This course is the second course in computer operating systems, building on the material introduced in CS481. The focus area for this course is Information Assurance. Topics covered include operating systems, information assurance, system and network security, and offensive and defensive information operations. A course project and term paper brings together the diverse concepts learned in CS481/CS482. In a culminating exercise, cadets participate in an inter-service academy competition in which they develop and implement defensive measures to protect a production network from intrusions.
