Abstract

With the rapid development of information technology, cybersecurity threats have become increasingly complex and dynamic, rendering traditional network architectures based on perimeter defense inadequate in addressing multifaceted security challenges from both internal and external sources. The Zero Trust Network Architecture (ZTNA), as an emerging security paradigm, emphasizes stringent identity verification and access control for all access requests regardless of environment, offering a novel solution for communication security. This study investigates the application of ZTNA in the field of communication security by analyzing its core mechanisms and technical characteristics. An experimental platform is constructed based on real-world scenarios, integrating theoretical research with empirical analysis to delve into key technologies such as identity authentication, access control, and data encryption under the zero trust fr amework. The findings indicate that ZTNA can significantly enhance the security of communication systems, achieve fine-grained access control, reduce internal threat risks, and maintain high flexibility and adaptability in dynamic environments. Innovatively, this research proposes a behavior analysis-based identity authentication enhancement mechanism that improves the accuracy and reliability of authentication without compromising user experience, providing new perspectives and technical approaches for communication security and promoting the practical application of zero trust principles in real-world communication systems.
