mTLS with Istio Service Mesh

Istio can provide mutual TLS (Transport Layer Security) authentication, which ensures that both the client and server are authenticated before communication takes place. This is important for preventing unauthorized access, man-in-the-middle attacks, and data breaches. Istio uses the Envoy proxy to handle all network traffic, which allows it to manage mTLS encryption and decryption for each service. Istio also provides a certificate authority (CA) that can issue certificates for each service, allowing them to authenticate each other.
