A Study of Cloud Security Frameworks for Safeguarding Multi-Tenant Cloud Architectures

Multi-tenancy in cloud computing allows multiple tenants to share resources efficiently, offering cost-effectiveness and scalability.However, this architectural design introduces complex security challenges, necessitating robust frameworks and strategies to safeguard sensitive data and maintain isolation among tenants.This paper explores multi-tenancy security concerns and solutions, emphasizing data isolation, unauthorized access prevention, and compliance with regulations.Key techniques, such as virtual and organic multitenancy and data storage strategies, ranging from separate applications to shared databases, are analyzed.Furthermore, security frameworks such as the Shared Responsibility Model, Identity and Access Management (IAM), data protection mechanisms, and network security are discussed.Advanced technologies, including confidential computing and homomorphic encryption, are highlighted for their potential to enhance security in multi-tenant environments.The paper underscores the importance of addressing tenant isolation, data encryption, compliance requirements, and availability risks to ensure a secure and resilient multi-tenant cloud infrastructure.
