Docker containers allow developers to package their applications and operating environments into an image

and allowing them to run quickly on any physical machine or virtual machine. With fast start-up speeds and high resource utilization

Docker containers have developed very rapidly in recently. Since the security of containers depends entirely on the underlying operating system

there are still great doubts about the security of containers. Based on the analysis of the security risks of Docker containers

this paper puts forward the corresponding technical requirements for security protection

and looks forward to the following research direction.
