Basic IT elements have been emphasized and characterized from the point of view of controlling its current level of usefulness (reliability and security). A model of engineering infrastructure was proposed for maintaining the required level of usefulness. Desired current IT usefulness is obtained by generating appropriate functional and IT security configurations from a set of allowable solutions. The proposed concept of ensuring reliability and security, taking into consideration the impact of not only various types of risk factors, but also changes in the conditions of the working/operating environment of both IT, its basic domain systems, and the information system, is the authors' own proposition.
