The enterprise information security framework consists of three main layers from top to bottom: “security governance, risk management and compliance layer”, “security operation and maintenance layer”, “basic security service and architecture layer”. Security management, risk management and compliance layer are the theoretical basis of the latter two; the security operation and maintenance layer is the management of the whole process of the security life cycle; the basic security service and architecture layer are the technical requirements and functions of enterprise information security construction. Implementer.
(1) Total governance, risk management and compliance
