SECURE TAVTM enables authorized users to only manipulate/view information with classification equal to those assigned to a given user. This requires all SECURE TAVTM Data Base users be identified in the Account Table of the TAVTM Data Base, and that the corresponding Account Table entry has at least one valid classification assigned. If a user logs onto the System but is not found in the Account Table, or does not have any classification assigned, that user will be immediately logged out of the SECURE TAVTM system.
