| With the rapid development of information technology and industrialization,the integration of industrial control system and modern information technology has become an inevitable trend,breaking the traditional closed and isolation,and gradually transforming into an open and interconnected system.Since then,the security situation of industrial control system has become more and more serious,and it has gradually become a new important target for network attackers.In recent years,risk events such as equipment failure and information tampering caused by network security attacks on industrial control systems have occurred frequently,causing huge economic losses to enterprises.Therefore,strengthening the network security construction of industrial control system has become an urgent problem to be solved.However,network security projects belong to the forefront of science and technology,with high technical difficulty and complexity,and there are many uncertain factors.Therefore,it is particularly important to strengthen the risk management research of network security projects.This paper takes the risk management of the situation awareness project of industrial control system of enterprise a as the research object,deeply analyzes the various risks faced in the implementation of the project,and puts forward specific risk countermeasures.First of all,the related theories of project risk management are summarized,which lays a theoretical foundation for the research of this paper.Secondly,the construction background,construction scheme,team composition and other information of the situation awareness project of enterprise a are introduced in detail,and the risk management plan is formulated according to the actual situation.Next,the risk management of the situation awareness project of enterprise a is deeply studied from four aspects:risk identification,risk assessment,risk response and risk monitoring.In the risk identification,a total of 6 categories and 19 risk factors were identified through brainstorming and Delphi methods,and further through the combination of qualitative and quantitative analysis,expert judgment and analytic hierarchy process were used to calculate and analyze all risk factors,and the risk factors of the project were ranked according to the risk value of different risks.Finally,countermeasures were formulated one by one according to the impact of risks on the overall project,And conduct real-time risk monitoring in the project operation to achieve effective management of project risk and ensure the successful implementation of the project. |
