Knowledge-assisted visualization is a concept in information visualization that incorporates the knowledge conversion processes into the design, implementation and the utilization of visualization tools. Knowledge conversion processes describe the exchange of knowledge between humans and machines in the form of externalization, internalization, collaboration, and combination. In this paper, we bring those concepts to the cyber security visualization domain. We draw from state of the art research works in knowledge-assisted visualization to derive a method for identifying the concepts. We then analyze VizSec{IEEE Symposium on Visualization for Cyber Security papers and present the lay of the land of knowledge conversion in ten years of research in VizSec.
