Modern directions of foreign research in the field of system dependability

Abstract

Abstract. This article analyzes modern trends of the development of the theory and practice of dependability of computer and other systems. The use of dependable computer systems and the development of methods for dependability indicators calculation are discussed at specialized national and international forums and conferences in many countries around the world. It is still relevant to define, clarify and formulate the basic concepts and taxonomy of the dependability theory. All over the world intensive scientific research, practical scientific and technical development of computer systems and networks are carried out with the aim of ensuring dependability in aviation, rocket, space and military-industrial complexes, control systems at nuclear power plants, railway transport, healthcare systems and also in the financial sphere of business-critical application. Dependability theory is relevant, but still underdeveloped in the following areas: cybersecurity systems, network traffic anomalies detection, computer-aided design systems, augmented and virtual reality systems, self-healing systems, robotics, cyber-physical sensor systems, methods and means of human identification (biometrics), environmental monitoring, large-scale data analytics and data mining for business areas and digital banking, databases, healthcare computer systems, wireless communication systems. The following areas are still gaining relevance towards improving their dependability level: cloud storage and computing, encryption, quantum computing and cryptographic methods, maintaining confidentiality and personal data access control, blockchain security and reliability. The results obtained in the paper can be useful for a wide range of experts that are involved in the research of dependability in all areas of its application.
