Among other things, embodiments of the present invention provide cloud administrators with an easy to use customizable, configurable security constraint builder/tool with a built-in multi-tenant/customer enabled security model. Moreover, embodiments of the present invention enable cloud administrators to set up, configure, and manage tenants/customers and their private shards with their own security constraints. The output of this tool greatly eases the time to create an invisible (e.g., software) wall of separation for multiple tenants/customers in a shared cloud infrastructure. ## Claims ### Claim 1 A computer-implemented method for building data security in a networked computing environment, comprising: partitioning a shared data source of the networked computing environment into a set of private partitions pertaining to a set of customers;
