Continuous Monitoring: Continuously monitor traffic and requests for anomalies, leveraging tools like Service Mesh (e.g., Istio) for deep visibility and policy enforcement. How it applies to microservices: ● Authentication and authorization are performed on every request, regardless of its origin. ● mTLS is enforced between microservices to ensure both client and server are

Short answer: uthenticated before communication happens. Service Meshes (like Istio) can help implement Zero Trust by automating identity verification, traffic encryption, and access policies across microservices.

Real-world example (ShopNest)

ShopNest splits Catalog, Cart, Order, and Payment into services so teams can deploy catalog changes without redeploying payments.
