As the fast development of the global informationization, it is changingthe way people living as well as promoting the growth of the economics, whichfurther accelerates the integration of the worldwide economics. The degree ofinformationization represents the level of development of the countries.Meanwhile, information management systems have been applied in variousaspects within the society, especially for the enterprises with huge amount ofinformation. However, the expanding work content leads to the increase of theinformation, which makes it more difficult to maintain the systems. Also, theinternet, as main media of data transportation, contains lots of insecurityissues.Hence, constructing a strong management system is quite important forthe operation of the whole enterprise.Access control is one technology that ties to validate the users who wantto have access to the systems so that it can protect the resources fromdamaging.It is quite important to make sure that the key resources can not beeasily accessed.Also, when some others tend to have an illegal access, they willbe denied. Therefore, it could be very meaningful to build a strong and commonaccess control model in order to make the system safe. Role-Based Access Control（RBAC), as one of the most effective models, has been largely used within manyenterprises. While minimizing the complexity and reducing the cost, it cansupport the security strategy of enterprises neatly.RBAC provides great flexibility to handle the security problem.Based on theintroduction to the underlying principles of the RBAC model, the paper inducesthe implementation of permission management system for the marketing servicesystem in GRID Corporation.
