Database Security in Cloud Environments: Exploring Multi-Tenant Risks, Data Isolation Challenges, and Compliance Mechanisms in Hybrid and Public Clouds

Abstract

This study investigates the multifaceted challenges of database security in cloud environments, focusing on multi-tenant risks, data isolation strategies, and compliance mechanisms in hybrid and public cloud architectures. Employing a mixed-methods approach, the research synthesizes existing literature, analyzes hypothetical datasets, and evaluates security frameworks to identify vulnerabilities and propose mitigation strategies. Key findings reveal that multi-tenant architectures amplify risks of unauthorized access, data leakage, and compliance violations, particularly in public clouds. Data isolation challenges stem from inadequate logical separation and encryption practices, while compliance requires robust auditing and governance frameworks. The study underscores the need for adaptive security models and standardized compliance protocols to safeguard sensitive data. These findings contribute to the theoretical understanding of cloud security and offer practical recommendations for organizations leveraging cloud-based databases.
