Cloud storage services offer significant advantages for organizations seeking scalable and cost-effective data storage solutions. However, regulated industries such as healthcare, finance, and government face unique security and compliance challenges when adopting cloud storage. This paper addresses these challenges in the context of Google Cloud Storage, examining the platform's security features, compliance certifications, and best practices for meeting regulatory requirements. We explore topics including data encryption, access control, audit logging, data residency, and disaster recovery, providing practical guidance for organizations navigating complex compliance frameworks such as HIPAA, PCI DSS, and GDPR. Furthermore, this paper presents implementation code studies demonstrating how to configure Google Cloud Storage to meet specific security and compliance needs, ensuring data protection and regulatory adherence in sensitive industries.
