Abstract: A computer security system automatically updates an access status and a level of access privilege for each user based on outside feeds related to current status of the user with respect to an organization, such as a business or school and the membership of the user in a group or department within the organization. A unique user identifier is assigned to each user across all computing systems. The computing system retains the relationship between the user and the user identifier even after the user's access to the computing system is terminated. The user may be reassigned the same user identifier should the user again be granted access to the system resources. The computing security system may be implemented as an overlay to an existing resource allocation system, such as the RACF system commonly found on many mainframe computers and may allow decentralization of certain security functions.
