Splunk® Phantom (Legacy)

Use Splunk Phantom

Splunk Phantom 4.10.7 is the final release of Splunk's Security Orchestration, Automation, and Response (SOAR) system to be called Splunk Phantom. All later versions are named Splunk SOAR (On-premises). For more information, see the Splunk SOAR (On-premises) documentation.

About Splunk Phantom

Splunk Phantom is a 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 to help you orchestrate security workflows, automate repetitive security tasks, and quickly respond to threats.

This diagram shows the end-to-end flow of security automation in Splunk Phantom. See the table immediately following the diagram for more information about each Splunk Phantom component in the diagram.

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

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

The diagram shows three apps in a Splunk Phantom environment:

  • 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 the Administer Splunk Phantom manual.

Asset 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 might have a Palo Alto Network (PAN) firewall app that connects the firewall to Splunk Phantom. You can configure an asset with the specific connection details for this firewall. If your environment has multiple firewalls, you can configure one asset for each firewall.

The diagram 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 the Administer Splunk Phantom manual.

Container 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 in the Administer Splunk Phantom manual.

Case 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 lets you consolidate your investigation rather than having to investigate each container individually.

See Overview of cases.

Artifact A piece of information added to a container, such as a file hash, IP address, or email header.
Indicator or Indicator of Compromise (IOC) 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 Defines a series of automation tasks that act on new data entering Splunk Phantom. For example, you can configure a playbook to run actions against all new containers with a specific label. Or you can configure running a playbook as part of the workflow in a workbook.

In the diagram, two playbooks are configured:

  • Playbook 1 runs actions from the MaxMind and PAN Firewall version 2.7 assets whenever a new container is created in Splunk Phantom.
  • Playbook 2 runs actions from the PhishTank and PAN Firewall version 3.0 assets whenever a specific workbook is used in a case.

See Use playbooks to automate analyst workflows in Splunk Phantom in the Build Playbooks with the Visual Editor manual.

Workbook 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 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 the Administer Splunk Phantom manual.

Owner The person responsible for managing assets in your organization. Owners receive approvals, which are requests to run a particular action on an asset. Approvals are sent to the asset owners and contain a service level agreement (SLA) dictating the expected response time. SLAs can be set on events, phases, and tasks.
