The CSA STAR Certification is based on criteria outlined in the Cloud Security Alliance (CSA) Cloud Controls Matrix (CCM) in addition to ISO/IEC 27001 implementation. The CCM is a cybersecurity control framework for cloud computing that covers 17 domains and 197 control objectives that address all key aspects of cloud technology. ISO/IEC 27001 is a standard for information security management systems that specifies the requirements for establishing, implementing, maintaining, and continually improving an information security management system within the context of the organization. The CSA STAR Certification demonstrates that a cloud service provider conforms to the applicable requirements of ISO/IEC 27001, has addressed issues critical to cloud security as outlined in the CCM, and has been assessed against the STAR Capability Maturity Model for the management of activities in CCM control areas1. The CSA STAR Certification is a third-party independent assessment of the security of a cloud service provider and provides a high level of assurance and trust to customers2.

The most useful document for an auditor to review when seeking visibility into the cloud supply chain for a newly acquired Software as a Service (SaaS) solution is the SaaS provider contract. The contract is the legal agreement that defines the terms and conditions of the cloud service, including the roles, responsibilities, and obligations of the parties involved1. The contract should also specify the service level agreements (SLAs), security and privacy requirements, data ownership and governance, incident response and reporting, audit rights and access, and subcontracting or outsourcing arrangements of the SaaS provider2. By reviewing the contract, the auditor can gain insight into the cloud supply chain and assess the risks, controls, and compliance of the SaaS solution.

The other options are not as useful as the SaaS provider contract. Payments made by the service owner are the financial transactions that reflect the fees or charges incurred by using the SaaS solution. They may indicate the usage or consumption of the cloud service, but they do not provide much information about the cloud supply chain or its security and compliance aspects3. SaaS vendor white papers are the marketing or educational materials that describe the features, benefits, or best practices of the SaaS solution. They may provide some general or technical information about the cloud service, but they are not legally binding or verifiable4. Cloud compliance obligations register is a tool that helps customers identify and track their compliance requirements and obligations for using cloud services. It may help customers understand their own responsibilities and risks in relation to the cloud service, but it does not necessarily reflect the compliance status or performance of the SaaS provider5.

The best method to report continuous assessment of a cloud provider’s services to the Cloud Security Alliance (CSA) is through a set of dedicated application programming interfaces (APIs). According to the CSA website1, the STAR Continuous program is a component of the STAR certification that allows cloud service providers to validate their security posture on an ongoing basis. The STAR Continuous program leverages a set of APIs that can integrate with the cloud provider’s existing tools and processes, such as security information and event management (SIEM), governance, risk management, and compliance (GRC), or continuous monitoring systems. The APIs enable the cloud provider to collect, analyze, and report security-related data to the CSA STAR registry in near real-time. The APIs also allow the CSA to verify the data and provide feedback to the cloud provider and the customers. The STAR Continuous program aims to provide more transparency, assurance, and trust in the cloud ecosystem by enabling continuous visibility into the security performance of cloud services.

The other methods listed are not suitable for reporting continuous assessment of a cloud provider’s services to the CSA. The Cloud Controls Matrix (CCM) assessment by a third-party auditor on a periodic basis is part of the STAR Certification Level 2 program, which provides a point-in-time validation of the cloud provider’s security controls. However, this method does not provide continuous assessment or reporting, as it only occurs once every 12 or 24 months2. The tools selected by the third-party auditor may vary depending on the scope, criteria, and methodology of the audit, and they may not be compatible or consistent with the CSA’s standards and frameworks. Moreover, the tools may not be able to report the audit results to the CSA STAR registry automatically or frequently. The SOC 2 Type 2 attestation is an independent audit report that evaluates the cloud provider’s security controls based on the American Institute of Certified Public Accountants (AICPA) Trust Services Criteria. However, this report is not specific to cloud computing and does not cover all aspects of the CCM. Furthermore, this report is not intended to be shared publicly or reported to the CSA STAR registry3.

This situation poses a significant concern for a cloud auditor because it indicates a potential gap in the technical team’s ability to effectively manage and secure the IaaS platform provided by the alternative vendor. Without proper training on the specific features, security practices, and operational procedures of the new platform, the organization may face increased risks of misconfiguration, security vulnerabilities, and inefficiencies in cloud operations. It is crucial for the technical team to have a comprehensive understanding of all platforms in use to ensure they can maintain the security and performance standards required for a robust cloud environment.

References = The concern is based on common cloud auditing challenges, such as controlling and monitoring user access, and ensuring the IT team is equipped to manage the cloud environment effectively12. Additionally, best practices suggest that network segmentation, user authentication, and access control are critical areas to address in a cloud audit3. These principles are widely recognized in the field of cloud security and compliance.
