Along with many technological, environmental, and economic benefits, the rapidly moving connected world also represents an array of growing attacks like side-channel attacks, fault attacks, physical tampering, etc. Considering these risks, ensuring security and robustness of IoT becomes inevitable, in which IoT gateways play an important role.
IoT Gateways are undoubtedly the heroes of whole IoT paradigm, as they are the key piece of data collection in the connected system. In IoT ecosystem, security is the key aspect, in which, IoT gateway security is of prime importance since a secured gateway enables robustness of the entire IoT environment. If there are no sufficient security measures, there are chances of potential risks like malicious threats, spoofing, man-in-the-middle (MITM) attacks, data snooping, etc. If you lose a gateway in the middle of the communication chain, it will jeopardize the entire IoT ecosystem as gateway act as a gate or bridge between the edge devices and cloud.
