In this paper, we propose a visualization-based policy analysis framework that enables system administrators to query and visualize security policies and to easily identify the policy violations, especially focused on SELinux. Furthermore, we propose a visual query language for expressing policy queries in a visual form. Our framework provides an intuitive cognitive sense about the policy, policy queries and policy violations. We also describe our implementation of a visualization-based policy analysis tool that supports the functionalities discussed in our framework. In addition, we discuss our study on usability of our tool with evaluation criteria and experimental results.
