Digital boom brought empowerment to seamless connectivity by enabling manufacturers to harness the power of the Internet into their products, opening up the world of the Internet of Things (IoT). However, such connectivity has also brought the side effect of such power being abused by the bad actors, who scan open ports for services and then make their way in by exploiting vulnerabilities in the system. There is an increasing need to enable IoT devices to be fully patched and secured. This paper studies a unique but practical method of security called "Port Knocking." Our experimental results on a resource-constraint IoT gateway show that port knocking not only secures the device and provides a secure remote management option, but also makes power consumption lower. The results obtained make it an effective security layer for securing IoT devices.
