4 Basic principles of security protection

The security protection of critical information infrastructure shall be based on the classified protection system of cybersecurity, and key protection shall be provided based on the following basic principles.

——Overall prevention and control centered on critical business. The security protection of critical information infrastructure aims to protect critical businesses, and provides systematical security designs for one or more network(s) and information system(s) involved in the businesses, in order to build an overall security prevention and control system.

——Dynamic protection guided by risk management. Continuously monitor and dynamically adjust security control measures based on the security threat situation faced by critical information infrastructure, form a dynamic security protection mechanism to timely and effectively prevent and respond to security risks.

——Coordinated defense based on information sharing. Actively build a joint protection mechanism for information sharing and collaborative collaboration with extensive participation from relevant parties, and enhance the ability of critical information infrastructure to respond to large-scale network attacks.

5 Main contents and activities

The security protection of critical information infrastructure covers six aspects: analysis and identification, security protection, detection and evaluation, monitoring and warning, active defense and incident treatment.


a) Analysis and identification: carry out activities such as business dependency identification, critical asset identification and risk identification around the critical businesses of critical information infrastructure. This activity is the basis for security protection, detection and evaluation, monitoring and warning, active defense and incident treatment.
