Operational requirements for multilevel security
Proceedings of 9th Annual Computer Security Applications Conference, 2002Multilevel security (MLS) technology offers capabilities to increase the effectiveness, efficiency, and security of operations that rely on information systems. The US unified and specified combatant commands have been surveyed to identify their operational requirements for MLS and near-term solutions to satisfy the common and most pervasive ...

Security constraint processing during multilevel secure database design
[1992] Proceedings Eighth Annual Computer Security Application Conference, 2003By means of simple examples, a design technique for multilevel secure databases is proposed. The design activity covers the conceptual modeling and design phase and consists of the development of secure data schemata and secure function schemata. Data schemata represent the semantics and secrecy properties of data while function schemata describe ...

Models of Multilevel Computer Security
1989Publisher Summary Some multilevel access-control models are surveyed in the chapter. This survey includes more recent models and also presents a few models in greater depth. The first access-control models were for operating systems, and modeled the policy by which an operating system grants requests by processes for access to controllable segments ...

A hookup theorem for multilevel security
IEEE Transactions on Software Engineering, 1990A security property for trusted multilevel systems, restrictiveness, is described. It restricts the inferences a user can make about sensitive information. This property is a hookup property, or composable, meaning that a collection of secure restrictive systems when hooked together form a secure restrictive composite system.

Security constraint processing in multilevel secure AMAC schemata
1992We describe the design environment AMAC which may be used as an aid for the construction of multilevel secure databases. The technique proposed consists of high-level data and security modeling using entity-relationship techniques, a decomposition approach for the construction of single level fragments from multilevel base relations, a supporting ...
