A Research On Security Management Model In Information Systems Lifecycle Of Power Grid Enterprise

Including the power grid enterprises,information technology has been completely integrated into every enterprise nowadays.Production and management mode of power grid enterprises are changing with the development of information systems,production and management works are more and more convenient,fast,and efficient.But with the rapid development of IT technology and the emergence of new technology such as cloud computing,high-speed mobile networks,information security issue is also exposed,and trend to be increasingly serious.In this paper,it is believed that information system security vulnerabilities,authorized use,disclosure of sensitive information and destruction of information system by vulnerabilities are the main information system threat to power grid enterprise.The power grid enterprise information system life cycle includes application,approval,construction,acceptance testing,operation and maintenance phase.This article designed the whole life cycle of information system security management system and the corresponding control measures and tools.At the same time,this article also focuses on the weaknesses of power grid enterprises in the information security management,which is in information system design,development and test,proposes the corresponding reference standard and provides the guidance for power grid enterprise information system life cycle management.As a result made the life cycle security management scheme more practical,improve information security protection ability and the security level of enterprise information system.
