Abstract
A method for implementing a mandatory access control model in operating systems which natively use a discretionary access control scheme. A method for implementing mandatory access control for a plurality of computers, the system comprising information assets, stored as files on the computers, and a network communicatively connecting the computers, wherein each of the computers includes an operating system that uses a discretionary access control policy, and wherein each of a subset of computers includes a software agent component operable to intercept a request for a file operation on a file from a user of one of the computers including the software agent, determining whether the file is protected, if the file is protected, altering ownership of the file from the user to another owner, and providing access based on a mandatory access control policy.
