Analysis of information security of distributed information systems

The paper presents technologies of analysis, synthesis and correction of information security architectures in distributed information systems. We consider different fragments of information security subsystems and models in the form of diagrams as identical. Then the basic construction elements of an information security subsystem in a distributed information system are diagrams of information security. Their advantages in comparison with traditional approaches are that these basic construction elements comprise an integrated approach to realization of security system. It allows to carry out hierarchical decomposition of a subsystem of information security. Then secure interactions between secure isolated domains are constructed.
