    Manage the Master Key from Panorama

    Deploy new, or renew expiring master keys, to firewalls, log collectors, and WF-500 appliances from the Panorama™ management server.
    Panorama, firewalls, Log Collectors, and WF-500 appliances use a master key to encrypt sensitive elements in the configuration and they have a default master key they use to encrypt passwords and configuration elements.
    As part of a standard security practice, you should replace the default master key and change the key on each individual firewall, Log Collector, WildFire appliance, and Panorama before it expires. You must deploy the same master key to all of your managed devices and you must configure the master key on Panorama to successfully push the configuration from Panorama to your managed devices. To ensure a uniform key deployment, deploy a new master key or renew an expiring master key on multiple firewalls, Log Collectors, and WF-500 appliances directly from Panorama. See Configure the Master Key for more information on configuring a master key.
    To update the master key for managed firewalls from Panorama, the configuration pushed from Panorama and the local firewall configuration must not contain any cross references to each other in their configuration objects.
    In this procedure, you must contact Palo Alto Networks Support to push the Panorama configuration back to managed firewalls for which you localized the configuration and ensure you have a complete list of all local overrides on your managed firewalls. Failure to preserve important local firewall configurations or restore any local overrides or references can result in network disruptions.
    Palo Alto Networks recommends updating the master key from Panorama during a planned maintenance window and with the help of Palo Alto Networks Support to avoid network disruptions for your organization.
    If your managed firewalls contain both local and Panorama pushed configuration that reference one another, you are required to either localize the configuration to the firewall. This removes any local overrides of a Panorama pushed configuration which may lead to network disruptions if not restored correctly.
    For managed firewalls in a high availability (HA) configuration, you are required to disable HA as well.
    When a master key expires, you must enter the current master key in order to configure a new master key.
    Be sure to keep track of the master key you deploy to your managed firewalls, Log Collectors, and WildFire appliances because master keys cannot be recovered. you must reset to factory default if you cannot provide the current master key when it expires.
    1. Log in to the Panorama Web Interface.
    2. (Best Practice) Select Commit and Commit and Push any pending configuration changes.
      Panorama must re-encrypt data using the new master key. To ensure all configuration elements are encrypted with the new master key, you should commit all pending changes before deploying the new master key.
    3. Configure the firewall, Log Collector, and WildFire appliance master key to automatically renew with the same master key after the lifetime of the key expires.
      Automatically renewing the master key allows you to keep your configuration encrypted in the event the key expires before a maintenance window but this is not a replacement for deploying a new master key after the key lifetime expires. Consider the number of days until your next available maintenance window when configuring the master key to automatically renew when the lifetime of the key expires.
      1. Select DeviceMaster Key and Diagnostics and select the template containing the managed firewall, Log Collector, or WildFire master key configuration settings.
      2. Edit the Master Key setting.
      3. Configure Panorama to Auto Renew with Same Master Key for a specified number of days or hours.
    4. Localize the managed firewall configuration.
      This step is required only if the managed firewall has a local and Panorama pushed configuration that reference each other or local overrides of a Panorama pushed configuration.
      Skip this step if your managed firewall configuration is entirely pushed from Panorama, or if the managed firewall configuration contains both a local and Panorama pushed configuration contains no references to each other or local overrides.
      1. Log in to the firewall web interface.
      2. Locate and document all local overrides of the Panorama pushed configuration.
        This step is required when you restore configuration objects pushed from Panorama to the managed firewall configuration. Localizing the managed firewall configuration removes all local overrides and converts them into local configuration objects. When you restore the managed firewall configuration, these objects may be overridden with a Panorama pushed configuration objects of the same name and not have the firewall specific values.
      3. Select DeviceSetupManagement and edit the Panorama Settings.
      4. Disable Panorama Policy and Objects and Import Panorama Policy and Objects before disabling.
        Import Panorama Policy and Objects before disabling to import the Panorama pushed policy and device group objects to the local firewall configuration. Otherwise, the firewall deletes these Panorama pushed policy and device settings from the managed firewall.
      5. Click OK.
      6. Disable Device and Network Templates and Import Device and Network Templates before disabling.
        Import Device and Network Templates before disabling to import the Panorama pushed device and template objects to the local firewall configuration. Otherwise, the firewall deletes these Panorama pushed device and template settings from the managed firewall.
      7. Click OK.
      8. Commit.
    5. Deploy the master key to managed firewalls.
      1. (HA only) Disable Config Sync for managed firewalls.
