Abstract
Means and methods of securing protected system files in a data processing system are disclosed, wherein the information determining access rights of system users to the protected systems files remains at all times within a secure processor. Provision is also made for allowing the display or labeling of protected data files only when markings consistent with the security level of such files are also displayed or included in the label. Furthermore, provision is also made for limiting the access rights of users to protected system files based on a comparison between the formats associated with said files and the function or subsystem performing operations on behalf of the users.
