About Splunk Phantom

Splunk Phantom is a world-class Security Orchestration, Automation, and Response (SOAR) system. The Splunk Phantom platform combines security infrastructure orchestration, playbook automation and case management capabilities to integrate your team, processes, and tools together.

The diagram shows the end-to-end flow of security automation in Splunk Phantom.

This screen image shows a flowchart of the main components in Splunk Phantom. The elements are described in the table immediately following the image.

The main components of Splunk Phantom each play a role in delivering end-to-end security automation.

Component Description
App An App extends the Splunk Phantom platform by adding connectivity to third party security technologies. The connections allow Splunk Phantom to access and run actions that are provided the third party technologies. Some apps may also provide a visual component such as widgets that can be used to render data produced by the app.

This example shows three apps in a Splunk Phantom environment and the actions provided by each app:

  • The MaxMind app provides an action to find the geographical location of an IP address.
  • The PhishTank app provides an action to find the reputation of a URL.
  • The Palo Alto Networks (PAN) Firewall app provides several actions, such as blocking and unblocking access to IP addresses, applications, and URLs.

See Add and configure apps and assets to provide actions in Splunk Phantom in Administer Splunk Phantom.

Asset An Asset is a specific instance of an app. Each asset represents a physical or virtual device within your organization such as a server, endpoint, router, or firewall. For example, you have a Palo Alto Network (PAN) firewall app that connects the firewall to Splunk Phantom. Then, you configure an asset with the specific connection details to a specific firewall. If your environment has multiple firewalls, you can configure one asset for each firewall.

Assets must be configured within Splunk Phantom in order to automate actions on them. Assets typically also possess primary and secondary owners.

This example shows one MaxMind asset, one PhishTank asset, and two PAN firewall assets. The PAN assets have different version numbers, which is the reason for having two assets.

See Add and configure apps and assets to provide actions in Splunk Phantom in Administer Splunk Phantom.

Container A container is a security event that is ingested into Splunk Phantom.

Containers have the default label of Events. Labels are used to group related containers together. For example, containers from the same asset can all have the same label. You can then run a playbook against all containers with the same label.

You can create custom labels in Splunk Phantom as needed. See Configure labels to apply to containers.

Case A case is a special kind of container that can hold other containers. For example, if you have several closely related containers for a security incident, you can promote one of those containers to a case and then add the other related containers to the case. Doing this enables you to consolidate your investigation rather than having to investigate each container individually.

See Overview of cases.

Artifact An artifact is a piece of information added to a container, such as a file hash, IP address, or email header.
Indicator, or Indicator of Compromise (IOC) An indicator is a piece of data such as an IP address, host name, or file hash that populates the Common Event Format (CEF) fields in an artifact. Indicators are the smallest unit of data that can be acted upon in Splunk Phantom.
Playbook A Playbook defines a series of automation tasks that act on new data entering Splunk Phantom. For example, you configure a playbook to run specific against all new containers with a specific label. Or, you can configure running a playbook as part of the workflow in a workbook.

In this example, two playbooks are configured:

  • Playbook 1 runs the following actions whenever a new container is created in Splunk Phantom:
    • The geolocate ip action, using the MaxMind asset.
    • The block ip action, using the version 2.7 PAN Firewall asset
  • Playbook 2 runs the following actions whenever a specific workbook is used in a case:
    • The url reputation action from the PhishTank asset.
    • The list application, unblock application, and unblock URL actions using the version 3.0 PAN Firewall asset.

See Create playbooks to automate analyst workflows in Splunk Phantom.

Workbook A workbook is a template providing a list of standard tasks that analysts can follow when evaluating containers or cases.

See Define a workflow in a case using workbooks in Splunk Phantom.

Action An Action is a high level primitive used throughout the Splunk Phantom platform, such as get process dump, block ip, suspend vm, or terminate process. Actions are run in playbooks or manually from the Splunk Phantom web interface.

Actions are made available to Splunk Phantom by apps. See Add and configure apps and assets to provide actions in Splunk Phantom in Administer Splunk Phantom.

Owner An Owner is responsible managing assets in your organization. Owners receive approvals, which are requests to execute a particular action on a particular asset. Approvals are sent to the asset owners and contain a service level agreement (SLA) dictating the expected response time. Approvals are first sent to the primary asset owners. If the SLA is breached, then the approval is redirected to the secondary asset owner. SLAs can be set on events, phases, and tasks.
