Mitigate the Security Challenges of Telecom 5G IoT Microservice Pods Architecture Using Istio

Deploying microservices in a Kubernetes cluster is critical in 5G Telecom. However, it also introduces significant security risks. While firewall rules and proxies provide initial security, the default communication mechanisms within Kubernetes, such as unencrypted network traffic and lack of access control, are inherently insecure. This insecurity could compromise sensitive data. Therefore, implementing additional security measures within each microservice pod is not just a recommendation but a crucial step to ensure secure communication within the cluster. So, additional configuration inside each application is needed. 

Istio provides a robust solution to these challenges by effectively managing communication between individual 5G telecom microservice pods. With its control plane, Istio automatically injects a sidecar proxy into individual microservices pods, ensuring secure and efficient communication.
