Visalert is a visualization system designed to increase the monitoring and correlation capabilities of computer network analysts engaged in intrusion detection and prevention. VisAlert facilitates and promotes situational awareness in complex network environments by providing the user with a holistic view of network security to aid in the detection of sophisticated and malicious activities, and ability to zoom in-out information of interest. The system provides a mechanism to access data from multiple databases, and to correlate who, what, when and where. This chapter describes the design process that enabled the team to go from the conception of rough visual sketches to the implementation and deployment of a finished software. In addition, the chapter describes the issues that the interdisciplinary team had to address to carry the project from idea to product.
