Abstract
With the rapid development of information technology and the increasing complexity of network attack methods, traditional perimeter-based security protection systems are struggling to address the diverse cyber security threats currently faced. The zero-trust architecture, as an emerging security concept, has gradually garnered significant attention. This study aims to design a cyber security protection system based on the zero-trust architecture to enhance security and reliability in network environments. By conducting an in-depth analysis of the core principles of zero trust, including continuous identity verification, least-privilege access, and dynamic trust assessment, and combining these with practical application requirements, a multi-layered, adaptive security protection fr amework is proposed. This fr amework integrates key technologies such as identity management and access control, behavioral analysis, and threat detection, and optimizes the trust assessment mechanism through the introduction of artificial intelligence algorithms, thereby achieving fine-grained control over users and devices. Experimental results demonstrate that the designed protection system effectively reduces the risk of unauthorized access and significantly enhances the system's resilience against attacks. Moreover, the system exhibits excellent scalability and compatibility in complex network environments, providing a feasible solution for practical deployment. The primary innovation of this research lies in the deep integration of dynamic trust assessment and intelligent analytical techniques, which overcomes the limitations of traditional static defense models and provides theoretical support and technical references for constructing next-generation cyber security protection systems. The research findings hold significant implications for promoting the practical application of zero-trust architecture and improving overall cyber security levels.
