Istio lets you configure custom policies for your application to enforce rules at runtime such as:
- Rate limiting to dynamically limit the traffic to a service
- Denials, whitelists, and blacklists, to restrict access to services
- Header rewrites and redirects
Istio also lets you create your own policy adapters to add, for example, your own custom authorization behavior.
You must enable policy enforcement for your mesh to use this feature.
