Summary on network security visual analysis

Visual analysis on network security is a new area, it consists methods and technology of visualization and network security analysis, which has new challenges. Researchers on network security visualization have done certain extent research and accumulated much. Especially with the rapid development of visual analysis, visual network security analysis achieved rich results in recent years. However, there is less study on basic research framework and principle of security visualization analysis, this dissertation summarizes concerned problems in the field of security analysis, data sources, visual analysis techniques and related overview of visual analysis system. Through analysis of these systems, network security visualization on the research questions can be tested and directions for future research can be provided.
