Abstract: With the advent of the information age, information systems are facing more and more security attacks, and the loss is also increasing, the information security issues accompanied with information island, data sharing and other issues of governance are becoming increasingly prominent. Information security protection has become increasingly difficult,and it is more difficult to solve the above problems systematically with taking stop-gap measures as before.Therefore, it is necessary to analyze and design the security system accompanied with the information planning and the framework design, so as to truly realize the "top-down" enterprise information security architecture planning and design,and guide the information security work. Based on the existing mainstream enterprise informationization planning methods and the related security architecture models, methods or frameworks in informationization planning, this paper proposes a SADM security architecture development model based on EISA and TOGAF ADM frameworks, which provides a reference for enterprise informationization planning and architecture design, and gives an early exploration for the follow-up establishment of the security architecture development method system.
