For a cloud service to be recognized under the CSA Security Trust and Assurance Registry, what must it meet?

The correct answer reflects that for a cloud service to be recognized under the Cloud Security Alliance (CSA) Security Trust and Assurance Registry, it must meet the security requirements established by the CSA. This registry is designed to help organizations assess the security posture of cloud service providers based on specific criteria set forth by the CSA, which include best practices, guidelines, and security principles tailored to the unique nature of cloud services.

These security requirements encompass a broad range of dimensions such as data protection, incident response, governance, and risk management, ensuring that the cloud service meets industry standards for security and trustworthiness. By aligning with the CSA’s security benchmarks, a service can more effectively demonstrate its commitment to robust security practices, thereby fostering greater trust among potential users.

While other options address important areas of compliance, such as GDPR for data privacy, CMMI for process improvement, and PCI DSS for payment data security, they do not specifically pertain to the necessary conditions for endorsement by the CSA. Each of those frameworks has its own set of requirements and purposes but they are not the core focus of the CSA's assurance registry criteria.
