9 Overview You can deploy a Tanium Appliance in any of the following Appliance roles: Tanium Server The core server that communicates with clients. The Tanium Server also runs the UI console and API services and communicates with all other platform and solution components, as well as the content.tanium.com servers that host Tanium content packs and Tanium solution module import packages. The Tanium Server depends on a database server that is installed when the Tanium Server Role is installed. Tanium Module Server A dedicated server to run application services and store files for Tanium solution modules. It is installed on a separate appliance to prevent intentional or accidental scripts from having a direct impact on the Tanium Server. All-in-One Tanium Server, Tanium Module Server, and database server on the same appliance. An All-in-One deployment is supported only for proof-of-concept (POC) deployments. Tanium Zone Server A server typically deployed in an enterprise DMZ network to proxy traffic between Tanium Clients that reside on limited-access networks and a Tanium Server that resides on the trusted core network Tanium Inc. All Rights Reserved Page 9

10 Topology In an enterprise production deployment, the Tanium Server and Tanium Module Server reside on separate Tanium Appliances. Figure 1: Enterprise production or enterprise lab deployment 2017 Tanium Inc. All Rights Reserved Page 10

11 Prerequisites This topic summarizes prerequisites to Tanium Appliance installation. License A license is bound to the hostname(s) that you assign to the Tanium Server(s). For HA deployments, both hostnames are used in the license data. Let your technical account manager (TAM) know if the hostnames provisioned for the Tanium Server(s) are changed. SSL certificates The connections to the Tanium Console or SOAP and REST APIs, the connections between Tanium Server and Tanium Module Server, and connections to the Module Server are secured with SSL/TLS certificate and key exchanges. The installation process uses selfsigned certificates. We recommend that you verify the installation with the self-signed certificates before you replace them with your commercial or enterprise CA certificates. Doing this facilitates troubleshooting by separating potential installation issues and SSL issues. For more information on SSL certificate requirements, see the Tanium Core Platform Installation Guide. Network connectivity and firewall Tanium components use TCP/IP to communicate over IPv4 networks. IPv6 is not supported. You must work with your network administrator to ensure that the Tanium components are provisioned IP addresses and that DNS can be used to resolve hostnames. The following table summarizes the Tanium processes and default values for ports used in Tanium core platform communication. Network firewalls might need to be configured to allow the specified processes to send/receive TCP via the ports listed. For a detailed explanation, see the Tanium Core Platform Installation Guide. Table 1: Network communication ports used by Tanium components Components Processes Inbound Port Destination Port Tanium Server taniumserver 443, 8443, , 443, Tanium Module Server taniummoduleserver , 443, Tanium Inc.

13 modules. The Tanium Server may need to connect to additional locations, based on the components you import. The following table lists URLs that are accessed by Tanium Server. Import type Components URLs Any Any Content Initial Content Managed Applications Windows Security Patch Management IR Gatherer Modules IR Patch IOC Detect Labs Content EMET IR Memory MSERT Stinger Symantec Notes: If a Tanium content pack or solution module is not listed, it means no additional URLs are required for it. Previous Tanium Server versions required access to Tanium Server 7.0 and later do not require access to this site Tanium Inc. All Rights Reserved Page 13

14 If your enterprise security policy does not allow Tanium Server to access these locations directly, you can use proxy servers. See the Tanium Core Platform User Guide. If your enterprise network uses SSL intercept technologies, such as man-in-the-middle (MITM) proxies, you must configure them so that they do not prevent the Tanium Server and Tanium Module Server from downloading files from these locations. If you plan to deploy Tanium into an air-gapped environment, consult with your TAM Tanium Inc. All Rights Reserved Page 14

15 Getting started 1. Install the Tanium Appliance into a machine room and configure bootstrap network settings. For details, see the Tanium Appliance Quick Start Guide. 2. Connect to the TanOS console using SSH and configure basic network, host, and user settings. See Configuring network, host, and user settings on page Install the Tanium servers. See: Installing Tanium Server on page 32 Installing Tanium Module Server on page 36 Installing Tanium Zone Server on page Install the license file. See Installing the license file on page Verify the installation. See Verifying the deployment on page Tanium Inc. All Rights Reserved Page 15

16 Configuring network, host, and user settings You must configure basic network, host, and user settings before you can install a Tanium Appliance role. Configure temporary bootstrap network settings The Tanium Appliance Quick Start Guide describes how to install the appliance into a machine room and configure bootstrap network settings so that you can make a remote SSH connection and complete the setup and Appliance role installation from your desk. The Quick Start steps are repeated here to give context to the starting point for your initial workflows. Before you begin Connect a keyboard, video, and mouse (KVM) to the console port. Obtain an IPv4 address from your network administrator and be prepared to specify the IP address, subnet mask (dotted-decimal), and default gateway IP address. Configure the temporary settings 1. Power on the appliance. The boot and start-up processes take a few minutes. 2. When prompted to log in, specify the user name tanuser and the default password Tanium Tanium Inc. All Rights Reserved Page 16

17 3. When prompted, indicate that you want to configure temporary settings. 4. Specify the IPv4 address, subnet mask, and default gateway IP address. The TanOS console confirms that the settings are applied and logs you out. Configure network and host settings Network and host settings enable the appliance to establish connections with other computers in your local network and with other servers and hosts on the Internet. Specify appropriate settings for the network in which the appliance is deployed. Before you begin Your local "management computer" must be connected to a subnet that can reach the appliance IP address Tanium Inc. All Rights Reserved Page 17

18 Your management computer must have an SSH client application or terminal emulator that can make a client connection to the appliance. Be ready to specify the static IP address, subnet mask (dotted-decimal), default gateway IP address, hostname, domain name, primary and secondary DNS servers, NTP server(s), and time zone settings. You must have an SSH client such as PuTTY to log into the TanOS console. The latest version of PuTTY was used in testing. You must have an SSH key generator such as PuTTYgen to generate keys for the tancopy user. The latest version of PuTTYgen was used in testing. You must have an SFTP client such as WinSCP to copy files to and from the appliance. The latest version of WinSCP was used in testing. Configure the network and host settings 1. Make an SSH connection to the appliance IP address that was configured in the previous step. 2. When prompted to log in, specify the user name tanadmin and the default password Tanium1. 3. When prompted, indicate that you want to complete the initial configuration Tanium Inc. All Rights Reserved Page 18

19 4. Accept the end-user license agreement (EULA). 5. Specify network and host configuration settings. The console displays a notice that the passwords will be reset and the system restarted. You must configure a new password the next time you log in. Configure user access TanOS has a few built-in user accounts that you use to access the appliance operating system and perform tasks. Before you install a Tanium Appliance role, you must configure new passwords or add SSH keys to authenticate access for the following accounts: tanuser: Can make an SSH connection with password authentication to the TanOS console and access status menus Tanium Inc. All Rights Reserved Page 19

20 tanadmin: Can make an SSH connection with password authentication to the TanOS console and access all menus. tancopy: Can make an SFTP connection with SSH key authentication to TanOS and copy files to and from the /incoming and /outgoing directories. Before you begin Be ready to specify new passwords for the tanuser and tanadmin accounts. The password string must be at least 10 characters long and have at least 1 uppercase character, 1 lowercase character, 1 numeric character, and 1 nonalphanumeric character. You must have an SSH client to log into the TanOS console and an SFTP client to copy files to and from the appliance. You must have an SSH key generator to generate keys for the tancopy user. Change the default passwords 1. Log into the TanOS console as tanuser and then follow the prompts to change the password. 2. Log into the TanOS console as tanadmin and then follow the prompts to change the password. Add SSH keys for the tancopy account IMPORTANT: This procedure adds an authorized key for the tancopy user to the appliance configuration. The purpose of this key is to enable you to use an SFTP client on your management computer to copy files to the /incoming and from the /outgoing directories on the appliance. In the Tanium Module Server and HA active-active installations, you are instructed to add a different authorized key for the tancopy user. Be careful not to mistake one for the other. The authorized keys serve different purposes. Both are required Tanium Inc. All Rights Reserved Page 20

21 1. Use an SSH key generator such as PuTTYgen to generate a public/private key pair. 2. In PuTTYgen, select all of the text in the Public key for pasting into OpenSSH authorized_keys file box and copy it to the clipboard. IMPORTANT: In an SSH key exchange, the keys must match precisely as expected, including line endings. For this reason, the PuTTy documentation recommends loading the key in PuttyGen and copying it from the Public key for pasting... box instead of copying it from an open file Tanium Inc. All Rights Reserved Page 21

22 3. Log into the TanOS console as the user tanadmin. The TanOS console displays the tanadmin menu Tanium Inc. All Rights Reserved Page 22

Installing the license file on page Tanium Inc. All Rights Reserved Page 44

45 Installing Tanium Zone Server The Tanium Zone Server role installation creates the Tanium Zone Server and configuration file. The workflow described here also installs the Tanium Zone Server Hub Add-On and configures the Zone Server Hub to listen for connections from the Zone Server. Overview In Tanium deployments, Tanium Clients initiate communication with the Tanium Server. Your enterprise network security policies likely do not allow endpoints that reside in the untrusted network to initiate connections to resources that reside in the internal network, such as the Tanium Server. To enable the Tanium Server to manage these endpoints, you can deploy one or more Tanium Zone Servers in the DMZ to proxy communication from the external endpoints. The figure below illustrates Zone Server communication. The Zone Server is installed as a service, typically on an existing, shared device in the DMZ. It communicates with the Tanium Server through a Zone Server Hub process that you install as an add-on to the Tanium Server appliance. You set up external clients to register with the Zone Server as if it were the primary Tanium Server. To optimize performance as much as possible, the Zone Server is designed to cache sensor definitions, configuration information, and the files packaged in actions. It provides these resources to clients without having to re-request them from the Tanium Server. IMPORTANT: When using Tanium to manage external clients, be mindful that they might not have the same access to internal resources as internal clients. Target actions so that external clients are not instructed to attempt to access resources on the internal network, like an Active Directory server, or package files staged on an internal URL Tanium Inc. All Rights Reserved Page 45

46 Figure 3: Zone Server deployment Before you begin Make sure: Basic network, host, and user settings are configured. See Configuring network, host, and user settings on page 16. Network firewalls rules allow communication between the Zone Server hub and Zone Server on TCP port You have a copy of the Tanium Server public key file (tanium.pub) that you can upload to the Zone Server. See Download the Tanium Server public key file on page 127. Install the Tanium Zone Server This section provides procedures for the following workflow: 1. Deploy one or more Zone Server appliances in the DMZ. 2. Install the Zone Server hub add-on on the Tanium Server appliance and configure a Zone Server list that defines the Zone Servers with which it can communicate Tanium Inc. All Rights Reserved Page 46

71 Installing Tanium Server in an active-active cluster High-availability (HA) features support Tanium Server availability even when there is a failure or scheduled maintenance. The active-active cluster setup workflow installs the Tanium Server and a database server on each appliance, makes updates in the configuration files, and copies the license file, SSL certificates, and SSH public/private key pair from the first appliance to the second appliance. Overview HA clustering is not required to scale Tanium capacity or to improve performance. You can size the host system hardware and OS of standalone platform servers to meet your capacity and performance requirements. Rather, the Tanium Core Platform supports HA activeactive clustering of Tanium Server to ensure continuous availability in the event of an outage or scheduled maintenance. The following figure shows an HA topology. In an active-active deployment: Tanium Clients use a Tanium Server list to automatically find a backup server in the event the first Tanium Server assigned to them is unavailable. The Tanium Servers read and write to the database co-located on the first appliance. Data is periodically replicated from the first appliance database to the second appliance database. The local authentication user configuration is periodically synchronized between the two appliances. IPsec ensures end-to-end security between the two appliances. Each cluster member has a Tanium Console with its own URL. Tanium solution modules are installed on a shared Module Server. However, they must be imported in each Tanium Console in order to be accessed from each. The order in which you import solution modules into the Tanium Console determines the order in which they are displayed in the navigation menu. We recommend you import the modules in the same order on TaniumServer01 as you will on TaniumServer02 so that the menus are in the same order Tanium Inc. All Rights Reserved Page 71

72 Each server passes Tanium messages (for example, answers to questions) to the other cluster members. Package files that are uploaded to one member are synchronized to the other cluster members. HA is not supported for Tanium Module Server. You might want to provision a cold standby that you can bring into service to replace the Module Server in the event of hardware failure. Follow database administration best practices to ensure availability of the database server and that the Tanium databases and related database objects are backed up routinely. Figure 4: HA topology HA cluster requirements and limitations An HA deployment has the following requirements: Each Tanium Server must run the same software version, including build number (for example, each must have build number ). Each Tanium Server in the cluster must meet or exceed the requirements for the total number of endpoints targeted by your deployment. (Each must be able to independently handle load from the full deployment in the event of failure.) 2017 Tanium Inc. All Rights Reserved Page 72

73 The cluster members must be able to connect to each other via a reliable Ethernet connection. A minimum 1 Gbps connection is required. Each cluster member must be able to access the Internet to download files from designated domains. Access can be direct or made through a proxy server. Each cluster member must be able to connect to the shared Module Server. Before you begin Make sure: Basic network, host, and user settings are configured on both appliances. See Configuring network, host, and user settings on page 16. We recommend you allocate a network interface on each Tanium Server appliance for the HA cluster communication. Specify the IP addresses of the HA interfaces when you configure the IPsec tunnel. Specify the IP addresses of the Tanium traffic interfaces when you configure the HA cluster IP addresses. Your network security administrator has configured security rules to allow communication on the TCP ports that the Tanium core platform components use. In addition to the ports used by individual Tanium Servers, a Tanium Server in an HA cluster sends and receives HA-related data over an IPsec connection. The network security rules must allow ESP (50/ip) and IKE (500/udp, 4500/udp). Add required SSH keys An SSH key exchange is used to securely copy files from the first Tanium Server to the second Tanium Server during installation. 1.
