To prevent attackers from reaching resources hosted by other microservices through lateral movement, authorization policies are required to restrict unauthorized access across services. Existing policy generation approaches depend on manual policy configuration, document analysis, historical log analysis, and static code analysis. However, these approaches impose substantial policy maintenance costs, require the availability of supporting documents and logs, and may cause path explosion problems. To address these challenges, this study proposed Adaptive Unified Security Policy Orchestration (AUSPO). It consisted of three core technologies: (1) A microservice communication data collection method built on eBPF-based monitoring(MseBPF) to capture dependency data among microservices to infer inter-service invocation logic; (2) A policy generation algorithm based on DBSCAN clustering(DBPO), which can translate the conversion of communication data into actual policies and generate access control policies between services (3) An cremental policy update mechanism based on the Pod lifecycle (PodUp), which performs policy analysis exclusively on Pods involved in microservice iteration, providing an efficient approach for subsequent policy updates. We deploy AUSPO in the publicly available Bookinfo and Sockshop microservice environments. Experimental results show that the proposed method can generate fine-grained access control rules to block all unauthorized malicious requests. Additionally, it introduces an average processing latency overhead of no more than 3% for microservices, and completes policy updates with an analysis time of no more than 29% of that consumed in initial policy generation.
