Abstract. A much used confidential leveling mandatory access control model is studied. Inconsistency and principle disadvantages of the model are revealed which do not allow for creation of a safe system based on it. New integrity and accessibility model, as well as consistent mandatory access control model are developed and justified; application of the latter model is shown to prevent confidential information leakage and to solve the problems of information integrity and accessibility.
