The course objective is to provide hands-on laboratory exploration of adversarial cyber threats to DoW networks and weapon systems. Students learn and, in the lab environment, execute basic offensive cyber techniques, develop system requirements to defeat the threats, implement countermeasures, and assess countermeasures effectiveness. Two days are spent on enterprise network attacks and security countermeasures, and one day is spent working with an unmanned aerial system simulator, which is representative of currently fielded DoW unmanned weapon systems. The inclusion of offensive techniques training for DoW weapon systems differentiates this course from similar training provided in the commercial sector.
