Applying Security to a Data Service

WSO2 supports WS-Security, WS-Policy, and WS-Security Policy specifications. These specifications define a behavioral model for Web services. To enable a security policy for a data service, you need to first create a security policy file, and then add it to the data service.


Be sure to configure a user store for the Micro Integrator and add the required users and roles.

Step 1: Creating a registry resource module

Registry artifacts (such as security policy files) should be stored in a Registry Resource module. Follow the steps given below to create a module:

  1. Right click on the Integration project and goto New → Registry Resource.

    !!! Tip Alternatively, you can goto File → New → Others and select Registry Resources from the opening wizard.

  2. Enter a name for the module and click Next .

  3. Enter the Maven information about the module and click Finish .
  4. The new module will be listed in the project explorer.

Step 2: Creating a security policy as a registry resource

  1. Right-click the registry resource module in the left navigation panel, click New, and then click Registry Resource. This will open the New Registry Resource window.
  2. Select the From existing template option as shown below and click Next .
  3. Enter the following details:

    Property Value
    Resource Name Sample_Policy
    Artifact Name Sample_Policy
    Template WS-Policy
    Registry gov
    Registry path ws-policy/
  4. Click Finish and the policy file will be listed in the navigator.

    1. Let's use the Design View to enable the required security scenario. For example, enable the Sign and Encyrpt security scenario.


      Click the icon next to the scenario to get details of the scenario.

    2. You can also provide encryption properties, signature properties, and advanced rampart configurations.


      Using role-based permissions?

      For certain scenarios, you can specify user roles. After you select the scenario, scroll to the right to see the User Roles button. Either define the user roles inline or retrieve the user roles from the server.


      Switch to source view of the policy file and make sure the tokenStoreClass in the policy file is ''

  5. Save the policy file.

Step 2: Adding the security policy to the data service

Once you have configured the policy file, you can add the security policy to the data service as explained below.

  1. If you have already created a data service using WSO2 Integration Studio, select the file from the Project Explorer.


    Be sure to update your database credentials in the dataservice file.

  2. Once you have opened the data service file, switch to the Source View to see the source of the data service.

  3. Add the following elements inside the <data> element and save the file.

     <policy key="gov:ws-policy/Sample_Policy.xml" />
     <enableSec />

Step 3: Package the artifacts

See the instructions on packaging the artifacts into a composite exporter.

Step 4: Build and run the artifacts

See the instructions deploying the artifacts.

Step 5: Testing the service

Create a Soap UI project with the relevant security settings and then send the request to the hosted service.

Using an encrypted datasource password

When you create a data service for an RDBMS datasource, you have the option of encrypting the datasource connection password. This ensures that the password is encrypted in the configuration file (.dbs file) of the data service.

See the instructions on encrypting plain-text passwords

Once you have encrypted the datasource password, you can update the data service as explained below.

  1. Open the data service and click Data Sources to expand the section.
  2. Click on the Edit icon of the respective Datasource to open Edit Datasource page.
  3. Make sure to check Use as a Secret Alias.
  4. Update the Secret Alias and click on Save.
