Architecture of the system with a subsystem of providing fault tolerance, survivability and information protection of specialized information technology

The construction of a model of a typical architecture of information technology for the construction of specialized information systems intended for the automation of information processing processes, management processes and decision-making processes based on a spatially distributed multi-machine system that provides a high level of fault tolerance, survivability and information protection is considered. The classification and structure of the information system, which has a multi-level organization of interacting hardware and software tools, as well as the features of such an organization when building a subsystem to ensure fault tolerance, survivability and protection of information in a distributed information system of specialized application, are given. Methods of implementation of mechanisms for ensuring fault resistance, survivability and protection of information are considered and classified, with their presentation in a general model of a specialized information system. It is shown that the most urgent problem of the construction of the considered systems is the creation of a method that is a general approach to the construction of highly adaptive systems with increased fault tolerance, survivability and protection of the information processed in them. A key aspect, according to the generalized method, is the creation of a system architecture that can adapt to the requirements of a specific specialized IS. The IS architecture development process itself will include the implementation of two stages. This approach to the development of IS made it possible to ensure the implementation of such general requirements for the construction of systems as systematicity, openness, compatibility, unification and efficiency. As a result, an IS architecture was obtained in which a rational ratio between costs and target effects was achieved.
