Abstract: A method and system for controlling access to data. Each dataset of L datasets is stored, via storage access controller (SAC) software external to an operating system, on at least one physical storage device. Each dataset is independently accessible in accordance with an access permission type assigned to each dataset independently selected for each dataset from N unique access permission types. N?2 and L?N. The L datasets and a file integrity table (FIT) are stored in a file system of the operating system. The FIT includes the L datasets, a path that locates each dataset in the file system, and an access permission type assigned to each dataset. Control of access to each dataset stored on the at least one physical storage device is configured in the SAC to enforce, by the SAC, access to each dataset in accordance with the access permission type assigned to each dataset.

N?2 and L?N. Control of access to each dataset stored on the at least one physical storage device is configured to enforce, via the SAC, access to each dataset in accordance with the access permission type assigned to each dataset. The operating system is unable to provide the control of access to each dataset to which access is enforced by the SAC in accordance with the access permission type assigned to each dataset and which is stored on the at least one physical storage device.
