This paper presents a survey and an analysis of the current status and concerns of Internet of things (IoT) security.The IoT framework aspires to connect anyone with anything, anywhere.As opposed to the traditional Internet, in addition to humans, an IoT connects a large number of machines, resourceconstrained devices and sensors using heterogeneous wired and wireless networks.An IoT typically has a three conceptual layers consisting of Perception, Network, and Application layers.This paper describes security issues within and across these layers.Many security principles that should be enforced at each layer are also presented.Previous work specific to enforcing security for each IoT layer and corresponding countermeasures are also discussed.Finally, the paper presents future directions for securing the IoT. IoT ArchitectureIn an IoT architecture, each layer is defined by its functions and the devices that are used in the layer.There are different opinions regarding the number of
