As the Internet of Things is widely utilized, there may be a chance of attacks in the security of various types of Internet of Things devices. To secure the devices from these assailments, some countermeasures must be taken. These countermeasures are utilized which avails the Internet of Things devices to be more secured to maintain their privacy and amends the security of the system. In this paper, we endeavor to highlight IoT security and privacy contravention through ostensibly with different angles. This paper represents the overview of Security Principles, Security Threats and Security challenges at the application layer and its countermeasures to surmount those challenges. We mainly focused on the various threats on the security of IoT devices and furthermore we have also discussed its precautions.
