Title: CROSS-TENANT DATA LEAKAGE ISOLATION
Abstract:
A method and proxy device for cross-tenant data leakage isolation in a multi-tenant database are provided. The method includes monitoring, by a proxy device, traffic flows between a server executing at least one cloud-based application and the multi-tenant database, wherein the proxy device is communicatively connected between the server and the multi-tenant database; capturing, by the proxy device, at least a request to access the multi-tenant database, wherein the request is communicated using a database-specific protocol; analyzing the request to determine if the request is legitimate; upon determining that the request is not legitimate, modifying the request to point to a global-tenant table and to designate a unique tenant identifier, wherein the unique tenant identifier corresponds to a tenant-specific table name designated in the global-tenant table; and sending the modified request to the multi-tenant database using the database-specific protocol.
