    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.
    To strengthen your security posture, configuring a unique master key for Panorama and for each managed firewall. By configuring unique master keys, you can ensure that a compromised master key does not compromise the configuration encryption of your entire deployment. Unique master keys are supported only for Panorama and managed firewalls. Log Collectors and WildFire appliances must share the same master key as Panorama. For Panorama or managed firewalls in a high availability (HA) configuration, you must deploy the same master key for both HA peers as the master key is not synchronized across HA peers.
    The default encryption algorithm that the master key uses to encrypt data is AES-256-CBC—the same algorithm that the master key used prior to PAN-OS 10.0. AES-256-CBC is the default encryption level because when you manage firewalls with Panorama, the managed firewalls may be on different PAN-OS releases, and firewalls on PAN-OS releases earlier than PAN-OS 10.0 do not support AES-256-GCM. This is why Panorama must use the lowest level of encryption that its managed devices can use. For example, if some managed devices run PAN-OS 10.0 and some run earlier versions, Panorama must use AES-256-CBC. However, if all managed devices run PAN-OS 10.0 or later, then Panorama and all of its managed devices can use AES-256-GCM.
    Palo Alto Networks recommends using AES 256-GCM level 2 for master key encryption.
    Configuring a unique master key also eases the operational burden of updating your master keys. By configuring a unique master key for a managed firewall, you can update each master key individually without the need to coordinate changing the master key across a large number of managed firewalls.
    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 a unique master key for a managed firewall.
      1. (HA only) Disable Config Sync for managed firewalls.
        This step is required before deploying a new master key to a firewall HA pair
        1. Log in to the Panorama Web Interface.

      2. Select PanoramaManaged DevicesSummary and Deploy Master Key.
      3. Select a managed firewall and Change the master key.
        If you want to deploy a unique master key for a specific set of managed firewalls, you can select those specific managed firewalls as well.
      4. Configure the master key:
        1. If renewing a master key, enter the Current Master Key. If you are replacing the default master key with a new master key, do not specify a Current Master Key.
        2. (Optional) Enable (check) Stored on HSM if the master key is encrypted on a Hardware Security Module (HSM).
        3. Specify the New Master Key and Confirm Master Key.
        4. Configure the master key Lifetime and Time for Reminder.
        5. Click OK.
          The new master key is automatically pushed to your managed firewalls after you click OK. Proceed only if you are certain you are ready to change the master key for your managed firewalls.
      5. Verify that the master key was deployed successfully to all selected managed firewalls.
        A System log generates when you deploy a new master key from Panorama.
      6. (Optional) Configure the master key to automatically renew for your managed firewalls.
        Configure this setting to automatically renew the master key deployed on the managed firewalls associated with the selected template. Otherwise, the master key expires per the configured master key lifetime and you must deploy a new master key.
        1. Select DeviceMaster Key and Diagnostic and select the Template containing the target managed firewalls.
        2. Edit the Master Key settings and configure the Auto Renew With Same Master Key setting.
        3. Click OK.
