram. If you’re unsure about which to select, see Global and Local Policy.Sharedis selected by default.
- SelectEditnext toMobile Users.
- Select the checkbox next to theQuarantined Device List.
- SelectSave.Learn more about Identity Redistribution. See Identification and Quarantine of Compromised Devices With Prisma Access to learn about specific use cases. This topic is for Panorama administrators, but the concept applies to Prisma Access in general.
Block Login for Quarantined Devices
Block quarantined devices from accessing the network, or block users from logging into the network from devices on the Quarantined Device List.
Follow these steps to configure Authentication Settings to prevent users from logging into GlobalProtect from a quarantined device:
- Selectfrom the sidebar.SettingsPrisma Access SetupGlobalProtect
- Scroll down toUser Authenticationsand selectAuthentication Settings.TheAuthentication Settingsscreen appears.
- Select the checkbox forBlock Login for Quarantined Devices.
Use Quarantine Device List for Security Policy Enforcement
Prevent quarantined devices from sending or receiving traffic on the network by specifying options in a security policy rule.
Follow these steps to configure Security Policy to use your Quarantined Device List to prevent quarantined devices from sending or receiving traffic on the network:
- Selectfrom the sidebar.ManageConfigurationSecurity ServicesSecurity Policy
- Scroll down toSecurity Policy Rulesand selectAdd Rule.TheAdd Security Policy Rulescreen appears.
- Scroll down toDEVICESunder eitherSourceorDestinationand selectMatch Quarantined Devices.This tells your rule to use devices in the quarantine list as the match criteria, whether you specify Quarantine as the Source Device for Source traffic or the Destination Device for Destination traffic.
- UnderAction and Advanced Inspection, specify an action that blocks the quarantined device, such asDenyas required by your rule.
