    Prisma Access

    So that you can enforce your security policy consistently, Prisma Access shares identity data that GlobalProtect discovers locally across your entire Prisma Access environment.
    So that you can enforce your security policy consistently, Prisma Access shares identity data that GlobalProtect discovers locally across your entire Prisma Access environment. Prisma Access can also share identity data with on-premises devices at remote network sites or service connection sites (HQ and data centers).
    For Prisma Access Cloud Management, we’ve enabled some identity data redistribution by default, and for what’s left, we’ve made the configuration to enable redistribution very simple (just select a checkbox to select what data you want to share).
    From the Identity Distribution dashboard, you can see how identity data is being shared and manage data redistribution (
    Manage
    Configuration
    Identity Services
    Identity Redistribution
    .
    Identity data that you can redistribute includes:
    • HIP data
    • IP-address-to-tag mappings
    • IP-address-to-user mappings
    • User-to-tag mappings
    • Quarantined devices
    Get started with identity redistribution:

    How Identity Redistribution Works

    For mobile users to access a resource at a remote network location or HQ/data center that’s secured by a device with user-based policies, you must redistribute the identity data from the Prisma Access mobile users and users at remote networks to that on-premises device.
    When the users connect to Prisma Access, Prisma Access collects the user’s identity data and stores it.
    The following example shows two mobile users that have an existing IP address-to-username mapping in Prisma Access. Prisma Access then redistributes this mapping by way of a service connection to the on-premises devices that’s securing the HQ/data center.
    Prisma Access Cloud Management automatically enables service connections to work as identity redistribution agents (also called User-ID agents).

    Set Up Identity Redistribution

    • Confirm Your Service Connection Setup
      If you haven’t yet set up a service connection for your HQ or data centers, begin by configuring a service connection. A service connection is required for Prisma Access to share identity data across your environment; Prisma Access automatically enables service connections to work as redistribution agents. A newly-created service connection site will be ready to be used as a redistribution agent when you see that it's been assigned a User-ID Agent Address (Prisma Access does this automatically, and it'll just take a few minutes). Go to
      Manage
      Configuration
      Identity Services
      Identity Redistribution
       and set the configuration scope to
      Service Connections
       to verify the service connection User-ID agent details.
    • Send Identity Data from Prisma Access to On-Premises Devices
      The service connection’s User-ID agent information is all you need to configure Prisma Access to distribute identity data to on-premises devices.
      Go to
      Manage
      Configuration
      Identity Services
      Identity Redistribution
       and set the configuration scope to
      Service Connections
       to get the service connection User-ID agent details.
      Use these details to configure Prisma Access as a data redistribution agent on Panorama or a next-gen firewall.
    • Send Identity Data from On-Premises Devices to Prisma Access
      Add on-premises devices to Prisma Access as redistribution agents; the devices you add will be able to distribute identity data to Prisma Access.
      • From devices at remote network sites:
        Go to the
        Identity Redistribution
         dashboard, set the configuration scope to
        Remote Networks
        , and
        Add Agent
        . In addition to specifying the host details, select the type of data the device shares with Prisma Access. Optional settings include the name and a pre-shared key for the device.
      • From devices at service connection sites:
        Go to the
        Identity Redistribution
         dashboard, set the configuration scope to
        Service Connections
        , and
        Add Agent
        . In addition to specifying the host details, select the type of data the device shares with Prisma Access. Optional settings include the name and a pre-shared key for the device.
    • Configure the Terminal Server Agent for User Mapping
      The Terminal Server (TS) Agent allocates a port range to each user to identify specific users on Windows-based terminal servers. The TS Agent notifies Prisma Access of the allocated port ranges, so that Prisma Access can enforce policy based on users and user groups.
      On the
      Identity Redistribution
       dashboard, set the configuration scope to
      Remote Networks
      , and
      Add Terminal Server Agent
       under
      Terminal Server Sending to Remote Networks Nodes
      .
      • By default, the configuration is
        Enabled
        .
      • Enter a
        Name
         for the TS Agent.
      • Enter the IP address of the Windows
        Host
         on which the TS Agent is installed.
      • Enter the
        Port
         number on which the agent listens for user mapping requests. The port is set to 5009 by default.
      • Save
         your changes.
    • Distribute Identity Data Across Your Prisma Access Environment
      On the
      Identity Redistribution
       dashboard,
      Edit
       the diagram to specify the identity data you want to collect from each source and share across Prisma Access.
    • To activate your changes, push the configuration to Prisma Access.

    NGFWs

    Streamline resource usage by configuring firewalls to collect mapping information from redistribution.
    In a large-scale network, instead of configuring all your firewalls directly to query the mapping information sources, you can streamline resource usage by configuring some firewalls to collect mapping information through redistribution. Data redistribution also provides granularity, allowing you to redistribute only the types of information you specify to only the devices you select. You can also filter the IP user mappings or IP tag mappings using subnets and ranges to ensure the firewalls collect only the mappings they need to enforce policy rules.
    To redistribute the data, you can use the following architecture types:
    • Hub and spoke architecture for a single region:
      To redistribute data between firewalls, use a hub and spoke architecture as a best practice. In this configuration, a hub firewall collects the data from sources such as Windows User-ID agents, syslog servers, Domain Controllers, or other firewalls. Configure the redistribution client firewalls to collect the data from the hub firewall.
    • Multi-Hub and spoke architecture for multiple regions:
      If you have firewalls deployed in multiple regions and want to distribute the data to the firewalls in all of these regions so that you can enforce policy rules consistently regardless of where the user logs in, you can use a multihub and spoke architecture for multiple regions.
    • Hierarchical architecture:
      To redistribute data, you can also use a hierarchical architecture. For example, to redistribute data such as User-ID information, organize the redistribution sequence in layers, where each layer has one or more firewalls. In the bottom layer, PAN-OS integrated User-ID agents running on firewalls and Windows-based User-ID agents running on Windows servers map IP addresses to usernames. Each higher layer has firewalls that receive the mapping information and authentication timestamps from up to 100 redistribution points in the layer beneath it. The top-layer firewalls aggregate the mappings and timestamps from all layers. This deployment provides the option to configure policy rules for all users in top-layer firewalls and region- or function-specific policy rules for a subset of users in the corresponding domains served by lower-layer firewalls.
    When traffic isn’t being enforced as expected, use
    Troubleshooting
     to check the dataplane status of specific firewalls to understand whether there’s a mismatch between expected policies (as configured) and enforced policies.
