IOT Security Challenges and Issues: An Overview

Now a days physical environment are changed by the wireless sensor network. The wireless sensor network consists of number of tiny sensor nodes for sensing the environment with the limited computation and communication capabilities. The Internet of Things enabled by Wireless Sensor Networks (WSN) and RFID sensors finds a number of applications in almost all the fields such as health, education, transportation and agriculture. This paper briefs the idea of Internet of Things (IoT) and the security challenges to its future growth IndexTerms Wireless Sensor Network, (WSN), Internet of Things(IoT), RFID.
