The imperative factors are elucidated, characterized the circumstances and environments of current and future economic information and informatics systems, which objectively contributed to the urgent need for invention, elaboration and using of various means and methods of protection of information resources. The functional value of the field in question in the market economy environment and in integrated informatics systems is emphasized. The content of the material is structured and rendered from the positions of the unitary process of economic management, which performs not only information, but also and the materials activities, in interconnection and direct interaction in real time. Its subdivisions are also specified and in this basis - determined the field of application of the above-mentioned means and methods in the existing conditions of processing the informational values of economic content. In this context, the subdivisions of the previously nominated process, its constituents, are systematized and analyzed. The general scheme of the interconnection and interaction between the parameters of protection and efficiency of the functioning of economic integrated informatics systems is established and elaborated. Depending on the application environments, the categories of protection of information units, physically made in the form of data elements, on manual and informatics storage media are highlighted. At the same time, in terms of mutual influence with information resources, some aspects of the protection of other informatics resources are elucidated. Tangentially, the terminology is examined and the concordance of the means and methods of organizing and carrying the data protection processes is performed. The problems of this department of economic informatics and the possible ways to solve them are formulated.
