<p>I am working on solution wherein I have one sidecar alongwith main container in one pod , sidecar is working as a proxy for traffic going out of the pod.
Do I need any kind of encryption/TLS security between sidecar and main container if yes then how can I achieve ?</p>

<p>It depends on your security requirements. Traffic between the main container and Istio sidecar <a href="https://stackoverflow.com/questions/55443582/is-the-traffic-between-sidecar-and-main-process-encrypted-in-istio">is not encrypted</a>. I guess if you are, for example, getting started with Istio or a similar solution and don't know if this is required, it is very likely you don't need that, though.</p>
