Abstract�� A main problem of recent researches on network security simulation is the lack of methods to model attack and uniform description. Hence computer network attack description language(CNADL) was presented, with attack tree adopted to model attacks and describe purpose, characteristic and process of attack. Attack tree was used to model attacks and then transformed to automata model. CNADL, which was attack tree model oriented and designed in context-free grammar, described the goal, means and process of different attacks in uniform format. The interpreter translated CNADL into corresponding orders and sent them to attack drilling system. Based on GTNetS simulator, the attack drilling system tested the validity of CNADL. The experimental results show that CNADL is able to describe attack characteristics efficiently, and simulate denial of service(DoS), worm password attack and IP spoof based on GTNetS.
