Subscribing to Live Resources

This describes subscriptions in Live.

Threats and the corporate landscape change over time. NetWitness periodically reviews existing content to determine whether it needs to be updated based upon current campaigns, or has become irrelevant due to changes in technology or attack techniques and tools.

You can discover new content by using the What’s New dashlet within the Default Dashboard, or by searching through NetWitness Live by data range since last deployed. Be sure to subscribe to any content for which you want to receive update notifications.

Subscription Updates

When you view resources in the Matching Resources panel of the Live Content view, there is a column named Updated:

This value is also displayed when you select the detailed view for a resource. Every time a resource changes, its Updated value changes to match the specific update. If you are subscribed to a resource, and it gets updated, your system is automatically updated with the latest version, and you receive a notification. You can view your notifications by clicking the Notification icon, netwitness_ic-notifbell_22x22.png, from anywhere in the NetWitness UI.

You can also get email notifications when subscribed resources are updated. System Administrators can add email addresses in the netwitness_adminicon_25x22.png (Admin) > SYSTEM > Live Services view. For more information, see the "Live Services Configuration Panel" topic in the System Configuration Guide.

Adding Subscribed Resources for Deployment to Services

  1. Go to netwitness_configureicon_24x21.png (Configure) > Subscriptions > Deployments.
  2. In the Groups panel, select a group.
    Subscribed resources, if any, are listed in the Deployments tab Subscriptions panel.

    The Add Subscription dialog, which lists subscriptions available for deployment, is displayed.

  4. Select the subscribed resources that you want to deploy to the services group.

    The dialog closes and the subscriptions are added to the listing in the Deployments tab, Subscriptions panel. This stages the resources for deployment at the next synchronization.

  6. You can click the Synchronize icon, netwitness_synchronizeicon.png, to immediately synchronize your changes.

Deleting a Subscription

When you delete a subscription to a resource, deployed instances of the resource are not deleted. The deployed resource remains on services until explicitly removed, but the resource is no longer synchronized with the resource in NetWitness Live.

To delete a subscription:

  1. Go to netwitness_configureicon_24x21.png (Configure) > Subscriptions.
  2. In the Subscriptions tab, select the subscriptions you want to delete.

    Your selected subscriptions are deleted from the subscriptions list, but any deployed instances of the subscribed resource remain on the services.

Removing Subscribed Resources from the Deployments Subscriptions Grid

Subscriptions that are selected for deployment to a service group are deployed during synchronization. You can remove subscriptions from the Live netwitness_configureicon_24x21.png (Configure) > Subscriptions > Deployments panel, but any that have actually been deployed to services remain deployed until someone removes them.

To remove resources from the Deployments tab Subscriptions panel:

  1. Go to netwitness_configureicon_24x21.png (Configure) > Subscriptions > Deployments

    Subscribed resources, if any, are listed in the Subscriptions panel.

  3. In the Subscriptions panel, click netwitness_delete.png.

    A dialog requests confirmation that you want to delete the resource from the service group. The resource is removed from the Deployments tab Subscriptions panel, but is not removed from services on which it is deployed.
