Securing Internet of Things Networks with Gateways and Multi-SSID Technology
(Institute of Electrical and Electronics Engineers Inc., 2021) Kaşif, Ahmet; Toğay, Cengiz; Levi, Albert
The Internet of Things (IoT) technology has entered our lives with industry and smart home technologies, and today it has started to be used in fields such as health, finance, transportation, energy and space research. Existing security solutions for IoT devices with limited hardware capacity do not provide integrated protection. In this study, it is aimed to increase the security of the IoT devices in the local network and the confidentiality of the data produced within the system by supporting the multiple SSID feature of the routers with the controller application placed on the gateway. Wireless communication security and packet transmission performance at the physical, network and application layers of the proposed architecture have been tested in real world conditions. Another contribution of the presented study is to limit the communication of devices with other devices in their own networks and with the external network in the light of the information defined by the manufacturer on a device basis. The results show that the proposed system offers a secure and performance efficient solution for protecting IoT environments in the local network.
