What are the roles of electronic and Cyber Warfare in cognitive radio security?

Traditionally, Electronic Warfare (EW) and Cyber Warfare (CW) have been viewed as independent, disparate disciplines. However, they are often trying to accomplish similar tasks, and thus may be viewed as two sides of the same coin. When both the attacher and defender employ cognitive techniques, the edge may go to the side that integrates techniques from both EW and CW. In this paper, we examine two case studies in radio security. We examine what happens when the attacker is cognitive, and consider cognitive EW/CW approaches to defend against the attacks.
