Prisma Cloud Compute Compliance enforcement for hosts covers several aspects to ensure a secure and compliant host environment, particularly within containerized environments. These include:

• Docker daemon configuration files: Ensuring that Docker daemon configuration files are set up according to best security practices is crucial. These files contain various settings that control the behavior of the Docker daemon, and misconfigurations can lead to security vulnerabilities.
• Docker daemon configuration: Beyond just the configuration files, the overall configuration of the Docker daemon itself is critical. This encompasses runtime settings and command-line options that determine how Docker containers are executed and managed on the host.
• Host configuration: The security of the underlying host on which Docker and other container runtimes are installed is paramount. This includes the configuration of the host's operating system, network settings, file permissions, and other system-level settings that can impact the security of the containerized applications running on top.

By focusing on these areas, Prisma Cloud ensures that not just the containers but also the environment they run in is secure, adhering to compliance standards and best practices to mitigate risks associated with containerized deployments.

To specifically target running containers with a Cloud Native Application Framework (CNAF) policy in Prisma Cloud, the administrator should scope the policy to Image names. By doing so, the policy will apply to containers based on the images they were created from, allowing for precise targeting of security policies to specific containers. This approach is part of Prisma Cloud's capabilities to provide granular security controls for containerized environments, ensuring that policies are effectively applied to the relevant containers​​.

The Defender type "Container Defender - Linux" in Prisma Cloud is typically deployed as a container. This deployment method allows the Defender to integrate seamlessly into containerized environments, providing runtime protection and monitoring for container activities. By running as a container, the Container Defender can leverage the native capabilities of the container orchestration platform, such as Kubernetes, to provide security features like threat detection, vulnerability management, and compliance enforcement within the containerized environment. This approach ensures that the security protections are closely aligned with the dynamic and scalable nature of containerized applications.
