BASIC ASPECTS OF CONFIDENTIAL INFORMATION SECURITY IN CRITICAL INFORMATION INFRASTRUCTURE OBJECTS

Abstract

The rapid development of information and communication technologies has increased the vulnerabilities of various networks, systems and objects as well as made it much more difficult to ensure their reliable protection and security. All these factors have led to the fact that the world's leading countries have begun to pay considerable attention to cybersecurity and critical information infrastructure protection. However, the protection of various types of information with restricted access (in particular, confidential information) at critical infrastructure objects remains unexplored. With this in mind, the paper analyzes the existing approaches of the world's leading countries to the confidential information protection at critical infrastructure. The analysis revealed that today there are no comprehensive, multifunctional methods of protecting confidential information at critical information infrastructure. In addition, the classification of critical information infrastructure objects according to information security requirements is developed. This classification by determining the type of processing information, possible access modes and criticality category, allows to ensure unity of approaches to protection of these objects belonging to different types, including information systems, automated control systems and information-telecommunication networks.
