Abstract
With the construction of the security and stability control system (SSCS), the situation of cyber attack facing the stability control system is becoming more and more severe. Once a cyber attack causes the security and stability business to fail, serious consequences are caused. Firstly, the hierarchical structure of the SSCS is analyzed. Then, the attack tree models of the cyber protection units are established. Combined the fuzzy analytic hierarchy process to establish a successful probability model of cyber attack, a risk assessment method of cyber attack for the SSCS is proposed. Finally, the effectiveness of the proposed method is verified with a standard system.
Keywords
