Policy management in Kubernetes clusters is simplified by Microsoft Defender for Containers

Policy management in Kubernetes clusters is a critical aspect of ensuring the security and compliance of containerised applications. Kubernetes provides various tools to manage policies, but it can be a daunting task for teams to create, enforce, and monitor policies at scale.

Defender for Containers protects your Kubernetes clusters by continuously assessing them to get visibility into misconfigurations and help mitigate identified threats. To get insight into the workload configuration on the cluster, the Azure Policy for Kubernetes is deployed as part of the Defender for Containers plan.

The Azure Policy for Kubernetes extends the Gatekeeper v3 admission controller webhook for OPA. Gatekeeper is needed to check if the policy is correct before enforcing it. On Azure Kubernetes Service (AKS), it is deployed as an add-on. For Arc Enabled Kubernetes, which includes on-premises clusters and clusters hosted in Google Cloud or Amazon Web Services, it is deployed as an extension.

Defender for Containers is a tool that simplifies policy management in Kubernetes clusters. It is a native Kubernetes security solution that enables teams to protect their containerised applications by automating policy creation, enforcement, and monitoring.
