Research on security monitoring of distributed heterogeneous network environment based on microservice architecture

In a distributed network environment, multiple mutually independent trust domains are formed between different enterprises. During network access, access requests for resources may come from local trust domains or from field trust domains. Therefore, when a user from a local trust domain accesses a resource from a foreign trust domain, or a user from a foreign trust domain accesses a resource from a local trust domain, it involves cross-trust domain authentication and session key negotiation. In this paper, we propose a distributed heterogeneous network environment security monitoring study based on microservice architecture, which collects and analyzes the horizontal traffic of microservices in real time to monitor the network performance. By collecting the virtual network packet capture data under the microservice architecture of the SouthNet cloud environment, the network communication quality between microservice applications is monitored and alerted in real time, and the network communication fault localization between microservice nodes is supported to assist in troubleshooting. The experimental results show that the distributed heterogeneous network environment security monitoring system based on microservice architecture can improve the flexibility, scalability and security of the system, which is applicable to the monitoring needs in different fields.
