Abstract

With the rapid development of cloud computing technology, the traditional boundary-based network security model has been unable to cope with increasingly complex network threats. As a new security concept, zero-trust security model has gradually attracted attention. This study aims to explore the technical implementation path of zero-trust security model in cloud computing environment, so as to solve the key problems such as authentication, access control and data protection in the current cloud computing environment. Specific methods include building user authentication mechanisms based on behavior analysis, introducing real-time risk assessment algorithms to optimize access decisions, and using software-defined networks to achieve fine-grained traffic control. Experimental results show that the solution can significantly improve the security and flexibility of the cloud computing environment, while reducing the potential attack surface. The main innovation of this study is to deeply integrate the zero-trust concept with the cloud computing scenario, propose a security policy fr amework adapted to the dynamic environment, and provide theoretical support and technical reference for the design of future cloud computing security architecture.
