9.1.4.1 Ensure That Microsoft Defender for Containers Is Set To 'On'
Information
Microsoft Defender for Containers helps improve, monitor, and maintain the security of containerized assets-including Kubernetes clusters, nodes, workloads, container registries, and images-across multi-cloud and on-premises environments.By default, when enabling the plan through the Azure Portal, Microsoft Defender for Containers automatically configures the following components:
- Agentless scanning for machines
- Defender sensor for runtime protection
- Azure Policy for enforcing security best practices
- K8S API access for monitoring and threat detection
- Registry access for vulnerability assessment
Note: Microsoft Defender for Container Registries ('ContainerRegistry') is deprecated and has been replaced by Microsoft Defender for Containers ('Containers').
Enabling Microsoft Defender for Containers enhances defense-in-depth by providing advanced threat detection, vulnerability assessment, and security monitoring for containerized environments, leveraging insights from the Microsoft Security Response Center (MSRC).
