电力信息物理系统跨域攻击协同防御架构及机制研究
Research of Architecture and Mechanism of Coordinative Defense Methods for Cross-Domain Attacks of Cyber Physical System
摘要
Abstract
The electric power infrastructure of China has developed into a highly informationized,automated,and in-telligent cyber physical integration system.The interaction of cyber and physical not only significantly improves the effi-ciency and performance of power supply,but also introduces new network security threat.Cross-domain attacks that occur-ring in the cyber domain and acting on the physical domain can cause the systematic breakdown of power infrastructure and then lead to large-scale power outages.However,the current isolated cyber side or physical side defense system is difficult to effectively deal with these cross-domain attack threats.This paper introduces the current situation of information and physical cross domain attack threats faced by the power system,elaborates on the shortcomings of traditional defense meth-ods in facing cross domain attacks,proposes a cross domain attack defense architecture based on information and physical collaboration,and designs defense methods from the perspectives of perception,identification,and blocking on the attack time scale.Through example design,it is proven that the proposed information and physical collaboration defense architec-ture can ensure the safe and stable operation of the power system.关键词
