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

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 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.
Tanium solutions	If you selected Tanium Recommended Installation when you installed Discover, the Tanium Server automatically installed all your licensed solutions at the same time. Otherwise, you must manually install the solutions that Discover requires to function, as described in Tanium Console User Guide: Import, re-import, or update specific solutions. Discover requires the following solutions: Tanium Client Management 1.7.0 or later Tanium Endpoint Configuration 1.2 or later Endpoint Configuration is installed as part of Tanium Client Management 1.5 or later.

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 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.

Tanium solutions

If you selected Tanium Recommended Installation when you installed Discover, the Tanium Server automatically installed all your licensed solutions at the same time. Otherwise, you must manually install the solutions that Discover requires to function, as described in Tanium Console User Guide: Import, re-import, or update specific solutions.

Discover requires the following solutions:

Tanium Client Management 1.7.0 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 solutions are optional:

Tanium Interact 2.8 or later (promote data to Tanium Data Service)
Tanium Trends 3.6 or later (create charts on Discover Overview page)
Tanium Connect 5.0 or later (export Discover data)

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 internet protocols

Discover currently scans only for IPv4 addresses.

Supported operating systems

For Tanium Client operating system support, see Tanium Client Management User Guide: Client version and 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 Management User Guide: Deploy the Tanium Client to AIX endpoints using a package file.

Supported platforms per discovery method
	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 and protocols 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

Scan communication requirements

The following ports and protocols are required for Discover scanning.

Source	Destination	Scan Type	Port	Protocol	Purpose
Tanium Client	Devices with an IP address in the same subnet as the Tanium Client	Level 2 distributed	N/A	ICMP	Level 2 distributed scans require ICMP echo-request and echo-response traffic from all managed endpoints to all other devices on the Tanium Client subnet.
		Level 3	N/A	ARP	Level 3 distributed scans require ARP-request traffic from the managed endpoint on the Tanium Client subnet.
		Level 4 distributed	1000 most common TCP ports (default setting)	ARP TCP	Level 4 distributed scans require ARP-request traffic from the managed endpoint on the Tanium Client subnet. Additionally, by default, Discover scans the 1000 most commonly used TCP ports on the Tanium Client subnet to calculate the OS Generation field. You can change this setting in the scan profile. For more information, see Running distributed scans.
Module Server	Customer-defined subnets	Centralized Nmap	N/A	ICMP	Centralized Nmap scans require ICMP traffic to all IP addresses specified in the scan.
	Customer-defined subnets	Centralized Nmap	1000 most common open TCP ports (default setting)	TCMP	For centralized Nmap scans, by default, Discover scans the 1000 most commonly used TCP ports on the Tanium Client subnet to calculate the OS Generation field. You can change this setting in the scan profile. For more information, see Running centralized scans.
	ec2..amazonaws.com sts..amazonaws.com ssm.*.amazonaws.com	Centralized Amazon EC2 environment	443	TCP	Centralized Amazon EC2 environment scans require access to Amazon Web Services.

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.

Discover security exclusions
Target Device	Notes	Exclusion Type	Exclusion
Module Server		Process	<Module Server>\services\discover-service\node.exe
		Process	<Module Server>\plugins\content\discover-proxy\proxyplugin.exe
		Process	<Module Server>\services\twsm-v1\twsm.exe
		Process	<Module Server>\services\endpoint-configuration-service\TaniumEndpointConfigService.exe
Windows endpoints	(Level 3 and 4 profiles only)	Folder	C:\Program Files\Npcap
Windows endpoints	(Level 3 and 4 profiles only)	Process	<Tanium Client>\Tools\Discover\nmap\nmap.exe
Linux endpoints	(Level 3 and 4 profiles only)	Process	<Tanium Client>/Tools/Discover/nmap/nmap
macOS endpoints	(Level 3 and 4 profiles only)	Process	<Tanium Client>/Tools/Discover/nmap/nmap

Internet URLs

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

From both Tanium Server and Tanium Module Server: content.tanium.com
From Tanium Module Server: ec2.*.amazonaws.com, sts.*.amazonaws.com, and ssm.*.amazonaws.com (for centralized scans of Amazon EC2 environments)
