Application of Improved RBAC in System Login Component Design

Abstract

With the development of computer technology, the importance attached to the security of computer application systems is increasing day by day. Access control, as an important security technology, has been applied in the operating system, the database management system, security management and network operating system etc. This paper adopt the system ideology of high cohesion and low coupling in software engineering, achieve the design of login component by improving RBAC model under .NET platform, the model increases mechanism of direct authorize the users and shield part of users’ authority based on authorize main role, enriches the old RBAC mode of controlling authority, avoids the illegal operation of users, make sure the security of the system. Meanwhile, the component is well designed, and can be easily used as login component in large systems.
