    About this task

    Activating EKMS installs the necessary components to encrypt ServiceNow data with external keys managed in AWS Key Management Service.

    Procedure

    1. Navigate to All > System Definition > Plugins.
    2. Under Search your licensed applications and plugins, search for Platform Encryption External Key Management.

      The search should reveal the plugin. If you purchase a subscription for External Key Management Service through either Platform Encryption or ServiceNow Vault, you can also see this plugin available.

      Important:
      To activate the External Key Management Service, you must first purchase a subscription to either Platform Encryption or ServiceNow Vault and ensure the dependent plugin is installed: Key Management Framework Scoped App.
    3. Select Install
      Note:
      When domain separation and delegated admin are enabled in an instance, the administrative user must be in the global domain. Otherwise, the following error appears: Application installation is unavailable because another operation is running: Plugin Activation for <plugin name>.

    Result

    The EKMS plugin is now installed and activated. You can proceed to configure your external key integration.
