The Swedish Defence Research Agency (FOI) simulates cyber attacks for research and education purposes in their cyber range, CRATE, with a system called SVED. This thesis describes the process of creating a visualization of the log files produced by SVED, with the purpose of increasing the users’ comprehension of the log files and thereby increasing their knowledge of the simulated attacks. To create an effective visualization a user study was held to know the users’ needs, experiences and requirements. Several designs were created based on the results and one was selected and refined using feedback from workshops. A web-based implementation of the design was created using the D3.js library, which included a directed graph, icicle chart and network graph to visualize the data. Thereafter an evaluation was held to analyze if the implementation was more effective than the log files, by letting the participants solve tasks defined by the user study. The results from the evaluation indicates that the visualization has a higher success rate than the log files when solving the tasks. They also indicate that finding the solution requires less time with the visualization. However, since the evaluation tasks were based on the user study, the results only conclude that the visualization is more effective when solving similar tasks. For further development the visualization could be improved with features like real time rendering and linkage with FOI’s internal systems. Additionally, with more research and further testing, the visualization could be used as a tool for standardization of graphics in cyber space. In conclusion, a visualization of the log files has been implemented and according to the evaluation does the visualization increase the users’ comprehension of the data in SVED’s log files.
