Abstract:
1. A security component within a supervisory process control and manufacturing information system comprising: one or more memory devices storing software for performing functions of the security component; a processor connected to the one or more memory devices, said processor executing the software for performing functions of the security component; a set of user roles, stored on the one or more memory devices, corresponding to different types of users within the system; a set of security groups, stored on the one or more memory devices, defining a set of security permissions with regard to a set of objects, said objects including a set of primitives and a set of attributes, wherein the primitives contain business logic that, when executed, facilitate carrying out a process control function and wherein the attributes are unique to the function of the primitives, wherein each security group includes an access definition relating the security permissions to at least one of the set of user roles; and a set of user accounts, stored on the one or more memory devices, assigned to at least one of the defined roles thereby indirectly defining access rights with regard to the set of objects having restricted access within the system; wherein the security permissions are assigned at an object attribute level to permit writing to the attributes based on the defined access rights; and wherein the system has a layered architecture, said layered architecture comprising application objects that model entities within a process control system, engine objects that host execution of the applications in a runtime environment, and platform objects corresponding to a physical computer system component for executing the engine objects and associated application objects and wherein the platform objects host at least one of the engine objects.
