Your organization must follow the Payment Card Industry Data Security Standard (PCI DSS).

To ensure compliance with the Payment Card Industry Data Security Standard (PCI DSS) at the infrastructure-as-a-service (IaaS) level within Google Cloud, it's essential to have continuous monitoring and assessment tools that can detect deviations from compliance requirements.​

Option A: Creating data profiles and configuring Data Discovery jobs in Google Cloud Sensitive Data Protection focuses on identifying and analyzing sensitive data but does not directly address infrastructure compliance monitoring.​

Option B: Downloading the latest PCI DSS report from the Compliance Reports Manager provides a static compliance report but does not offer real-time detection of deviations within your specific environment.​

Option C: Utilizing Assured Workloads helps in creating environments that meet specific compliance requirements, but migrating existing projects into such folders does not actively detect deviations; it primarily ensures that new workloads comply with predefined policies.​

Option D: Activating Security Command Center (SCC) Premium and leveraging its Compliance Monitoring capabilities allows for continuous assessment of your Google Cloud environment against PCI DSS requirements. SCC can identify misconfigurations, vulnerabilities, and compliance violations in real-time, providing actionable insights to address any issues promptly.​

Therefore, Option D is the most effective approach to detect deviations at the IaaS level in preparation for a PCI DSS audit.​
