An overall security understanding and method of cyberspace based on connection and security entropy

Summary

The characteristics of the cyberspace itself, such as diversity of structure, random access, and multi-domain linkage, make the security perspective, connotation and elements of its security situation need to constantly adapt to the development and changes of new network forms.On the basis of analyzing the current situation of cyberspace security development at home and abroad, it points out the security risks and challenges facing the current cyberspace;Based on the analysis and discussion of cyberspace security issues based on connections, the overall cyberspace security concept of "D-I-D-E network data-driven loop" is proposed, and its application value is discussed.The purpose is to propose a solution to security problems from a new perspective, further expand and supplement the current cyberspace security cognition, and provide theoretical reference for network information system planning, design, construction and later security enhancement and reinforcement.

4 Conclusion

Cyberspace is a kind of information infrastructure including the Internet, Internet of Things, communication network, industrial control network, etc. It is a virtual and real space formed by the interconnection and interaction of "human-machine-object".Network connection is the basic premise of the network, data exchange is the basic function of the network, and drive execution is the basic goal of the network.The network not only connects information data to cyberspace for processing and exchange, but also connects real entities to cyberspace for execution and feedback.Therefore, on the basis of enhancing the value and role of real entities in the network, cyberspace realizes a new space where virtual and real are closely connected and integrated, driven by network connections.

With the accelerated iteration and deployment of information technology and equipment, the network scale has been further expanded
