Organization of Data Access Based on Binary Rules in an Intelligent Testing System

Abstract

In this paper, we consider one of the levels of information security, namely the data access control model, which implements the principle of the system of delineation of rights based on binary rules. Nowadays the relevance of this topic is justified because of need to restrict access to data in any virtually system where there is any organizational structure among users. The purpose of this work is to improve the security of stored data by limiting access to it. The principle of the system is that each user has a right or set of rights that determine the level of access to information for the user. The set of rights is represented in the form of a binary number, where the length of the number is determined by the number of all possible rights. To test this approach for delineation of rights, an intelligent testing system (ITS) was used, in which this approach is presented as one of the ITS modules. The final result of this work is the implementation of the algorithm for providing access to data based on binary rules, which will help to increase the level of security of the system, in which this algorithm will be applied. The presented material will be useful for information security specialists.
