Abstract--- In recent years, the resulting of "cognitive" concept, a new field called “Cognitive Wireless Sensor Networks ” is gained to literature. The traditional Wireless Sensor networks are already complicated and complex security, adding cognitive turned into more complicated and more complex. The purpose of the paper to investigate security vulnerabilities in cognitive sensor networks, and propose methods of defense against these vulnerabilities to maximize the security of sensitive information circulating in a network
