Security and authorization guide

This tutorial describes how to configure the data access security in Flexmonster Data Server used as a Windows/Unix service. To connect the Data Server to your data, refer to the Data sources guide. To install the Data Server as a service, see the Getting started with the Data Server guide.

Flexmonster Data Server supports different essential security configurations, such as built-in basic authorization and HTTPS. To learn more about security configurations in the Data Server, see the following guides:

Built-in basic authorization

By default, Flexmonster Data Server is accessible to anyone who can reach its host. Using the built-in basic authorization, you can restrict access to Flexmonster Data Server.

Step 1. Create a user

Open Flexmonster Admin Panel and go to Security > Add New User. Define a username and password, then select Create to add the user.

Once a user is created, you cannot change the username.

Learn more about managing the users in our guide on the Admin Panel.

Step 2. Enable authorization

Go to the Settings tab. Turn on the basic authorization using the Basic auth toggle switch:

Step 3. Configure CORS

Basic Authorization requires certain origins to be defined in the Access-Control-Allow-Origin header. Origin is a domain that sends requests to Flexmonster Data Server (e.g., http://localhost:8080 or

To specify origins that can send requests to the Data Server, fill in the Allow origin input field on the Settings tab.

To specify several origins, separate them with a comma:

Step 4. Configure credentials on the client side

In this step, credentials are configured in Flexmonster Pivot. There are two ways to configure credentials:

  1. Use the withCredentials property:
    dataSource: {
        type: "api",
        url: "http://localhost:9500",
        index: "data",
    withCredentials: true
    In this case, you need to enter your login and password when first connecting to Flexmonster Data Server.
  2. Add a request header with basic authentication. The header should be added in the following way:
    dataSource: {
        type: "api",
        url: "http://localhost:9500",
        index: "data",
    requestHeaders: {
    "Authorization": "Basic QWxhZGRpbjpPcGVuU2VzYW1l"

    The header should be specified in the standard for basic authentication format.
    In this case, the authorization will be automatic, and the browser will not ask for the login and password.

Configure the HTTPS protocol

All data sent by HTTP is not encrypted and can be inspected. To make the Data Server more secure, we added an option to enable the HTTPS protocol. Follow the steps below to configure a secure HTTPS connection.

Step 1. Enable the HTTPS protocol

Open Flexmonster Admin Panel and go to the Settings tab. Turn on HTTPS using the HTTPS toggle switch:

Step 2. (optional) Add a certificate

If needed, you can also add an SSL/TLS certificate. There are two ways to add a certificate:

  • By specifying its path and password.
  • By specifying its subject and store.

Path and password

To add a certificate using its path and password, follow these steps:

  1. On the Settings tab, set the Certificate type configuration to Path-Password.
  2. Specify the path to the certificate and the password required to access it. You can click on the folder icon to choose the needed certificate using Explorer.

Adding the certificate is possible only when HTTPS is enabled.

Your configuration should look similar to the following:

Subject and store

To add a certificate using its subject and store, follow these steps:

  1. On the Settings tab, set the Certificate type configuration to Subject-Store.
  2. Specify the certificate subject name and the certificate store from which to load the certificate.
  3. (optional) By default, the location of the certificate store is Current User. If the needed location is Local Machine, select this option in the Location configuration.
  4. (optional) To allow using invalid certificates, such as self-signed certificates, enable the Allow invalid toggle button.

Adding the certificate is possible only when HTTPS is enabled.

Your configuration should look similar to the following:

Step 3. (optional) Configure the protocols

The Protocols configuration establishes the HTTP protocols enabled on a connection endpoint or for the server. The Protocols configuration can have one of the following values: HTTP1, HTTP2, and HTTP1 and HTTP2. For example:

Reverse proxy authorization

If you need to use your own authorization mechanism, you can restrict the public access to Flexmonster Data Server and enable access to it through the reverse proxy. This approach requires implementing the proxy, which is responsible for the data access control. The proxy will decide which requests should be accepted and passed to the Data Server, and which requests should be declined.

The proxy has to implement the custom data source API to handle requests from Flexmonster Pivot. Then the proxy will be able to redirect Flexmonster Pivot’s requests to the Data Server. To see the full list of requests sent by Flexmonster Pivot, refer to our documentation.

Custom authorization and role-based permissions

Role-based access is supported when using Flexmonster Data Server as a DLL. Flexmonster.DataServer.Core.dll allows performing server-side filtering, so it becomes possible to show different subsets of the data to different user groups.

To demonstrate the usage of server-side filtering for role-based permissions, we created an ASP.NET application with a custom server using Flexmonster.DataServer.Core.dll.  The GitHub repository contains a solution file DemoDataServerCore.sln, so the sample can be opened and launched via Visual Studio.

To start the sample application from the console, run the following commands:

cd DemoDataServerCore
dotnet restore
dotnet run

To see the result, open http://localhost:5000/ in the browser.

On the page, there is the pivot table and the drop-down menu. Select a role from the menu to see how it affects the data shown in Flexmonster.

To see how the server-side filtering is implemented in the sample server, refer to the FlexmonsterAPIController.cs file.

To learn more about the server filter, see the Implementing the server filter guide.

Secure configuration setting

To store connection strings and other configurations more securely, you can set them dynamically as command-line arguments or environment variables. This approach requires using the Data Server as a console application. For details on passing dynamic configurations to the Data Server, see the documentation.
