Web-based Visual-Interactive Exploration of Network Data

The amount of cyberattacks in Germany increased over the last years but many small and medium-sized enterprises can not afford Security Operation Centers (SOCs) to find and handle these attacks. In this work I created a visual interactive analysis tool as a web-application that is used to show different aspects of data with interactive visualizations to enable users to find irregular traffic and attacks. Since the amount of data can be enormous the main visualization shows the data in an aggregated form. To appeal to both experts and novices in network traffic I created two different single page interfaces with different visualizations and layouts that best suit their abilities. To find out if the interfaces fit their expected audiences best I conducted a user study where users had to complete tasks in both interfaces and tell which interface is better for experts or novices.
