How do organizations secure communication between microservices in containerized applications?

One method to secure communications between microservices in containerized applications is to use Transport Layer Security (TLS) protocols. This can involve implementing mutual TLS (mTLS) where each service has its own client and server keys for secure communication. Additionally, service mesh tools like Istio or linkerd can provide features for encryption, authentication, and authorization to enhance security between microservices. Implementing network policies and access controls within the container orchestration platform can also help secure communication between microservices.
