This paper aims to assess the usefulness of 3D interactive interfaces to display periodic signals in a network. Past research has shown that data visualization simplifies alert classification drawn by periodicity-based Intrusion Detection Systems. However, 2D visualizations have limitations such as screen space availability. This is why we created CyberCopter, a prototype that uses a 3D helical representation to highlight periodic patterns in a dataset. We tested CyberCopter usability and efficiency in a fraud detection scenario. It scored 77 on the SUS questionnaire which demonstrates acceptable usability.
