Design and implementation of an intrusion-tolerant application server middleware-based

In consideration of the fact that the existing implementation of intrusion tolerance mechanisms is in the application layer, with the problem that it does not divide the business logic from the intrusion tolerance function, the paper proposes an intrusion-tolerance middleware model based on the interceptor on the basis of analyzing intrusion the tolerance requirements and the architecture of the J2EE application server, which logically divides the intrusion-tolerance functions into service providers and service management. A system was designed by using the intrusion tolerance security model and the element technology, the theory of intrusion tolerance mechanism and the strategy of implementation were described, and the intrusion tolerance technology and the implementation method were extracted. Finally, an intrusion-tolerance J2EE middleware was realized and built on the JBoss, an open source J2EE Application Server Platform, with the dynamic load of the intrusion-tolerance class being implemented through Java class load mechanism.
