INFORMATION PROTECTION, REFRACTORING, CORPORATE DATABASES, MATHEMATICAL MODEL, EXPERT MODELING SYSTEM The object of research is computerized systems of food and processing industry. The purpose of the work is to improve the means of protection of storage and database management systems, study the refractoring process in different methodologies, its features of use, and provide recommendations for choosing development methodologies for different projects, improve management methods by creating specialized decision support methods for operational production planning. products, creation of a mathematical model for the development of new types of food concentrates using coextrusion technology and a mathematical model for calculating the technological process of saturation, as well as improving methods of developing ice cream recipes by creating and using expert modeling system. Research methods - software updates without signature verification or from unverified sources is a type of attack in which malicious updates are downloaded independently. The main protection against this type of attack is qualified database administrators, but they can not provide complete security. One of the radical methods to improve the filtration and sedimentation properties of sludge is pre-saturation treatment. With the help of the CASE tool Erwin Process Modeler and the methodology according to the IDEF0 standard, the production of ice cream by building a structural and functional model was investigated, which allowed to identify the main business processes and information flows that provide them. As a result of modeling and analysis, it was found that the main bottleneck in the manufacture of ice cream is the business process "Make an operational recipe."
