Abstract

How to evaluate the effectiveness of the network attack, network attack and defense research is of great significance. Currently, due to the sensitivity of the attack, the domestic and international public research in this regard is not more study of the theories and methods of performance evaluation of network attacks, helps make up our network attack and defense as well as network security infrastructure inadequate. Given the qualitative and quantitative evaluation of the performance of the network attack, on the one hand to help the attack square test the effectiveness of aggressive behavior, prompted constantly develop new attack techniques and means; the other hand, also contribute to the defense side to take a more effective network security strategies and methods to promote the upgrading of its safety performance. Effectiveness Evaluation of three important aspects involved in the performance assessment process in this article around the network attack, network attacks, network attack modeling and network attack effectiveness evaluation study. The main contribution of this work and innovation are summarized as follows: (1) from the point of view of the process of the implementation of the cyber attacks to establish a new set of attack effectiveness evaluation index system. The attack classification in accordance with the process of implementation of the cyber attacks on each type of attack analysis and refinement, effectiveness evaluation index system for a network of 84 indicators attacks. Phased assessment of the index system to meet demand, and to be detectable, operability, and reduce the interference of human factors, to increase the objectivity of the performance evaluation results. (2) proposed an expansion of attack description language Enhanced LAMBDA. The language on the the LAMBDA language of foundation, the expansion of the description of the time constraints and performance constraints, the experimental results show that the Enhanced LAMBDA language can accurately describe the complex combination of attack, and can effectively support the performance evaluation of the combo attack. (3) An improved network the attack performance assessment method based on rough set theory. In terms of discrete data, proposed an improved integration discretization algorithm based on the breakpoints importance, utilize rough set particularity, to ensure the quality and efficiency of discretization. In weight to determine aspects, organic integration using a subjective and objective weighting method calculated from the difference between the square and the right to re-integration-based method, the weight vector, resulting in a more reasonable weight vector. The experimental results show the feasibility and effectiveness of the method. (4) proposed an improved network the attack performance assessment method based on gray theory. The method to solve when clustering coefficient no significant difference in the performance of network attacks gray evaluation process, generally gray assessment evaluation object can not be accurately assessed. The experimental results show the feasibility and effectiveness of the method.
