Abstract

Securing IoT (Internet of Things) systems in general, regardless of the communication technology used, has been the concern of many researchers and private companies. As for ZigBee security concerns, much research and many experiments have been conducted to better predict the nature of potential security threats. In this research we are addressing several ZigBee vulnerabilities by performing first hand experiments and attack simulations on ZigBee protocol. This will allow us to better understand the security issues surveyed and find ways to mitigate them. Based on the attack simulations performed and the survey conducted, we have developed a ZigBee IoT framework that could be used to solve security issues in the ZigBee protocol and in IoT in general. The system developed will: (1) predict a potential malicious attack by detecting the absence of a ZigBee node in the network and responding accordingly through a notification to the user of the system, (2) add another layer of encryption to the data transmitted between the ZigBee devices, (3) provide best practices for configuring and securing ZigBee devices and network, and (4) educate consumers about privacy and data security by involving them in the installation and giving them the autonomy to track in real time any motion activities detected around their house and inputting the time period that they would be notified should any suspicious activity occur.
