Set Up Prisma Access

Provides quick steps to implement Prisma Access
The following sections provide you with the summary steps that you take to install and configure Prisma Access and information about proxy server support between Panorama, Prisma Access, and Cortex Data Lake.

Prisma Access Onboarding and Configuration Workflow

The following workflow provides you with the summary steps that you take to install and configure Prisma Access
If you are setting up a deployment that includes multiple instances of Prisma Access on a single Panorama (multi-tenancy), see Manage Multiple Tenants in Prisma Access. Most organizations do not have a need to create and manage multiple tenants.
  1. Add the following URLs and ports to an allow list on any security appliance that you use with the Panorama appliance that manages Prisma Access.
    In addition, if your Panorama appliance uses a proxy server (
    Panorama
    Setup
    Service
    Proxy Server
    ), or if you use SSL forward proxy with Prisma Access, be sure to add the following URLs and ports to an allow list on the proxy or proxy server.
  2. Add the ports used by Panorama to allow lists in your network.
  3. After you install the Cloud Services plugin, the plugin creates a Panorama administrative user with a username of
    __cloud_services
    . This user account is required to enable communication between Enterprise DLP on Prisma Access and the Prisma Access management infrastructure. Palo Alto Networks recommends that you change the password for this administrative user in accordance with your organization’s password policy.
    If you delete the
    __cloud_services
    user, you must re-add the user manually. The account is used to register and activate Enterprise DLP on Prisma Access, and for continued DLP scanning using the data patterns and data filtering profiles referenced in security policy rules.
  4. Import your existing Panorama configuration to Prisma Access, or create new templates and device groups to begin configuration of Prisma Access.
    In order to push configuration—such as security policy, authentication policy, server profiles, security profiles, address objects, and application groups—to Prisma Access, you must either create new templates and device groups with the configuration settings you want to push to Prisma Access, or leverage your existing device groups and templates by adding them to the template stacks and device group hierarchies that get created when you onboard the service.
    Configuration is simplified in Prisma Access because you do not have to configure any of the infrastructure settings, such as interfaces and routing protocols. This configuration is automated and pushed from Panorama in the templates and device groups that the service creates automatically. You can configure any infrastructure settings that are required by the service, such as settings required to create IPSec VPN tunnels to the IPSec-capable devices at your remote network locations, directly from the plugin. Optionally, you can add templates and device group hierarchies to the configuration to simplify the service setup.
    To simplify the service setup, create or import the templates and device groups you need before you begin the setup tasks for using Prisma Access.
    When creating templates and device groups for Prisma Access, you do not need to assign managed devices to it. Instead, you will add them to the template stacks and device group hierarchies created by the service. Do not add any of the templates or device groups created by Prisma Access to any other template stacks or device groups.
    Also note that some settings that are available in a non-Prisma Access template or device group may not be supported in Prisma Access. See What Features Does Prisma Access Support? for a list of supported features.
  5. Enable the service infrastructure and service connections that allows communication between Prisma Access elements.
    1. Create a service connection to allow access to your corporate resources.
      If you don’t require access to your corporate resources, you should still create a service connection to enable access between mobile users and remote networks.
  6. We recommend using local authentication as a first step to verify that the service is set up and your users have internet access. You can later switch to using your corporate authentication methods.
    1. Configure zones for mobile users.
      1. Create two zones in the Mobile User Template. For example, Mobile-Users and Internet.
      2. Map the zones. You should map any zone that is not Prisma Access connected users or HQ or branch offices to Untrust.
        Under
        Panorama
        Cloud Services
        Configuration
        Mobile Users
        , map Internet to Untrust; Mobile-Users to Trust.
    2. Configure Security policies for the device group.
      To create a Security policy to allow traffic to the Internet, select the Mobile_User_Device_Group
      Policies
      Security
      Prerules
      Add
      a rule. For example: Mobile-Users to Internet.
    3. Commit your changes to get started with the service.
      1. Commit
        locally on Panorama.
      2. Commit and Push
        to Prisma Access.
      3. Select
        Panorama
        Cloud Services
        Status
        Monitor
        Mobile Users
        to view the
        Status
        and verify that you can ping the Portal FQDN.
    4. Validate that Prisma Access is securing Internet traffic for mobile users.
      1. Use the app to connect to the portal as a mobile user (local user).
      2. Browse to a few websites on the internet and check the traffic logs on Panorama.
  7. Plan, create, and configure remote network connections.
    1. Add one or more remote networks to Prisma Access.
      You can onboard one location and then add additional locations using the bulk import capability.
    2. Create a Security policy rule to allow traffic from the remote networks to HQ (For example: Trust to Trust).
    3. Validate the connectivity between the service connection, remote network connection, and mobile users.
  8. You add these addresses to an allow list on your organization’s network to limit inbound access to your enterprise network and applications.
  9. (
    Optional
    ) Change the authentication method from local authentication to your organization’s authentication method.
    1. Create an authentication profile that meets your organization’s requirements (LDAP, RADIUS, etc).
    2. If your organization uses an on-premise authentication server such as RADIUS or Active Directory, add the IP addresses that Prisma Access uses as its source IP address for internal requests () to allow lists in your network, or allow the IP addresses of the entire Infrastructure Subnet (Prisma Access takes the loopback IP address from this subnet).
    3. Update the Authentication Profile for the Prisma Access portal and gateway to use this new authentication profile.
  10. (
    Optional
    ) Forward logs from Cortex Data Lake (formerly Logging Service) to an external Syslog receiver by setting up the Log Forwarding app.

Proxy Support for Prisma Access and Cortex Data Lake

If you have deployed a proxy server between Panorama, the Prisma Access infrastructure, and Cortex Data Lake, refer to the following table for details on the expected behavior:
Functionality
Support through a Proxy Server that does not perform SSL Decryption
Support through a Proxy Server that performs SSL Decryption
Initial onboarding to Cortex Data Lake with Certificate Revocation Status checks using OCSP
Supported
Only pass-through proxies are supported; any proxy using SSL decryption is not supported.
Panorama Queries to Cortex Data Lake for Reports and Logs
If the proxy server is the default route on Panorama, you cannot view the data on the ACC and
Monitor
Logs
pages.
You can view data on the ACC and
Monitor
Logs
pages if Panorama has an alternate route to the Cortex Data Lake and you can bypass the proxy server.
