When the REST gateway is enabled, anyone with access to the servlet can access data in a data grid. Therefore, you must use web application security in WebSphere Application Server to control authorization. For more information about securing your web applications that use this REST gateway, see Securing web applications in the WebSphere Application Server Information Center.
You can now begin using the REST data service in the Liberty profile to communicate with the data grid through a URI. For more information, see Developing data grid applications with the REST gateway.
