Multi-tenant data isolation techniques in public clouds assessing the effectiveness of isolation mechanisms

Cloud computing is characterized by its capacity for multiple tenants to share a single cloud infrastructure, which is known as multi-tenancy. Even while it offers cost-efficiency and resource optimization, implementing multi-tenancy raises a number of distinct security challenges. With an emphasis on isolation and access control methods, this paper aims to offer a thorough investigation into the security of multi-tenancy in cloud computing. In this study, the potential dangers that are linked with co-located tenants are investigated, and a variety of measures that can be used to guarantee strong isolation between renters are discussed. Furthermore, the research examines access control methods including Attribute-Based Access Control (ABAC) and Role-Based Access Control (RBAC) to enforce finer-grained access permissions. Both cloud service providers and tenants can enhance cloud security by learning and using effective isolation and access control mechanisms. This will help with multi-tenant setups and overall cloud security.
