There is a variety of these models that can be discussed, and most include different methods of applying the ISO/OSI security layered model. A few of these models include the Access matrix, the Bell-LaPadula confidentiality model, and the Clark-Wilson integrity model. The Access Matrix is a policy for user authentication, and is used to prevent unauthorized changes being made by otherwise authorized users through the use of object controls.
