Military Message Systems: Requirements and Security Model.
Abstract
Military systems that process classified information must operate in a secure manner, i.e., they must adequately protect information against unauthorized disclosure, modification, and withholding. A goal of current research in computer security is to facilitate the construction of multilevel secure systems, i.e., systems that protect information of different classifications from users with different clearances. Security models are used to define the concept of security embodied by a computer system. A single model, called the Bell and LaPadula model, has dominated recent efforts to build secure systems but has some deficiencies. We are developing a new approach to defining security models based on the idea that a security model should be derived from a specific application. To evaluate our approach, we are formulating a security model for a family of military message systems. This paper introduces the message system application, summarizes our approach to developing a family of secure message systems, presents our security model, and summarizes our plans. (Author)
