Measures to ensure the reliability of the functioning of information systems in respect to state and critically important information systems

This article is devoted to the development of measures, such as organizational, technical and legal measures, to ensure the reliability of the functioning of information systems in respect to governmental and critically important information systems. The article talks about measures and recommendations to ensure the reliability of Information Systems in relation to Public Information Systems; measures to Ensure the reliability of Information Systems in relation to Critical Information Systems, main criteria for classifying information and communication infrastructure objects as critical information and communication infrastructure objects, critical sectors, their subsectors and critical services, questionnaires for the evaluation of infrastructure providing critical services, criteria for assessing the criticality of services, differences between standard information system (IS) and critical information system; looks at one of the possible options for the process of sustainable operation of critical information system. The application of the proposed methods and approaches will increase the level of reliability of information systems, to ensure the timely identification and elimination of relevant risks. Ensuring the reliability of information systems in relation to public information systems envolves things such as: organizing control over the activity planning aimed at reliable and safe functioning of state information system; implementing processes to ensure the reliability, fault tolerance and security of information systems; formation of regulatory requirements to ensure the reliability of public information system; monitoring the continuous training and certification of employees working with information system; raising awareness of employees and management responsible for the performance of public information systems on the most relevant threats, vulnerabilities, risks and incidents related to the reliability and security of information system; conducting regular audit and assessment of the level of ensuring the reliability of state information system; carrying out preventive measures to eliminate incidents and reduce the risk of information system failures; connecting the telecommunications network to a single gateway to the Internet; connecting the state information system to the information security event monitoring system and transmission of operational information on threats and incidents to the national Information Security coordination center.
