Control: 8.1.4.1 Ensure That Microsoft Defender for Containers Is Set To 'On'

Description

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Note: Microsoft Defender for Container Registries ('ContainerRegistry') is deprecated and has been replaced by Microsoft Defender for Containers ('Containers').
