A knowledge expression method of scada network attack and defence based on factor state space

To solve the problem of knowledge expression in SCADA network attack and defence system, a new knowledge expression method of SCADA network attack and defence based on factor state space is presented. Combined with factor space definition and the formal description of factor state space expression and analyzing attack factors, skill and attack aim, analysis and expression method of network attack and defense factors is developed. On the basis of analysis and expression of network attack and defense factors, equivalence class partition formal description is presented. For illustration, an attack simulation experiment is utilized to show the feasibility of the proposed method in solving network attack and defence knowledge expression. By introducing factor space canes, objects class can be represented. Empirical results show that our proposed method can effectively improve accuracy of attack classification. Knowledge expression method based on factor state space can effectively solve complexity of knowledge expression in network attack and defence system and provides a new method for solving similar application.
