Monitoring volumes of malicious network data for across multiple sources can potentially be overwhelming. As a result, vital data is at a greater risk of being overlooked and the time span for analyzing it could be too lengthy. One way to address this issue is to employ network security visualization techniques to evaluate security risks and identify malicious activity to help mitigate compromised nodes on a network. The purpose of this thesis is to introduce a visualization framework to help reduce task-completion time, enhance situational awareness, and decrease user error of complex visualizations for network security applications. From the developed framework, three techniques are suggested as contributions using visualization and interaction: (1) Stereoscopic visualization technique aims to increase user awareness of vulnerabilities and malicious attacks, (2) the recommender system aims to ensure efficient navigation in complex 3D environments, and (3) an interaction system aims to assist in usability of visualization environments using Natural User Interfaces (NUIs). To investigate the aforementioned techniques, the following tools were created: 3D Stereoscopic Vulnerability Assessment Tool (3DSVAT), Parallel 3D Coordinate Visualization (P3D), NAVSEC recommender system, and Interaction System for Network Security (InterSec).
