Confirming the Tachyon website HTTPS binding
If you have implemented Tachyon Server on an IIS server that has previously been or is currently used by other applications then there may be other Web Server certificates in the Local Computer's Personal Certificates store in addition to the Tachyon Web Server certificate. In earlier versions of Tachyon it was possible under these circumstances for the Tachyon Server installer to bind to the wrong certificate. The current version contains improved logic for avoiding this problem, but it is still good practice to verify that the configuration is indeed as expected.
To select the correct certificate for the HTTPS binding see the troubleshooting steps for Server installation issues.
Immediately after installation you can only access the Tachyon Portal and the Settings application using the installation account, until additional users have been added and assigned to their roles.
The installation account is assigned the following roles and cannot be modified because it is a System Principal.
- Permissions Administrators
- Instruction Set Administrators
- Consumer Administrators
- Applications Administrators
This means that one of your first steps after installation is to connect to the Portal using the installation account and add other Tachyon users with necessary roles as described in the Users page and the Roles page.
After the initial configuration of Tachyon users and groups has been performed we recommend that the above roles are applied to one or more other Tachyon users and that the installation account is disabled in Active Directory. It can be enabled later for installation of updates and upgrades.
This approach of having a dedicated installation account ensures the same account is used for all installation activities and has relevant rights on the Tachyon server and in SQL Server. Disabling it makes it more secure than a normal user account. If an ordinary user account is used for installation tasks there is a risk the account may be deleted, causing difficulties for future upgrades or re-installations.
Add Product Packs and configure Instruction Sets
Tachyon functionality is based around Instructions, until these are added to the system you will not be able to ask questions or perform actions. 1E provides instructions in zip files called Product Packs. A collection of Product Packs necessary for for zip files available in the Tachyon Platform zip (available on the 1E Support Portal) and from the Tachyon Exchange (tachyonexchange.1e.com). Each Product Pack contains a related collection of Instruction Definitions. Product Packs and Instruction Definitions can be added to Tachyon by Instruction Set Administrators.
When added into Tachyon, Instructions are immediately allocated to the built-in Unassigned Instruction set. Instruction sets provide a way of determining the permissions for the Instructions they contain, but the Unsassigned Instruction set is only intended as a staging area for newly loaded Instructions - and Instructions in this set cannot be used directly. An Instruction can only belong to a single Instruction set, so after loading it into Tachyon, and before it can be used, it must be moved to another Instruction set - one created by an Instruction Set Administrator.
Instruction sets created by Instruction Set Administrators can be used as the basis for custom roles created by Permissions Administrators. These custom roles determine the permissions for the Instruction sets and all the Instructions they contain. This enables the Permissions Administrators to complete the assignment of specific Instruction set roles to users and determine which Instructions they can action, approve, question or view.
You can either load instructions into Tachyon and create Instruction Sets for them automatically from Tachyon Setup, please refer to Quick Start: Uploading Product Packs using the Tachyon Product Pack deployment tool for more details, or you can load the product packs and create their associated instruction sets by hand.
The ProductPacks folder in the Tachyon Platform zip file contains a number of Classic and Integrated product pack zip files:
- 1E ConfigMgrConsoleExtensions Product Pack — Classic Product Pack used to create the 1E ConfigMgrConsoleExtensions instruction set required by the Tachyon Configuration Manager console extensions.
- 1E Explorer TachyonAgent Product Pack — Classic Product Pack used to create the 1E Explorer TachyonAgent instruction set that can be used to configure and query Tachyon clients.
- 1E Explorer TachyonCore Product Pack — Classic Product Pack used to create the 1E Explorer TachyonCore instruction set that includes instructions for Tagging and Quarantine.
- 1E Inventory Product Pack — Classic Product Pack used to create the 1E Inventory instruction set required by the Tachyon Powered Inventory feature.
- 1E Patch Success Product Pack — Classic Product Pack used to create the 1E Patch Success instruction set required by the Patch Success application.
- 1E Tachyon Platform Product Pack — Classic Product Pack used to create the 1E Tachyon Platform instruction set required by the Tachyon Platform verification process.
- Microsoft SCCM Client Health Integrated Product Pack — Integrated Product Pack used to create the MS SCCM Client Health instruction set and Microsoft SCCM Client Health policy.
- Nomad Client Health Integrated Product Pack — Integrated Product Pack used to create the Nomad Client Health instruction set and Nomad Client Health policy.
- Windows Client Health Integrated Product Pack — Integrated Product Pack used to create the Windows Client Health instruction set and Windows Client Health policy.
- Tachyon Core Integrated Product Pack — Reference for the policy objects contained in the Integrated Product Pack: Tachyon Core.
- Trigger templates and preconditions reference — Reference for all the precondition fragments and trigger templates available in Integrated Product Packs included in the Tachyon Platform zip. These can be used to create your own custom rules and policies.
Deploy Tachyon clients
You will need to deploy the Tachyon client to at least one device in order to use any instructions.
Please refer to Deploying Tachyon clients for guidance on deploying clients to Windows and non-Windows devices.
Configure the Tachyon Server to support the Export all responses feature
The Export all feature is displayed on the responses page for a question once it has finished retrieving all its responses. To enable this to work you need to configure the following:
- Configure BCP:
The Export all feature is described in Exporting data from Tachyon Explorer. To enable Tachyon users with the appropriate permissions to use the Export all feature you must ensure that Microsoft Bulk Copy Program (BCP) is installed on each Tachyon Response Stack server, specifically where the Core component is hosted.
- If Microsoft SQL Server is installed on the same server as the Tachyon Response Stack then BCP will normally be present.
- If the TachyonResponses database is remote to the Tachyon Response Stack and there is no local copy of Microsoft SQL Server then you will need to install BCP.
You can confirm BCP is installed by starting a command prompt and typing bcp and usage information is displayed. The command bcp -v displays the version.The information here applies regardless of which version of SQL Server is being used. This does not imply that Tachyon itself is supported under every possible version of SQL Server that falls within those ranges. See Requirements for the supported versions and required Service Packs.
Install the following components to get BCP working:
Installer file name Product Name Where to get it from vc_redist.x64.exe Visual C++ 2017 Redistributable https://support.microsoft.com/en-gb/help/2977003/the-latest-supported-visual-c-downloads msodbcsql.msi Microsoft® ODBC Driver 13.1 for SQL Server®
This needs to be installed because of a known issue in the Microsoft Command Line Utilities 15 for SQL Server.
msodbcsql.msi Microsoft® ODBC Driver 17 for SQL Server® https://www.microsoft.com/en-us/download/details.aspx?id=56567
Microsoft Command Line Utilities 15 for SQL Server https://docs.microsoft.com/en-us/sql/tools/bcp-utility
To verify the components have been installed you can use AppWiz.cpl and check for the Product Name.
Configure the share:
The Export all feature enables the bulk copying of the entire completed responses for a Tachyon question to a specified network share.
As this may potentially be a very large data set the location must have sufficient disk-space to store the exported data.
To use this feature you must create one or more network shares on the Tachyon Server or other location, and configure NTFS and share permissions as follows. If desired, it can be hidden using a $ at the end of the share name.
Configure the share with Everyone modify access, or the same as the NTFS security.
The share folder needs modify access configured for the service account(s) used by the Tachyon Core application pool on each Response Stack server and the service account used by the Tachyon Consumer application pool on the Master Stack server. By default this account is NT AUTHORITY\NETWORK SERVICE (if the share folder is located on a Tachyon 'all-in-one' server where both the Tachyon Consumer and Core components are installed e.g. Master Stack and Response stack). However, there is another scenario where the share folder is neither located on the same server as the Tachyon Consumer or Tachyon Core components, but on a remote fileserver (like a NAS device, DFS share, etc). In this case, the Tachyon Consumer AND Tachyon Core components will attempt to connect to the share folder as their respective computer accounts, for example <domain>\<computer$>.
Therefore, depending on where the share folder is located, you will need to configuring NTFS permissions for the following:
- If the share is on the same server as the Tachyon Core application pool, the share must have NTFS Modify permissions added for the built-in NT AUTHORITY\NETWORK SERVICE account local to the server.
- If the share is remote from the server used by a Tachyon Core application pool, the share must have NTFS Modify permissions added for the server$ account. For example, if the Tachyon Core application pool is running on a server called ACME-TCN01 the server account ACME-TCN01$ would need to be added to the remote share with NTFS Modify permissions.
If you have installed multiple Response Stacks, then repeat the preceding step, adding permissions on the share for each of the computers that are running a Tachyon Core. For instance, if you have deployed Response Stacks on two computers called ACME-TCN01 and ACME-TCN02, then the server accounts ACME-TCN01$ and ACME-TCN02$ would need to be added to the share with NTFS Modify permissions.
Alternatively, you can use an AD security group that contains the computer$ account of all your Tachyon Servers.
Include any user accounts or AD groups that would require access to the share.
The preceding are the minimum permissions required. Of course, if your share has more permissions it will also work for Export All. For example, if your share inherits from its parent the Modify permission for Authenticated Users, then this will automatically include permission for local and remote computer$ accounts, so you will not need to explicitly grant the permissions mentioned above.
|Error: Header-row missing in .tsv file export||Tachyon Consumer has no access to share folder|
|Error: Contents missing in .tsv file export||Tachyon Core(s) has no access to share folder|
|Successful: Both header-row and contents correctly included in .tsv file export||Tachyon Consumer and Tachyon Core(s) have access to share folder|
The following tasks are not essential but may enhance the performance and use of Tachyon in your environment.
Add an inventory connector
You can add an inventory connector to Tachyon that will sync data from a data source to an inventory repository. Typically this connector would be to another system such as Configuration Manager or to Tachyon itself. For more details please refer to the Connectors page. At least one configured inventory connector is required to support management groups.
Create management groups
You can create Management groups to partition your estate into groups of devices that can be managed separately. This is done by creating a management group in the Settings application, please refer to Management groups page and Management groups - tutorial for more details. To synchronize the management groups with Explorer you'll need to add a Tachyon connector, please refer to Tachyon connector for more details.
Change Tachyon database owner to 'sa'
After the databases have been created, best practice is to change the owner of each database to sa, to avoid issues if the owner's Windows account is deleted in future.
The following script can be used to change the owner of each Tachyon database to sa. This will work even if the sa login has been disabled, which is also best practice.
Ensure the Server Installation Account retains the db_owner role on the database to support re-configuration and upgrades. If the account is removed from being owner, then it will also be removed from the db_owner role and will need to be re-assigned, for example by using the Grant db_owner SQL script.
The owner user and db_owner role are both mapped to the database dbo user. It is preferable for the account to be a member of the db_owner role, instead of being the owner user.
Lock down the Switch SSL Certificate folder
If you want additional protection for the Switch's certificate then you can change the NTFS security on the Switch's SSL folder as described in Services and NTFS Security.
You should also remove the original copies of the certificate files from the installation files.
Changing the SMTP Host configuration
The Tachyon Server installer does not support configuration of SMTP credentials, but these can be configured post-installation. By default, Tachyon assumes port 25 and anonymous authentication.
Tachyon stores its SMTP configuration in
- <INSTALLDIR>\Tachyon\Coordinator\Tachyon.Server.Coordinator.exe.config (workflow emails)
After any changes reboot the server or restart the 1E Tachyon Coordinator service.
Microsoft's documentation for the SMTP network section can be found here: https://msdn.microsoft.com/en-us/library/ms164242(v=vs.110).aspx.
When defaultCredentials is set to true, the mail subsystem uses the Windows credentials from the process under which the coordinator service is running to connect to the mail server. In general, this will only work with Microsoft servers, or servers that allow anonymous connections. To use different credentials, set defaultCredentials="false" and add values for username and password (and, optionally, clientDomain ).
To use an encrypted connection, if the server supports it, add enableSsl="true". Change the port as needed, for example, port="465" or port="587".
Microsoft supports parameters named host and From, but these are ignored by Tachyon because the smtpHost and TachyonEmail keys in the <appSettings> section take precedence.
If smtpHost is set to empty (blank) in a config file then email is disabled for the corresponding feature.
The Two-factor Authentication feature requires email. Therefore if smtpHost is set to empty, then the 2FA feature must be disabled by setting <add key="2FAEnabled" value="false" /> in the <INSTALLDIR>\Tachyon\Coordinator\Tachyon.Server.Coordinator.exe.config file.
Finally, reboot the server or restart the 1E Tachyon Coordinator service.
Enabling or disabling Two-factor Authentication
2FA is optionally disabled (enabled by default) in Tachyon Setup: Active Directory and email screen. If you need to change this after installation, then you need to edit the setting <add key="2FAEnabled" value="true" /> in the <INSTALLDIR>\Tachyon\Coordinator\Tachyon.Server.Coordinator.exe.config file.
If enabling 2FA, please refer to Requirements: Two-factor Authentication Requirements and Requirements: Email Requirements.
