Introduces readers to the field of cyber modeling and simulation and examines current developments in the US and internationally. This book provides an overview of cyber modeling and simulation (M&S) developments. Using scenarios, courses of action (COAs), and current M&S and simulation environments, the author presents the overall information assurance process, incorporating the people, policies, processes, and technologies currently available in the field. The author ties up the various threads that currently compose cyber M&S into a coherent view of what is measurable, simulative, and usable in order to evaluate systems for assured operation. The issue of cyber security, somewhat slow to be recognized during information technology’s rapid rate of development and dissemination into business enterprises over the last half century, often gets the same level of news coverage as natural disasters or stock market anomalies.
