DEVELOPMENT OF SECURE CONTAINERIZED APPLICATIONS WITH A MICROSERVICES ARCHITECTURE

Abstract

The article analyzes approaches to software development that allow creating complex container applications with a microservice architecture based on automation tools and flexible development methods. The development of cloud technologies, the global strategy of containerization, the modernization of the application architecture, and the increase in security requirements have led to a change in the application development methodology. The study aims to determine approaches to increase the speed of development, security and quality of software code of containerized applications by implementing security principles and automation tools at all stages of the life cycle. Features and development prospects of microservice applications deployed in a container environment are considered. The advantages of the container infrastructure are defined: mobility, scalability, an additional level of microservice security. Containers provide an isolated environment for running a microservices, this reduces the risk of security vulnerabilities and simplifies interaction between microservices. The article identifies the security problems of microservice applications and the main vulnerabilities associated with the use of containers. It is determined that DevSecOps methodology allows implementing modern practice of continuous integration, continuous delivery, continuous application deployment and integration of security tools at all life cycle stages. DevSecOps describes development processes, deployment and operation processes using Security as Code and Infrastructure as Code practices. The research describes the model for developing and deploying   microservice applications with containerization, defines the security domains, and the security controls for DevSecOps development pipeline. Based on this model, the main security control tools that must be used at all development and deployment pipeline stages are defined. The article proves that the considered technique regulates the implementation of given security procedures at all stages of the pipeline, allows to reduce development time and improve code quality for container applications with a microservices architecture.
