Continuous Monitoring: Continuously monitor traffic and requests for anomalies,?

Short answer: leveraging tools like Service Mesh (e.g., Istio) for deep visibility and policy enforcement.

Explain a bit more

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