Multi-tenancy is to provide services to multiple clients on same physical resources through virtualization. But, at the same time providing security to private data of multiple tenants is big challenge. In this paper, the focus is on security and data privacy (isolation) for SaaS applications that are built and deployed on MTAs (Multi-Tenant Architectures). In MTA, a single database is shared with all tenants. Sharing of a database can lead to unauthorized access of tenant's data by another tenant, which is a serious security flaw.
