Design And Implementation Of Policy Management System Based On The Label

With the development of Computer Technology and the extension of network application,the Internet has brought lots of convenience,at the same time the security needs are constantly changing.People tend to use electronic tools in the process of information processing,so in order to prevent threats from within and outside the system,it not only requires the integrity of the information but also requires the safety of the information.These changes increase the difficulty of the protection of the data and service,some access control technologies are difficult to describe and manage with the traditional methods such as MAC and DAC.So it is necessary to study more perfect access control method and develop more sophisticated policies to manage the service and source that the users want to visit,and at the same time,there is a necessary strengthen the management of security policy to realize real-time matching strategy which can guarantees the above process.In order to solve the mentioned problems,this paper proposes a label-based policy management system solution to provide an improved policy technology and a more fine-grained access control technology.The main research work of this paper includes:first,research the current related access control management model then design a method which can achieve the classification and verification of the label;secondly,propose a label-based policy management system solution;third,implement the policy management system and build a test environment to carry out a detailed test.After a detailed function verification and performance test,the result show that the solution which proposed by this paper can update the access control policy in real-time and manage the access behavior of the system users.Besides,the users' increase did not have a significant impact on the system performance.
