Abstract

The proliferation of multi-cloud environments, driven by the need for flexibility, redundancy, and cost efficiency, has introduced new challenges in managing security, compliance, and risk. This chapter explores integrative approaches to auditing within multi-cloud infrastructures, highlighting frameworks, tools, and methodologies necessary to ensure robust security and regulatory alignment. It examines key components such as identity and access management, data encryption, network security, and continuous monitoring. Additionally, the chapter outlines auditing practices for security and compliance, referencing international standards like NIST and GDPR. Risk mitigation strategies are discussed through real-world case studies, including risk assessment models and continuity planning. The discussion underscores the need for cohesive auditing mechanisms to address the complexity and fragmentation inherent in multi-cloud systems. By adopting a holistic audit perspective, organizations can safeguard critical assets, meet compliance demands, and build resilient digital ecosystems.
