It is a complex engineering to protect the security of information network (info-net), so it is necessary to study out a new security control architecture and model in the view of systemic control. According to the characteristics and security demands of info-net, a new security control viewpoint and its architecture based on components is proposed, the security control system is built, and details about the structure of control framework, its various types, and functions and propagation modes of security control components are introduced, then the features of the control system are summarized in the end
