In article the system of the analysis of the software regarding lack of not declared opportunities is considered. Such system is intended for protection of information resources of workstations and servers, their components, programs or data against unauthorized activity. It can be used for the analysis of a source code of the software, including, for example when carrying out certified tests of the software for lack of not declared opportunities. The existing systems of the analysis of the software possess a number of shortcomings which do not allow to compare results of researches with a control copy (version) of the same software. This circumstance leads to high time expenditure (at the expense of a full cycle of verifications of files of source texts of various versions of the software), and also to decrease in trust to results of researches. Thus, there is a need to develop the system of the analysis of the software regarding lack of not declared opportunities, the reliability of results of the analysis of the software providing increase by fixing of an initial state, check of redundancy of source texts and the analysis of contextual information in source texts of the studied software.
