Segmentation of information-technology infrastructure of situational center by the loop security attribute

Situational center is shown as the key system of critical important objects of information-technology (IT) infrastructure. Based on this, the article formulates the principal terms that should be used for solution of the situational centers information security problem. It is justified that creation and management of information resources are part of the basic functions of IT-infrastructure of situational center. In this sense, a situational center is regarded as an accumulative information system with different information sources and forms of its information presentation. It is shown that allocation of processing circuits by security classification is one of the simplest ways to make a primary data input nonconflict in the perimeter of a situational center for their further safe processing. The authors propose an implementation of the architecture where certified superimposed and embedded data protection facilities are used to provide the information security.
