How do you enable least-privilege access for Service Mesh?

Enabling least-privilege access for a service mesh helps to secure your microservices by ensuring that each service only has the permissions it needs to function. This approach minimizes the potential attack surface within your application architecture. Implementing least-privilege access typically involves defining fine-grained access policies that control the communication between services.

To demonstrate how to enable least-privilege access in a service mesh, let's take an example using Istio, a popular service mesh implementation.

apiVersion: security.istio.io/v1beta1 kind: AuthorizationPolicy metadata: name: productpage-view namespace: bookinfo spec: rules: - from: - source: principals: ["*"] - to: - operation: methods: ["GET"] paths: ["/productpage"]
