With the rapid development and fast increasing use of Internet of Things (IoT) in day to day life, more devices are connected to Internet. In the smart home, smart wear, smart manufacturing, and smart health care and everyday life, IoT devices are commonly used. Therefor security vulnerabilities are increased endlessly. As more devices are connected to internet, increasing continuously huge amount of data and most of data are available publicly which means that we can access data from anywhere, anytime or by any user from Internet. Managing security of these devices are difficult task for security analyst. For security of devices OSINT on devices is requires. Open Source Intelligence (OSINT) is type of intelligence gathering from target which are publicly available. There are many OSINT tool available like Maltego, Shodan, and Censys for devices and network monitoring. In this paper, an inclusive survey of OSINT, types of OSINT tools and comparison of tools are described. The merits and demerits of each OSINT tool are presented. At last summarize conclusion and future work.
