The analysis of threats of the information of systems of the electronic document circulation

The analysis of system of electronic document circulation (SEC) and the making automated components is carried out. The general model of system in which technical components and communication channels, and as the standard protection frames of the information most used for today are described, is constructed. All system has been broken into two sectors external and internal on which the weakest places of system have been revealed. The analysis of threats has been spent on three broken properties of safety: threat of confidentiality, integrity and availability. In the analysis of threats of confidentiality — the basic ways of reception unapproved access (UA) to system SEC, for the purpose of plunder by the malefactor of the confidential information have been described. The analysis of threats of integrity gives the chance to define degree value of separate links of system, and also a consequence from their crash. The analysis of threats of availability lets know about availability of separate components SEC which can lead to errors and various failures in system that creates a basis for construction of mechanisms UA.
