Impact requirements

Review the requirements before you install and use Impact.

Core platform dependencies

Make sure that your environment meets the following requirements:

Tanium license that includes Impact

Impact is no longer included as part of the Tanium Core Platform and now requires a license. All existing Impact customers can continue to use Impact for free.
Tanium™ Core Platform servers: 7.5.4.1158 or later
Tanium™ Client: Any supported version of Tanium Client. For the Tanium Client versions supported for each OS, see Tanium Client Management User Guide: Client version and host system requirements.
If you use a client version that is not listed, certain product features might not be available, or stability issues can occur that can only be resolved by upgrading to one of the listed client versions.

Solution dependencies

Other Tanium solutions are required for Impact to function (required dependencies) or for specific Impact features to work (feature-specific dependencies). The installation method that you select determines if the Tanium Server automatically imports dependencies or if you must manually import them.

Some Impact dependencies have their own dependencies, which you can see by clicking the links in the lists of Required dependencies and Feature-specific dependencies. Note that the links open the user guides for the latest version of each solution, not necessarily the minimum version that Impact requires.

Tanium recommended installation

If you select Tanium Recommended Installation when you import Impact, the Tanium Server automatically imports all your licensed solutions at the same time. See Tanium Console User Guide: Import all modules and services.

Import specific solutions

If you select only Impact to import and are using Tanium Core Platform 7.5.2.3531 with Tanium Console 3.0.72 or later, the Tanium Server automatically imports the latest available versions of any required dependencies that are missing. If some required dependencies are already imported but their versions are earlier than the minimum required for Impact, the server automatically updates those dependencies to the latest available versions.

If you select only Impact to import and you are using Tanium Core Platform 7.5.2.3503 or earlier with Tanium Console 3.0.64 or earlier, you must manually import or update required dependencies. See Tanium Console User Guide: Import, re-import, or update specific solutions.

Required dependencies

Impact has the following required dependencies at the specified minimum versions. You must install the dependencies in the listed order.

Tanium™ Interact 2.2.3 or later
Tanium™ System User Service 1.0.77 or later
Tanium™ RDB Service 1.2.31 or later
Tanium™ Directory Query 1.0 or later
Tanium™ Criticality 1.1 or later
Tanium™ Endpoint Configuration 1.2 or later (installed as part of Tanium™ Client Management 1.5 or later)

Feature-specific dependencies

Impact has the following feature-specific dependencies at the specified minimum versions:

Tanium Connect 5.8.54 or later is required to send Impact data to destinations.
Tanium Threat Response 2.5.1 or later is required to display Impact ratings for alerts in Threat Response.
Tanium Trends 3.6.323 or later is required to view the Impact Trends board.

Client extensions

Tanium Endpoint Configuration installs client extensions for Impact on endpoints. Client Extensions perform tasks that are common to certain Tanium solutions. The Tanium Client uses code signatures to verify the integrity of each client extension prior to loading the extension on the endpoint. Each client extension has recommended security exclusions to allow the Tanium processes to run without interference. See Security exclusions for more information. The following client extensions perform Impact functions:

Config CX - Provides installation and configuration of extensions on endpoints. Tanium Client Management installs this client extension.
Core CX - Provides a management framework API for all other client extensions and exposes operating system metrics. Tanium Client Management installs this client extension.
DEC CX - Provides a direct connection between endpoint and Module ServerTanium Cloud. Tanium Direct Connect installs this client extension. This is a feature-specific dependency for Impact satellite synchronization.

Tanium™ Module Server

Impact is installed and runs as a service on the Module Server host computer. The impact on the Module Server is minimal and depends on usage.

For information about Module Server sizing in a Windows deployment, see Tanium Core Platform Deployment Guide for Windows: Host system sizing guidelines.

Endpoints

Supported operating systems

The following endpoint operating systems are supported with Impact.

Operating system	OS version	Notes
Microsoft Windows Server	Microsoft Windows Server 2008 R2 (SP1) and later	Windows Server 2008 R2 SP1 requires Microsoft KB2758857.
Microsoft Windows Workstation	Microsoft Windows 7 (SP1) and later	Windows 7 Service Pack 1 requires Microsoft KB2758857.

Host and network security requirements

Specific ports and processes are needed to run Impact.

Ports

The following ports are required for Impact communication.

Source	Destination	Port	Protocol	Purpose
Module Server Tanium Cloud or satellite	Active Directory Server	389 / 636	LDAP / LDAPS	Connecting to the Active Directory server.
Module Server Tanium Cloud or satellite	Active Directory Global Catalog Server	3268 / 3269	LDAP / LDAPS	Required only when connecting to the Active Directory Global Catalog server. For more information, see Configure connections to domains Configure connections to domains.

Configure firewall policies to open ports for Tanium traffic with TCP-based rules instead of application identity-based rules. For example, on a Palo Alto Networks firewall, configure the rules with service objects or service groups instead of application objects or application groups.

For Tanium Cloud ports, see Tanium Cloud Deployment Guide: Host and network security requirements.

Security exclusions

If security software is in use in the environment to monitor and block unknown host system processes, Tanium recommends that a security administrator create exclusions to allow the Tanium processes to run without interference. The configuration of these exclusions varies depending on AV software. For a list of all security exclusions to define across Tanium, see Tanium Core Platform Deployment Reference Guide: Host system security exclusions.

User role requirements

The following tables list the role permissions required to use Impact. To review a summary of the predefined roles, see Set up Impact users.
