Demystifying Secure Application Communication with Zero Trust and Istio Without Sidecars

Explore the essentials of securing cloud-native application communications within a zero-trust architecture framework in this 37-minute presentation by Lin Sun from solo.io. Delve into the requirements for securing distributed applications across multiple Kubernetes clusters or virtual machines, addressing questions about encryption, unique identities, data integrity, and access control. Learn how mutual TLS (mTLS) meets these security requirements through its handshake and record protocols. Watch a live demonstration of implementing mTLS for applications by simply labeling their namespaces, without requiring application restarts or sidecars, using Istio's ambient mesh. Gain valuable insights into securing modern cloud-native applications and understanding the considerations for multi-cluster environments.
