# NetworkPolicies

Kubernetes NetworkPolicies are an important measure to secure your kubernetes apps and clusters.
When applied, they restrict the traffic to your services.
This protects other deployments in your cluster or other services in your deployment to get compromised when one
component is compromised.

We ship a default set of Otterize ClientIntents via
[Otterize intents operator](https://github.com/otterize/intents-operator) which translates intent-based access control
(IBAC) into kubernetes native NetworkPolicies.

This requires the Otterize intents operator to be installed.

```yaml
security:
  otterizeIntents:
    enabled: true
```
