Mechanism for ensuring the reliability of information system objects

It is difficult to imagine the functioning of modern society without information systems of various levels of complexity. Quality control of the functioning of systems is one of the main tasks that should be paid close attention to. One of the criteria for the quality of an information system is reliability, the better the systemis, the more reliable it is, and viceversa. In this regard, the purpose of the study is to choose the most appropriate mechanism for ensuring the reliability of information systems. This article discusses the main mechanisms for ensuring the reliability of informationsystemobjects such as: error prevention, error detection, error correction, error tolerance; highlighted criteria for their evaluation such as: the ability to restore the initial state of the system, the ability to perform redundancy, fault tolerance, testing, complexity of implementation, the ability to eliminate errors at the stage of system design. The factors determining the occurrence of threats to the objects of information systems and security threats are analyzed. A comparative analysis of the mechanisms for ensuring the reliability of information system objects according to the selected criteria and analyzed factors is carried out. The formalized model, architecture and interface of the software are presented. A series of experimental studies has been carried out
