The network component of the transition from monolithic application architecture to microservices is considered. The dynamics of the attack surface increase during the transition to microservice architecture is presented on the example of an application designed to keep a centralized record of server equipment and fix the employees responsible for its operation. Measures aimed at increasing the security of the network infrastructure of container orchestration systems are proposed.
