Abstract
Methods and systems are provided which control access by a task to an information object in a computer system. The task is authenticated by an authentication procedure to act on behalf of a user. A computer-implemented method includes associating an authentication grade with the authentication procedure, identifying at least one clearance level previously assigned to the user by a clearance administrator, and identifying at least one classification level previously assigned to the information object by a classification administrator. The method then determines the access rights of the task with respect to the information object based at least on the authentication grade, the clearance level, and the classification level. Information about the user's connection to the system may also be considered. The results of the determination are distributed to promote consistent access; rights throughout the system.
