As more number of devices are connected to internet day by day, directly or indirectly for different needs like monitoring, management, automation and so on. Number of devices connected to internet is more than the number of people connected to it. Among the devices that are connected to the internet, most of the devices are used for communication and collection of data in real time. Providing security for devices over the internet is becoming challenging task since data processing is in real time. In this paper, we introduce a new cost effective framework using a private Certificate Authority (CA) to detect these rogue devices trying to connect to the web server and then to prevent them from connecting to the web server. We use MAC address with certificates for authenticating a device. Our proposed security framework improves the security by detecting and preventing the rouge devices in Internet of Things (IoT). Most number of attacks are reduced by identifying and restricting the rouge devices in the network.
