The Cloud Security Alliance (CSA) Cloud Controls Matrix (CCM) is the best tool to perform cloud security control audits, as it is a comprehensive framework that provides organizations with a detailed understanding of security concepts and principles that are aligned to the cloud model. The CCM covers 16 domains of cloud security, such as data security, identity and access management, encryption and key management, incident response, and audit assurance and compliance. The CCM also maps to other standards, such as ISO 27001, NIST SP 800-53, PCI DSS, COBIT, and GDPR, to facilitate compliance and assurance activities1.
The General Data Protection Regulation (GDPR) is not a tool, but rather a regulation that aims to protect the personal data and privacy of individuals in the European Union (EU) and the European Economic Area (EEA). The GDPR imposes strict requirements on organizations that process personal data of individuals in these regions, such as obtaining consent, ensuring data security, reporting breaches, and respecting data subject rights. The GDPR is relevant for cloud security audits, but it is not a comprehensive framework that covers all aspects of cloud security2.
The Federal Information Processing Standard (FIPS) 140-2 is not a tool, but rather a standard that specifies the security requirements for cryptographic modules used by federal agencies and other organizations. The FIPS 140-2 defines four levels of security, from Level 1 (lowest) to Level 4 (highest), based on the design and implementation of the cryptographic module. The FIPS 140-2 is important for cloud security audits, especially for organizations that handle sensitive or classified information, but it is not a comprehensive framework that covers all aspects of cloud security3.
ISO 27001 is a standard that specifies the requirements for establishing, implementing, maintaining and continually improving an information security management system (ISMS). An ISMS is a systematic approach to managing information security risks and ensuring the confidentiality, integrity and availability of information assets. ISO 27001 is relevant for cloud security audits, as it provides a framework for assessing and improving the security posture of an organization. However, ISO 27001 does not provide specific guidance or controls for cloud services, which is why ISO 27017:2015 was developed as an extension to ISO 27001 for cloud services4. References :=
