Incident Response requirements

Review the requirements before you install and use Incident Response.

Tanium dependencies

Component	Requirement
Platform	Version 7.2 or later.
Tanium Client	Version 6.0.314.1396 or later.
License	For information about licensing Incident Response, contact your Technical Account Manager (TAM). The license for Incident Response includes the following solutions: Tanium Incident Response Tanium Quarantine (Quarantine) Tanium Live Response (Live Response) Tanium Index (Index) Windows Security Patch Management (for more information, see Tanium Knowledge Base)
Tanium™ Trace	Version 2.3.2.0004 or later is required for real-time events on Linux endpoints with Tanium Index 2.0.0 or later.

Third-party software requirements

For Tanium Incident Response, the required third-party software is installed automatically.

However, the IR Gatherer solution has third-party software requirements that are not installed automatically. The related documentation includes instructions to download the software and include it in packages that are distributed to the endpoints.

Endpoints

Supported operating systems

The following endpoint operating systems are supported by Incident Response, Copy tools, Quarantine, Index, and Live Response:

• Windows (A minimum of Windows 7 or Windows Server 2008 R2 with SP1 is required. Windows 7 Service Pack 1 requires Microsoft KB2758857.)
• macOS (macOS 10.14 (Mojave) or later is required for Tanium Incident Response 4.5.3 or later and Tanium Index 2.3.2 or later)
• Linux

See the documentation for each IR solution for specific version numbers.

Disk space requirements

Index requires 1 GB free space. For other solutions, the required disk space is minimal.

Host and network security requirements

Specific ports and processes are needed to run Incident Response.

Ports

The following ports are required for IR communication.

IR Solution	Port	Direction	Purpose
Live Response	443 (S3), 22 (SFTP/SCP), or 445 (SMB)	Outbound	Outbound connections over ports depending on how the collected data is being transferred.

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.

Security exclusions

If security software is in use in the environment to monitor and block unknown host system processes, your security administrator must create exclusions to allow the Tanium processes to run without interference.
