Modeling the process of selecting the optimal method for monitoring the integrity of information in an automated system taking into account the specifics of its operation

the paper analyzes the existing basic methods of data integrity control, suggests criteria for their effectiveness and a model for choosing the optimal method for implementing data integrity control procedures, taking into account the specifics of the functioning of an automated system. The applicability of the proposed model for choosing the optimal integrity control method for a specific system is evaluated. It is emphasized that ensuring the integrity of information in modern automated systems is becoming one of the most critical tasks, the solution of which directly affects the functions related to maintaining the reliability of the information system and data security. The high dynamics of the increase in the volume of processed data of various structures, the increasing complexity of the infrastructure of the supporting part of the information system and the increasing equipment of intruders make the problem of integrity control relevant. The current methods of solving this problem, including checksum mechanisms, electronic signatures, and hierarchical integrity control methods, are effective, but they face limitations related to limited resources, complexity in implementation in automated systems, and vulnerability to modern types of attacks. The following description is intended to determine the optimal method of information integrity control, to build its model, taking into account the specifics of the functioning of the automated system
