Enhanced data security through file access control of processes in a data processing system

A data processing system for controlling the transfer of data from a data processing system to a network comprising:

• means for creating a file list of one or more data files to be controlled;
• means for creating a process list for each data file in the file list, wherein each process list identifies one or more processes executing in the data processing system that has accessed the data file associated with the created process list;
• means for receiving a request from a requesting process executing in the data processing system to transfer data from the data processing system to the network;
• means for determining if the requesting process is identified in one or more created process lists;
• and
• means for, if the requesting process is identified in a created process list, prohibiting the requested transfer of data from the data processing system to the network.

An article of manufacture comprising machine-readable medium including program logic embedded therein that causes control circuitry in a data processing system for controlling the transfer of data from a data processing system to a network to perform the steps of:

• creating a file list of one or more data files to be controlled;
• creating a process list for each data file in the file list, wherein each process list identifies one or more processes executing in the data processing system that has accessed the data file associated with the created process list;
• receiving a request from a requesting process executing in the data processing system to transfer data from the data processing system to the network;
• determining if the requesting process is identified in one or more created process lists;
• and
• if the requesting process is identified in a created process list, prohibiting the requested transfer of data from the data processing system to the network.
