6 Conclusion
Docker is a lightweight virtualization method that packages applications and operating environments into container images, allowing applications to run independently directly in the container. Due to its lightweight, high efficiency and easy deployment characteristics, Docker has been widely used in cloud computing and microservice architecture.
According to statistics from the National Security Vulnerability Database, since Docker was officially released in 2013, as of August 2022, a total of 124 related vulnerabilities have been discovered, of which 71% are high-risk or higher vulnerabilities, which has had an adverse impact on application ecological security and user confidence. . Therefore, the security of Docker has received widespread attention from industry and academia, and many research ideas and methods have been continuously proposed. This article compares and analyzes Docker security-related research ideas, methods and tools, and points out possible future research directions.
