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:
The following modules are optional:
|
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. |

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 |
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.
| Target Device | Notes | Process |
|---|---|---|
| Module Server | <Module Server>\services\discover-service\node.exe | |
| <Module Server>\plugins\content\discover-proxy\proxyplugin.exe | ||
| <Module Server>\services\twsm-v1\twsm.exe | ||
| <Module Server>\services\endpoint-configuration-service\TaniumEndpointConfigService.exe | ||
| Windows endpoints | (Level 3 and 4 profiles only) | C:\Program Files\Npcap |
| (Level 3 and 4 profiles only) | <Tanium Client>\Tools\Discover\nmap\nmap.exe | |
| Linux endpoints | (Level 3 and 4 profiles only) |
<Tanium Client>/Tools/Discover/nmap/nmap |
| macOS endpoints | (Level 3 and 4 profiles only) | <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:
-
content.tanium.com
-
ec2.*.amazonaws.com, sts.*.amazonaws.com, and ssm.*.amazonaws.com (for centralized scans of Amazon EC2 environments)
