Abstract: In the conditions of growing challenges in cyberspace, the information environment protection system is a preventive mechanism of protection against real and potential risks and threats to national interests. The study analyzed the position of Ukraine in the world rankings for cyber security and outlined promising directions for increasing its level, one of which is the improvement of information protection systems of critical infrastructure objects. A system of protection of the information environment against cyber attacks using of the modular number system based on non-positional code structures is proposed. Of the various options for the practice of intrusion detection and prevention systems, this chapter discusses the data comparison algorithm, which consists in continuously monitoring and scanning data by constantly comparing data with user and service information patterns, as well as threat patterns and indicators based on previous experience, not only own, within the local network or system, but also on a global scale. The chapter presents an improved method of fast comparison, which allows to carry out the comparison procedure in the modular number system, both in positive and negative numerical ranges. Improving the method of fast comparison of two integers is carried out by increasing the accuracy of comparison, by representing numbers in an artificial form, which expands the area of effective use of computer systems for processing integer economic data in the modular number system. The use of an improved method for fast comparison of data in the modular number system for one-byte, two-byte, three-byte, four-byte and eight-byte numerical bit grids of the computer systems, respectively, by 16 %, 37 %, 50 %. It is 58 % and 72 % more efficient in terms of number comparison time than using the fastest of the existing number comparison methods in the modular number system, which is based on the principle of nulling. The proposed method provides maximum comparison accuracy with a minimum amount of equipment for comparing devices. This circumstance makes it possible to obtain a reliable result of the data control operation. Its use makes it possible to identify potential cyber threats and take preventive measures, which will increase the level of protection of critical infrastructure objects.
