Security conditions for information flows by memory within the mrosl DP-model
Some sufficient conditions for security of information flows by memory are analysed within a mandatory entity-role security model of access and information flows control in OS Linux set (MROSL DP-model). The implementation of this conditions provides, firstly, a mandatory integrity control (MIC) preventing any modification (via a proper information flow by memory) of entities with a certain integrity level by a subject-session with a small integrity level, and, secondly, a mandatory access control (MAC) preventing information flows by memory from entities with a high level of confidentiality to entities with a low level of confidentiality.
