Smart society with convergences of technology and production comes, innovations of technology and production are expected to prevail everywhere. Also, a modern society is in a age of 'Internet of Things(IOT) and ‘Internet of Everything(IOE)’, which exchanges information among objects, via Internet, and it is expectable that the field of Internet of Things(IOT) will become a new-growth engine industry. However, as the interconnections among things are expanded, security threats are expected to be increased highly. Also, as the number of devices that require security increases and as the devices are enlarging their field to lightweight, low-power, hyper-connected and etc, the device-security technologies customized for each of the devices are needed in this stage. In this paper, I consider to Security Threat three part of Industry fields, Devices, Network and Flatform/Service. Therefore, by analyzing the security requirements for Internet of Things(IOT) in this thesis, the analysis is expected to be utilized for the countermeasures against security threats that can attack Internet of Things(IOT) in future. And as the expanded to Internet of Everything(IOE), the new security threat to security requirements that can respond to the threat analysis and developing technology are constantly will made to future.
