Extension to Military Security Model

The military security model (MSM) is a multilevel security model which used to control information flows within an information system with secret (such as government department, military etc.). In the old model, it depends on product lattice of linear lattice and subset lattice for information flow control. But relationships described in this model exists drawbacks in applications. In the new model, the product lattice which is a sensitivity lattice multiplying by organization level lattice is mapped to level relations with sensitivity within an organizations. Then, a more proper relationships which is multiplying the product lattice by lattice of information subset are formed for access control and flow control. So it make the new model more suitable to control the information flow security for information systems of military, government departments or various organizations.
