Cognitive Radio (CR) is a technology that promises to solve the spectrum shortage problem by allowing secondary users to coexist with primary user without causing any interference to the communication. It aims to improve the utilization of the radio spectrum. Although the operational aspects of CR are being explored widely, its security aspects have gained little attention. In this survey, we present a comprehensive list of major known security threats and attacks within a Cognitive Radio Network (CRN). Our objective in this paper is to analyze the security issues of the main recent developments (which includes attacks and mitigations) of Cognitive Radio Networks. We hope that this survey paper can provide the insight and the roadmap for future research efforts in the emerging field of CRN security and utility.
