Ensuring data protection within multi-tenant databases built on cloud infrastructure

Cloud computing has swiftly become a prominent trend in the technology industry, owing to its various benefits such as scalability, high availability, and cost-effectiveness. Consequently, an increasing number of organizations are shifting their operations to cloud-based environments. It is anticipated that cloud technologies will soon form a foundational component of nearly every enterprise. This transformation has significantly influenced sectors like Software as a Service (SaaS), where traditional Database Management Systems (DBMSs) have transitioned into Cloud-based DBMSs (CDBMSs). Alongside this evolution, there has been a movement from conventional single-tenant database structures to multi-tenant architectures, which allow for more efficient utilization of infrastructure and resources. However, despite these benefits, many organizations are still hesitant to adopt multi-tenant database systems due to persistent concerns over data security. The practice of storing data from multiple tenants on the same server—or even within shared tables—introduces considerable risks related to unauthorized access. In response to these concerns, the current research centers on database security in cloud settings, with a specific focus on the unique challenges associated with multi-tenant systems.
