摘要：To solve worm propagate in the network system, the research situations of Internet worm prevention technology by system vulnerability are first discussed; then the concept and the execution mechanism of containment system are given; the Centralized Containment Model based on the active containment scenarios and the worm propagation model under these scenarios are presented afterwards; and finally the research trends in this area are also addressed.
