Building data security in a networked computing environment

A system for building data security in a networked computing environment, comprising:

• a memory medium comprising instructions;
• a bus coupled to the memory medium;
• and
• a processor coupled to the bus that when executing the instructions causes the system to:
• partition a shared data source of the networked computing environment into a set of private partitions pertaining to a set of customers;
• associating a set of composite rule sets with the set of private partitions, the composite rule sets defining an identity index of the set of customers to which the private partitions pertain;
• receive 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;
• create a trusted compartment for the customer responsive to an authentication of the cryptographic key;
• receive a data request from the customer;
• determine at least one of the set of private petitions in which the requested data is to be stored or retrieved based on the data request;
• validate the data request by determining whether an identity index of the customer is of a degree sufficient to process the data request based upon a sensitivity index of data requested by the data request and the identity index from the composite rule set associated with the determined at least one of the set of private partitions;
• process the data request using a buffer pool frame and the determined at least one of the set of private partitions;
• and
• create an entry in a log corresponding to the customer pursuant to the processing of the data request.

A computer program product for building data security in a networked computing environment, the computer program product comprising a nontransitory computer readable storage media, and program instructions stored on the non-transitory computer readable storage media, which when executed by a computing device cause the computing device to:

• partition a shared data source of the networked computing environment into a set of private partitions pertaining to a set of customers;
• associate a set of composite rule sets with the set of private partitions, the composite rule sets defining an identity index of the set of customers to which the private partitions pertain;
• receive 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;
• create a trusted compartment for the customer responsive to an authentication of the cryptographic key;
• receive a data request from the customer;
• determine at least one of the set of private petitions in which the requested data is to be stored or retrieved based on the data request;
• validate the data request by determining whether an identity index of the customer is of a degree sufficient to process the data request based upon a sensitivity index of data requested by the data request and the identity index from the composite rule set associated with the determined at least one of the set of private partitions;
• process the data request using a buffer pool frame and the determined at least one of the set of private partitions, the at least one of the set of private partitions corresponding to the customer;
• and
• create an entry in a log corresponding to the customer pursuant to the processing of the data request.

A method for deploying a system for building data security in a networked computing environment:

• providing a computer infrastructure being operable to:
• partition a shared data source of the networked computing environment into a set of private partitions pertaining to a set of customers;
• associate a set of composite rule sets with the set of private partitions, the composite rule sets defining an identity index of the set of customers to which the private partitions pertain;
• receive 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;
• create a trusted compartment for the customer responsive to an authentication of the cryptographic key;
• receive a data request from the customer;
• determine at least one of the set of private petitions in which the requested data is to be stored or retrieved based on the data request;
• validate the data request whether an identity index of the customer is of a degree sufficient to process the data request based upon a sensitivity index of data requested by the data request and the identity index from the composite rule set associated with the determined at least one of the set of private partitions;
• process the data request using a buffer pool frame and the determined at least one of the set of private partitions;
• and
• create an entry in a log corresponding to the customer pursuant to the processing of the data request.
