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; receiving a connection request for the shared data source from a customer of the set of customers, the connection request having a cryptographic key associated with the customer; creating a trusted compartment for the customer responsive to an authentication of the cryptographic key; receiving a data request from the customer and validating the data request using a sensitivity index; processing the data request using a buffer pool frame and the private partition corresponding to the customer; and creating an entry in a log corresponding to the customer pursuant to the processing.
