Attack surface model for complex systems based on microservice architecture

Purpose of research . Increasing the level of security of information processed in information systems based on microservice architecture; by creating an effective protection system designed on the basis of knowledge obtained as a result of creating an attack surface model. Methods. During the analysis, types of information systems (IS) were considered, among them complex IS created on the basis of microservice architecture were highlighted. Russian and foreign technologies, software allowing to automate the process of information processing were considered. A set-theoretic model of constructing an attack surface for information systems built on the basis of microservice architecture was proposed. Results. An original approach to the description of the attack vector and surface is proposed, including a list of frequently encountered vulnerabilities, methods and tools for implementing an attack, as well as a list of possible objects of influence. A set-theoretic model for constructing an attack surface for information systems built on the basis of a microservice architecture is developed. Results. Conducting research and developing an attack surface model for complex information systems built on a microservice architecture will improve the level of knowledge in the field of information security (IS) and ensure the security of processed data by building an effective information security system that takes into account current threats and methods of influencing the information system.
