A Multi-level Security Local Area Network System based on BLP

With the development of computer network,there come a lot of security threats.LAN is a basic unit of network functionality,and its security is very important and significant.A Multi-level Security Local Area Network System(MSLANS) based on BLP model is proposed,which with transparent computing system as the platform,conforms with the requirements of security infrastructure.By introducing the security policy server and dynamic monitoring switch into the system,and embedding modules into terminal computers to monitor the user's operations and login procedures,the secure LAN system could thus accomplish the centralized control and protection of the operations within the terminal computers.
