Announcing the Cloud Security Alliance on AWS Compliance Guide
AWS Security Assurance Services is announcing the release of the Cloud Security Alliance (CSA) Compliance Guide on Amazon Web Service (AWS), a new resource that maps the 17 control domains and 207 control objectives of the Cloud Controls Matrix v4.1 (CCM) to AWS services and recommended implementation practices. The guide is intended to help organizations using AWS plan, implement, and evidence the controls relevant to their CCM scope, including those pursuing or maintaining CSA STAR certification.
What is the Cloud Controls Matrix?
The Cloud Security Alliance is a not-for-profit organization dedicated to defining and raising awareness of best practices for cloud security. AWS maintains CSA STAR Level 2 certification, which couples the requirements of ISO/IEC 27001:2022 with the CCM. The CSA STAR documentation and the AWS Consensus Assessments Initiative Questionnaire (CAIQ) are available to AWS customers through AWS Artifact.
The CSA Cloud Controls Matrix is a cybersecurity controls framework developed by the CSA that provides a detailed set of security controls mapped across multiple domains (such as audit and assurance, identity and access management, and encryption and key management) specifically designed to assess and manage security risks in cloud computing environments. The CCM is cloud agnostic, designed to be applicable to any cloud service provider or deployment model, such as infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS), regardless of the underlying technology or vendor, providing universal security controls that organizations can apply across cloud platforms.
Responsibility models
CCM defines its own Shared Security Responsibility Model (SSRM) with three categories: Cloud service provider (CSP)-owned, customer-owned, and shared (independent or dependent). The guide recommends using the SSRM together with the AWS Shared Responsibility Model. For controls that AWS owns, the guide points to AWS attestations available through AWS Artifact (for example, SOC reports, ISO certificates, and the CSA STAR attestation) as inherited evidence. For controls that customers own or share, the guide describes how to implement and evidence them using AWS services. Using a CSA STAR–certified AWS service doesn’t by itself make a customer workload compliant. Customers remain responsible for configuring services, managing access, protecting data, and implementing additional controls based on their environment, risk assessments, and regulatory obligations. The guide is informational and doesn’t replace the AWS compliance documentation and certifications available through AWS Artifact.
What’s inside the guide
For each control, the guide states applicability, describes how organizations can implement the control on AWS, identifies common pitfalls, and lists examples that can be used as evidence during an assessment.
