Improved RBAC Model Research And Its Application In The Office System

With the science technology development and popularization of computers,enterprises and institutions of the computer information management requirements arealso increasing. And in their office management system,access to mechanisms occupya crucial role. Because good access control model capable of landing system is veryeffective user management, legitimate users can query the system information anddata, but to ensure that unauthorized users disable access. This can be very effectivein preventing unauthorized access to the system illegal users. In the current businessmanagement systems more common access control models have a lot, but in thecurrent number of access control is the most widely used role-based access control(RBAC). RBAC model combines the advantages of both DAC and MAC models byintroducing roles (Role) the concept of making a variety of operating authority for thesystem is not granted directly to the user, but to grant roles. Therefore, to achieve alogical separation of users and permissions, simplifying the user’s authorizationmanagement, greatly reducing system overhead. As the RBAC model can well reflectthe organizational structure of the system unit and personnel division of relationshipwith each other, so this model has been widely studied and applied.This essay RBAC were more extensive and detailed study, we propose amodified RBAC model (S-RBAC). In addition to this model inherits all theadvantages of RBAC, the unit office in the practical application of the system moreflexible and practical. This paper proposes a new model for RBAC implementationmechanism-by adding a set of permissions and access control scheme operatingfunction set, this new model is proposed in this paper can not only solve someshortcomings of the original model, it also reduces the role due to add another belt tothe appropriate authority complexity, because the operating functions of the rolewhich has a collection of set-up time and the number of operations functions, makingthe newly added character can be deleted automatically after the completion of thetask in the workflow, thus improving the efficiency of the administrator, reducingthe burden. Because the operating function set can add,so you can control moreconvenient for the role.In this paper, the design and implementation of an improved RBAC model officesystems.The system combines the S-RBAC permissions model has been specificallydesigned to block part of the description, including the role of management, department management, user management, privilege management, processtemporary roles management, rights management and other parts of the set. Aftertesting and commissioning, the system is running well.
