Description of the illustration dbfsg_vm

The image fmw_ras_session_service.png is similar to image fmw_app_stack.png and shows Real Application Security as it is implemented in the FMW stack as a Real Application Security servlet filter. The RAS filter sets up the session transparently, synchronizes the session with the OPSS subject, and consists of a set of Real Application Security APIs that function in the session as session APIs, a privilege elevation API, namespace APIs, and a check privilege API. This implementation is further described in the text that follows the illustration.
