Tanium Core Platform server settings

You configure the host system settings of most Tanium Core Platform servers during installation. When troubleshooting an issue, your Tanium Technical Account Manger (TAM) or Tanium Support might ask you to review or confirm these settings, but rarely ask you to change them. If a TAM does ask you to change settings, you can change many of them through the Tanium Console in Tanium Core Platform 7.4 or later (see Tanium Console User Guide: Managing Tanium Server (local) settings). The following sections describe how to configure the settings through means other than the console.

Settings specified during installation are saved in the configuration database. You can use TanOS menus to add, delete, or modify settings as directed by your TAM.

  1. Log into the TanOS console as the user tanadmin.
  2. Enter 2 to go to the Tanium Operations menu.
  3. Enter 2 to go to the Tanium Configuration Settings menu.
  4. Use the menu to view and edit Tanium component server settings.

Tanium Server

Settings Guidelines
AddressMask Hexadecimal value of a subnet CIDR that delineates the clients that belong to a chain.

Do not change this setting unless instructed to do so by your TAM.
AllowedHubs The Zone Server Hub that is allowed to connect to this Tanium Server. The Zone Server Hub is collocated on the Tanium Server appliance and this setting has the value 127.0.0.1.
AuthPluginTimeoutSeconds The default is 60.
AuthenticationPlugin String that specifies the pluggable authentication module (PAM).
ConsoleSettingsJSON Path to the console settings file.
LogPath The default is /opt/Tanium/TaniumServer/Logs.
LogVerbosityLevel Log verbosity level:
  • 0: Logging disabled.
  • 1: Normal log level.
  • 41: Recommended during troubleshooting.
  • >= 91: Most detailed log level. Enable for short periods of time only.
ModuleServer Module Server IP address.
ModuleServerPort Module Server port. The default is 17477.
PKIDatabasePassword You must manually add this setting to prevent unauthorized access to the pki.db file, which contains the Tanium Server root keys, message-signing keys, and TLS keys. Set the Value Type to protected and specify a password to encrypt the pki.db file. The file is in the Tanium Server installation folder and a copy resides in the /backups subfolder. For details about these keys, see Tanium Console User Guide: Managing Tanium keys.
ReportingTLSCertPath Setting for inbound connections. Path to the TLS certificate that was created upon installation. This certificate is used in TLS connections initiated by the Tanium Client, the Tanium Zone Server Hub, or the Tanium Zone Server.
ReportingTLSKeyPath Setting for inbound connections. Path to the private key file used in TLS connections. This setting must be present to enable TLS.
ReportingTLSMode Configures TLS for outgoing connections that the server initiates. On a Tanium Server, configure this option if you want to enable TLS for the Tanium Server to Zone Server Hub segment, if the Zone Server Hub is not collocated on the Tanium Server. Otherwise, this setting does not apply to a Tanium Server appliance role, which uses IPSec instead of TLS to secure the Tanium Server Active-Active cluster communication.
  • 0 (TLS not used)
  • 1 (TLS required)
  • 2 (TLS optional)
RequireIncomingEncryption Setting for inbound connections. Implicitly set to 0 by default. To set a different value, you must add the setting.
  • 0 (TLS not required)
  • 1 (TLS required)

Important: When RequireIncomingEncryption is set to 1, only TLS connection requests are processed, so only Tanium Clients that have TLS enabled are able to register and be managed. Do not set this to 1 until you are sure all Tanium Clients that have been deployed are configured to use TLS (ReportingTLSMode=1 or ReportingTLSMode=2), and you are ready to deploy Tanium Client to new endpoints with TLS configured prior to initial registration. Do not set this to 1 if your deployment has Tanium Client 6.0, which does not support TLS.
ServerPort Tanium Server port. The server listens for Tanium Clients on this port. The default is 17472. Do not change the ServerPort setting in the TaniumServer.ini configuration file; instead, use the Tanium Operations > Change Tanium Port menu.
ServerSOAPPort Tanium Console and SOAP API port. The default is 8443. Port 443 redirects to this 8443.
SQLConnectionString Database server connection information. The following are examples:

For PostgreSQL, see the PostgreSQL documentation for the supported keywords, such as dbname, port, and user.

If you change this setting, you must restart the Tanium Server.
SSLCipherSuite ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA256:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK
SSLHonorCipherOrder The default is 1.
TrustedCertPath Path to the certificate file used for secure connections to the Tanium Console port.
Version Tanium Server version number.

Tanium Server TDownloader

Settings Guidelines
BypassCRLCheckHostList Use this setting to list servers that the Tanium Server can trust without checking a certificate revocation list (CRL). The Tanium Server performs a CRL check on all servers that are not in this list, and does not download files from a server that fails the check. Specify the servers by FQDN or IP address. You must enter IPv6 addresses within square brackets (for example, [2001:db8::1]).
BypassProxyHostList Must be set with a comma-separated list of FQDN or IP addresses that specify all Tanium Servers and the Module Server, 127.0.0.1, and localhost. You must enter IPv6 addresses within square brackets (for example, [2001:db8::1]). Specify literal values. Tanium Core Platform 7.0.314.6242 and later supports wildcards.

Note: Enhancements have been made in recent releases to automatically bypass the proxy server for these host addresses:

7.0.314.6573+ — Automatically bypass 127.0.0.1 and localhost.

7.1.314.3204+ — Automatically bypass 127.0.0.1 and localhost.

Tanium Core Platform 7.0.314.6242 or later supports wildcards. You must enter IPv6 addresses within square brackets (for example, [2001:db8::1]).

Tanium Zone Server

Settings Guidelines
AllowedHubs Enter a comma-separated list of IP addresses of Zone Server Hubs that are authorized to communicate with this Zone Server.
EnforceAllowedHubs Set the value to 1.
HubPriorityList This setting applies only to Tanium Core Platform 7.4 or later. The setting specifies the FQDN or IP address of the preferred Zone Server Hub for sending Tanium Client content (such as sensor definitions, configuration information, and action package files) to the Zone Server. As long as that hub is available, the Zone Server does not receive content from any other hub. If the preferred hub goes down, the Zone Server fails over to receiving content from any other available hub. Typically you use this setting for HA deployments that have pairs of Zone Servers and hubs, where each hub connects to each Zone Server. In HA deployments, adding the HubPriorityList is a best practice to ensure that each Zone Server receive content from its closest hub. Configuring this setting also optimizes hub usage by ensuring that each hub serves one Zone Server instead of one hub servicing both servers.
LogVerbosityLevel Log verbosity level:
  • 0: Logging disabled.
  • 1: Normal log level.
  • 41: Recommended during troubleshooting.
  • >= 91: Most detailed log level. Enable for short periods of time only.
ReportingTLSCertPath Setting for inbound connections. Path to the TLS certificate. This certificate is used in TLS connections that the Tanium Client initiated.
ReportingTLSKeyPath Setting for inbound connections. Path to the private key file used in TLS connections. This setting must be present to enable TLS.
ReportingTLSMode Configures TLS for outgoing connections that the server initiates. On a Zone Server Hub, you configure this option to enable TLS for the Zone Server Hub to Zone Server segment. Automatically set to 2 when you complete the Zone Server TLS setup.
  • 0 (TLS not used)
  • 1 (TLS required)
  • 2 (TLS optional)
RequireIncomingEncryption Setting for inbound connections. Automatically set to 0 when you complete the Zone Server TLS setup.
  • 0 (TLS not required)
  • 1 (TLS required)

Important: When RequireIncomingEncryption is set to 1, only TLS connection requests are processed, so only Tanium Clients that have TLS enabled are able to register and be managed. Do not set this to 1 until you are sure all Tanium Clients that have been deployed are configured to use TLS (ReportingTLSMode=1 or ReportingTLSMode=2), and you are ready to deploy Tanium Client to new endpoints with TLS configured prior to initial registration. Do not set this to 1 if your deployment has Tanium Client 6.0, which does not support TLS.
ServerName Tanium Server fully qualified domain name.
ServerPort Tanium Server Port. The default is 17472.
Version Tanium Zone Server version number.
ZoneHubFlag 0 if not the hub; 1 if the hub.

Settings specified during Installation are saved in the Windows Registry.

Tanium Server

Name Windows Registry Type Data
AddressMask REG_DWORD Hexadecimal value of a subnet CIDR that delineates the IPv4 clients that belong to a linear chain. Do not change this registry value unless your TAM instructs you to do so.
AddressPrefixIPv6 REG_DWORD IPv6 prefix represented as a decimal number between 0 and 128 inclusive that delineates the clients belonging to a linear chain. The default 0 specifies no peering. Consult your TAM to determine the optimum value for peering in IPv6 networks. Tanium Core Platform 7.3 and later.
AllowedHubs REG_SZ Enter a comma-separated list of Zone Server Hubs that are authorized to communicate with this Tanium Server. Specify the hubs by FQDN or IP address. You must enter IPv6 addresses within square brackets (for example, [2001:db8::1]). Note that you can configure the AllowLocalHubs key as an exception to the AllowedHubs list.
AllowLocalHubs REG_DWORD By default, this key is not present in the registry but has a value of 1, which enables any local Zone Server Hub to communicate with the Tanium Server regardless of the AllowedHubs setting. Add this registry key manually if you need it, but only with guidance from your TAM. Setting the value to 0 allows local Zone Server Hubs to communicate with the Tanium Server only if they are listed in AllowedHubs.
BypassCRLCheckHostList REG_SZ Servers that the Tanium Server trusts without checking a certificate revocation list (CRL). The Tanium Server performs a CRL check on all servers that are not in this list, and does not download files from a server that fails the check. Specify the servers by FQDN or IP address. You must enter IPv6 addresses within square brackets (for example, [2001:db8::1]).
BypassProxyHostList REG_SZ Hosts that bypass the proxy server. For example, do not use a proxy server for traffic between Tanium Servers in an active-active cluster.

A proxy server can cause problems with other traffic to a destination Tanium Server. For example, a package configuration can specify file URIs that are local to the Tanium Server to download content. It is important to bypass the proxy server for these URIs, or else the download will fail.

Enter the exceptions as FQDNs or IP addresses. You must enter IPv6 addresses within square brackets (such as [2001:db8::1]. In most cases, the exceptions you need to specify are localhost, 127.0.0.1 (IPv4), [::1] (IPv6), and all Tanium Server FQDNs and IP addresses. For example:

ts1.example.com, ts2.example.com,localhost,127.0.0.1, [::1],10.10.10.11,10.10.10.15

Specify literal values. Tanium Core Platform 7.0.314.6242 and later supports wildcards.

The Module Server host computer has a registry entry for the Tanium Server: 

HKEY_LOCAL_MACHINE\Software\Wow6432Node\Tanium\Tanium Server

The settings in this registry entry are for the proxy server configuration.

Name Type Data
BypassCRLCheckHostList REG_SZ Servers that the Tanium Server trusts without checking a certificate revocation list (CRL). The Tanium Server performs a CRL check on all servers that are not in this list, and does not download files from a server that fails the check. Specify the servers by FQDN or IP address. You must enter IPv6 addresses within square brackets (for example, [2001:db8::1]).
BypassProxyHostList REG_SZ Hosts that bypass the proxy server. For example, do not use a proxy server for traffic between Tanium Servers in an active-active cluster.

A proxy server can cause problems with other traffic to a destination Tanium Server. For example, a package configuration can specify file URIs that are local to the Tanium Server to download content. It is important to bypass the proxy server for these URIs, or else the download will fail.

Enter the exceptions as FQDNs or IP addresses. You must enter IPv6 addresses within square brackets (such as [2001:db8::1]. In most cases, the exceptions you need to specify are localhost, 127.0.0.1 (IPv4), [::1] (IPv6), and all Tanium Server FQDNs and IP addresses. For example:

ts1.example.com, ts2.example.com,localhost,127.0.0.1, [::1],10.10.10.11,10.10.10.15

Specify literal values. Tanium Core Platform 7.0.314.6242 and later supports wildcards.
ProxyPassword REG_SZ

For a basic proxy server that requires authentication, this setting is the account password used when establishing a connection with the proxy server. The password is stored in clear text within the registry.

This setting does not apply NTLM proxies, which use the credentials of the user context that runs the Tanium Server service.

ProxyPort REG_SZ Proxy server listening port.
ProxyType REG_SZ Basic or NTLM.
ProxyServer REG_SZ IP address of the proxy server. By default, the Tanium Downloader (TDownloader) service that manages downloads for the Tanium Server and Tanium Module Server resolves the ProxyServer address as an IPv4 address. If the proxy server has an IPv6 address, you must enter it within brackets (for example, [2001:db8::1]) and, on Windows systems, configure the Tanium Downloader registry with a ForceIPV6 key set to 1.
ProxyUserid REG_SZ For a basic proxy server that requires authentication, this setting is the account username used when establishing a connection with the proxy server. The password is stored in clear text within the registry.

This setting does not apply NTLM proxies, which use the credentials of the user context that runs the Tanium Server service.

TrustedHostList REG_SZ Enter a comma-separated list of FQDNs or IP addresses that specify all Tanium Servers and the Module Server. Traffic from 127.0.0.1 and localhost is trusted automatically. Tanium Core Platform 7.0.314.6242 or later supports wildcards. You must enter IPv6 addresses within square brackets (for example, [2001:db8::1]).

TDownloader

The Tanium Downloader (TDownloader) entry is used for log verbosity level and IPv6 support.

Name Type Data
LogVerbosityLevel REG_DWORD Specify one of the following decimal values for the log verbosity level:
  • 0: Logging disabled.
  • 1: Log level during normal operation.
  • 41: Best practice log level during troubleshooting.
  • 91 or higher: Enable the most detailed log levels for short periods of time only.
ForceIPV6 REG_DWORD Tanium Core Platform 7.3 and later. Add this registry key manually if you need it, but only with guidance from your TAM. In deployments where traffic between Tanium core platform servers and the Internet goes through a proxy server, TDownloader resolves the proxy address as an IPv4 address by default. If the proxy server has an IPv6 address, add the key and set its value to 1.

Zone Server

Name Type Data
AllowedHubs REG_SZ Enter a comma-separated list of Zone Server Hubs that are authorized to communicate with this Zone Server. Specify the hubs by FQDN or IP address. You must enter IPv6 addresses within square brackets (for example, [2001:db8::1]).
EnableFileCache REG_SZ This setting applies only to Tanium Core Platform 7.4 or later. If you installed the Zone Server Hub on a dedicated host instead of on the Tanium Server, set the value to 1 to enable the hub to cache package files for actions and files requested through the Tanium Client API. The hub provides these resources to the Zone Server without having to re-request them from the Tanium Server. To limit the cache size, set the hub_hot_cache_limit_in_MB.

In Tanium Core Platform 7.4 or later, the hub cache is disabled by default (value is 0) because the hub is typically installed on the Tanium Server, which has its own cache.
EnforceAllowedHubs REG_DWORD The default value 1 specifies that the Zone Server enforces the AllowedHubs setting: only Zone Server Hubs listed in AllowedHubs can communicate with the Zone Server. The value 0 enables any Zone Server Hub to communicate with the Zone Server regardless of the AllowedHubs setting.
hub_hot_cache_limit_in_MB   This setting applies only if the Zone Server Hub is installed on a dedicated host instead of on the Tanium Server. The hub uses its cache to forward Tanium Client content to the Zone Server without having to re-request the content from the Tanium Server. The content includes package files for actions and files requested through the Tanium Client API. Use the hub_hot_cache_limit_in_MB setting to limit the cache size. As a best practice, set the limit to whichever is the lesser value between 200GB and 60% of available disk space on the drive where the hub is installed.

In Tanium Core Platform 7.4 or later, the hub cache is disabled by default and therefore uses no disk space. If you enable the cache by setting the EnableFileCache value to 1, the default hub_hot_cache_limit_in_MB value is 0 (20% disk space). Do not enable the hub cache if the hub is installed on the Tanium Server, which uses its own cache.
HubPriorityList REG_SZ This setting applies only to Tanium Core Platform 7.4 or later. The setting specifies the FQDN or IP address of the preferred Zone Server Hub for sending Tanium Client content (such as sensor definitions, configuration information, and action package files) to the Zone Server. As long as that hub is available, the Zone Server does not receive content from any other hub. If the preferred hub goes down, the Zone Server fails over to receiving content from any other available hub. Typically you use this setting for HA deployments that have pairs of Zone Servers and hubs, where each hub connects to each Zone Server. In HA deployments, adding the HubPriorityList is a best practice to ensure that each Zone Server receive content from its closest hub. Configuring this setting also optimizes hub usage by ensuring that each hub serves one Zone Server instead of one hub servicing both servers.
LogPath REG_SZ Path to Tanium Zone Server logs.
LogVerbosityLevel REG_DWORD Specify one of the following decimal values for the log verbosity level:
  • 0: Logging disabled.
  • 1: Log level during normal operation.
  • 41: Best practice log level during troubleshooting.
  • 91 or higher: Enable the most detailed log levels for short periods of time only.
Path REG_SZ Installation path.
ServerName REG_SZ Tanium Server fully qualified domain name.
ServerPort REG_DWORD Tanium Server Port. Specified when you completed the installation wizard. The default is 17472.
ServiceUserDomain REG_SZ The Zone Server Windows service runs in the context of a service account. This entry contains the domain specified during installation.
ServiceUserName REG_SZ The Zone Server Windows service runs in the context of a service account. This entry contains the username specified during installation.
Version REG_SZ Tanium Zone Server version number.
ZoneHubFlag REG_DWORD The value indicates whether this Zone Server instance is (1) or is not (0) a Zone Server Hub.
zs_hot_cache_limit_in_MB   The Zone Server caches content that it provides to Tanium Clients without having to re-request the content from the Tanium Server. The content includes package files for actions and files requested through the Tanium Client API. Use the zs_hot_cache_limit_in_MB setting to limit the cache size. As a best practice, set the limit to whichever is the lesser value between 200GB and 60% of available disk space on the drive where the hub is installed.
