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 project¶
Registry artifacts (such as security policy files) should be stored in a Registry Resource project. Follow the steps given below to create a project:
Open WSO2 Integration Studio and click Miscelleneous → Create New Registry Project in the Getting Started tab as shown below.
Enter a name for the project and click Next .
- Enter the Maven information about the project and click Finish .
- The new project will be listed in the project explorer.
Step 2: Creating a security policy as a registry resource¶
- Right-click the registry resource project in the left navigation panel, click New , and then click Registry Resource . This will open the New Registry Resource window.
- Select the From existing template option as shown below and
click Next .
Enter the following details:
Property Value Resource Name Sample_Policy Artifact Name Sample_Policy Template WS-Policy Registry gov Registry path ws-policy/
Click Finish and the policy file will be listed in the navigator.
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.
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 'org.wso2.micro.integrator.security.extensions.SecurityTokenStore'
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.
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.
Once you have select the data service file, click the browse icon for the Policy field.
Click workspace, to add the security policy from the current workspace. You can select the path to the
sample_policy.xml file that you created in the previous steps.
- Click OK, and the security policy will be added to the data
- Save the data service.
Step 3: Package the artifacts¶
See the instructions on packaging the artifacts into a composite application project.
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.
- Select the data service from the data service project, right click and go to -> Open With -> Text Editor . This will open the data service in text form.
Update the datasource configuration by adding the secret alias of the password. See the example given below.
<config id="Datasource"> <property name="org.wso2.ws.dataservice.user">root</property> <property name="org.wso2.ws.dataservice.password" svns:secretAlias="DB_Password_Alias"></property> <property name="org.wso2.ws.dataservice.protocol">jdbc:mysql://localhost:3306/Employees</property> <property name="org.wso2.ws.dataservice.driver">com.mysql.jdbc.Driver</property> <property name="org.wso2.ws.dataservice.minpoolsize"/> <property name="org.wso2.ws.dataservice.maxpoolsize"/> <property name="org.wso2.ws.dataservice.validation_query"/> </config>
Add the "http://org.wso2.securevault/configuration" namespace configuration to the datasource as follows:
4. Save the data service file.
<data enableBatchRequests="true" name="RDBMSDataService" serviceNamespace="http://ws.wso2.org/dataservice/samples/rdbms_sample" xmlns:svns="http://org.wso2.securevault/configuration">
