Cloud Security Checklist: AWS, Azure & GCP

A cloud security checklist is a structured framework of security controls and best practices that organizations should implement to protect their cloud infrastructure. Based on CIS Benchmarks and CSA Cloud Controls Matrix (CCM), it covers identity management, network security, data protection, logging, and incident response. According to Gartner, through 2025, 99% of cloud security failures will be the customer's fault-making checklists critical.

Yes. The checklist includes platform-specific sections for AWS, Azure, and GCP, plus a dedicated multi-cloud section covering cross-cloud identity federation, unified SIEM integration, consistent security policy enforcement, and centralized compliance monitoring. Each control is mapped to the equivalent service across all three platforms.

CIS Benchmarks provide granular technical configuration guidance (e.g., specific AWS Config rules). This checklist operates at a higher level-organizing CIS controls into actionable categories with business context, prioritization guidance, and compliance mapping. Think of it as an executive layer on top of CIS Benchmarks that helps teams prioritize what to implement first.

The checklist maps cloud security controls to ISO 27001:2022 (Annex A.5-A.8), SOC 2 Type II (CC6, CC7, CC8), PCI DSS v4.0 (cloud-specific requirements), CIS Benchmarks v2.0 for each platform, and CSA Cloud Controls Matrix v4. Each control includes the specific compliance requirement reference.

Absolutely. The checklist includes a pre-migration security assessment section and a post-migration validation framework. It's designed to be used during the planning phase (security requirements), implementation phase (configuration validation), and operational phase (ongoing compliance monitoring).

Cloud security configurations should be continuously monitored using CSPM tools. However, a comprehensive manual review using this checklist should be conducted quarterly, after any significant infrastructure changes, and before compliance audits. The checklist includes a review schedule template aligned with major compliance frameworks.
