Discover requirements

Review the requirements before you use Discover.

Also review the Tanium as a Service requirements, described in Tanium as a Service User Guide: Tanium as a Service requirements.

Tanium dependencies

In addition to a license for the Discover product module, make sure that your environment also meets the following requirements.

Component Requirement
Tanium™ Core Platform

Version 7.3.314.4250 or later

Tanium™ Client Any supported version of Tanium Client. For the Tanium Client versions supported for each OS, see Tanium Client 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.
Tanium Products

If you clicked the Install with Recommended Configurations button when you installed Discover, the Tanium Server automatically installed all your licensed modules at the same time. Otherwise, you must manually install the modules that Discover requires to function, as described under Tanium Console User Guide: Manage Tanium modules.

Discover requires the following modules:

  • Tanium Interact 2.4.50 or later

  • Tanium Endpoint Configuration 1.2 or later

    Endpoint Configuration is installed as part of Tanium Client Management 1.5 or later.

The following modules are optional:

  • Tanium Trends 3.6 or later (create charts on Discover Overview page)
  • Tanium Connect 5.0 or later (export Discover data)
  • Tanium Network Quarantine 1.0.2 or later (block networks)

Tanium™ Module Server

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

For more information, see Tanium Core Platform Installation Guide: Host system sizing guidelines.

Endpoints

Supported operating systems

For Tanium Client operating system support, see Tanium Client User Guide: Host system requirements. Managed endpoints perform discovery scans.

Operating System Version
Windows

Windows 7 SP1 or later and Windows Server 2008 R2 SP1 or later

If the endpoints are not up-to-date and Python content does not run and generates an error about nt._add_dll_directory with The specified procedure could not be found, see this Microsoft Security Advisory.
macOS 10.11 and later
Linux

Same as Tanium Client support
Solaris

Same as Tanium Client support
AIX

7.1.4 or later

The IBM XL C++ runtime libraries file set (xlC.rte), version 16.1.0.0 or later, and the IBM LLVM runtime libraries file set (libc++.rte) must be installed. For installation instructions, see Tanium Client User Guide: Deploying the Tanium Client to AIX endpoints.

 

Table 1:   Supported platforms per discovery method
  Level 1 (ARP cache) Level 1  (Interface Connections) Level 2 (Ping) Level 3/4 (Nmap)
Windows 1
Linux
macOS
Solaris 3 2
AIX 2

1 For level 3 and 4 discovery on Windows 2003 Server and Windows XP, level 2 discovery is used.

2 For level 3 and 4 discovery on Solaris and AIX, level 2 discovery is used because Nmap is not supported on these platforms.

3 Solaris endpoints do not perform OS detection.

Host and network security requirements

Specific ports and processes are needed to run Discover.

Ports

For Tanium as a Service ports, see Tanium as a Service User Guide: Host and network security requirements.

The following ports are required for Discover communication.

Source Destination Port Protocol Purpose

Module Server

 Module Server 17446 TCP and UDP Internal purposes for Discover; not externally accessible
Module Server 17447 TCP and UDP Internal purposes for Discover; not externally accessible

ec2.*.amazonaws.com

sts.*.amazonaws.com

ssm.*.amazonaws.com

 443 TCP Access to Amazon Web Services for Discover centralized Amazon EC2 environment scans
Endpoints Top 1,000 TCP and UDP ports (nmap default) TCP and UDP OS fingerprinting for Discover centralized Nmap scans

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. For a list of all security exclusions to define across Tanium, see Tanium Core Platform Deployment Reference Guide: Host system security exclusions.

Internet URLs

If security software is deployed in the environment to monitor and block unknown URLs, your security administrator must allow the following URLs:

  • content.tanium.com

  • ec2.*.amazonaws.com, sts.*.amazonaws.com, and ssm.*.amazonaws.com (for centralized scans of Amazon EC2 environments)
