Zero-Trust Architecture in Java Microservices

Securing inter-service communication and data access has become crucial as microservices become the architectural standard in enterprise software development. In dynamic, cloud-native systems, traditional perimeter-based security solutions are no longer adequate. The Zero-Trust Architecture (ZTA) in Java-based microservices is thoroughly examined in this study. We go over the fundamentals of ZTA, look at how it applies to microservices, and offer thorough methods for implementing zero-trust policies with industry-standard frameworks and tools like OAuth 2.0, Istio, and Spring Security. Additionally, a case study showing how ZTA is implemented in a distributed Java microservices application is provided.
