The Internet has become an essential part of normal operations of both public and private sectors. Many security issues are not addressed in the original Internet design, and security now has become a large concern for networking research and study. There is an imperative need to have an simulation environment that can be used to help study security-related research problems. In the thesis we present our effort to build such an environment: Real-time Immersive Network Simulation Environment (RINSE). RINSE features flexible configuration of models using various networking protocols and real-time user interaction. We also present the Estimate Next Infection (ENI) model we developed for Internet scanning worms using RINSE, and the effort of combining multiple resolutions in worm modeling
