Agent-based modeling and simulation of network softbots' competition

The research devoted to design and implementation of new knowledge-based methods and tools for verification and validation of complex software systems is now an important direction of scientific investigations. The paper describes the approach and software environment developed for agent-based modeling and simulation of defense against coordinated distributed attacks in the Internet. According to this approach, the cybernetic opposition of malefactors and defense systems in the Internet is represented by competition of antagonistic softbots' teams. The possibility of the approach application is analyzed by testing the defense mechanisms against Distribute Denial of Service attacks.
