Formal model of process functioning in the operating system

The article presents a formal model of the functioning of the process in the operating system, created on the basis of a subject-object approach to the separation of the main elements of the operating system. A feature of the presented model is a high-level abstraction of the interaction between the operating system processes and resources, which allows applying the obtained results to a wide range of similar systems. The use of this model is necessary for carrying out the transition from the real world object (process) to a formal model to take into account the significant properties of the behavior of the process both during the static analysis phase of a binary executable file and the dynamic phase of monitoring its implementation. The system of safe execution of code is an extension of the composition of such approaches to the detection of malicious software as the application of the formal verification method «Model checking» and the use of machine safety to monitor the implementation of the studied program. This system allows using in corporate information and computer networks only such software, reliability of which is confirmed by a formal mathematical proof and continuous monitoring of its execution.
