Abstract (in Japanese) (See Japanese page) 
(in English) Decentralized Information Flow Control(DIFC) is a method to prevent vulnerabilities more effectively than Mandatory Access Control(MAC) by allowing application developers to set policies.
However, the implementation of DIFC using existing methods requires modifications to the operating system, which creates a high barrier to implementation. As a method that does not require any modification to the OS, we proposed a method of implementing the DIFC system on a Container-based virtualization environment.
In this study, we implemented this method on a Container-based virtualization environment and evaluated it by running a practical web application on the system. The results of the security evaluation showed that the method can prevent vulnerabilities of a practical web application. In addition, the performance evaluation showed that the overhead was about 33% compared to the existing container environment, and there was less impact than existing methods.
