The Security Manager is a Studio feature that filters the data that users can see in Studio. If you want to provide extra security for Studio, you can use the Component SDK to create a custom Security Manager to restrict access to specific data.
The Component SDK package contains a sample Security Manager that you can use as a starting point. You can configure the Security Manager to filter your data at the record level based on user, group, and role. Once your Security Manager is complete, you can deploy it and configure Studio to use it.
For more information on the Security Manager, see the Studio User's Guide and the Extensions Guide.
