As the use of low-power and low-resource embedded devices continues to increase dramatically with the introduction of new Internet of Things (IoT) devices, security techniques are necessary which are compatible with these devices. This research advances the knowledge in the area of cybersecurity for the IoT through the exploration of a moving target defense to apply for limiting the time attackers may conduct reconnaissance on embedded systems while considering the challenges presented from IoT devices such as resource and performance constraints. We introduce the design and optimizations for µMT6D, a Micro-Moving Target IPv6 Defense, including a description of the modes of operation and use of lightweight hash algorithms. Through simulations and experiments µMT6D is shown to be viable for use on low power and low resource embedded devices in terms of footprint, power consumption, and energy consumption increases in comparison to the given security benefits. Finally, this provides information on other future considerations and possible avenues of further experimentation and research. / Doctor of Philosophy / This research aims to advance knowledge in the area of cybersecurity for the Internet of Things through the exploration and validation of a moving target defense to apply for limiting the time attackers may conduct reconnaissance on low powered embedded system devices considering the challenges presented from IoT devices such as resource and performance constraints. When an attack is carried out against a network, reconnaissance is utilized to identify the target machine or device. Limiting the time for reconnaissance, therefore has a direct impact on the ability of an adversary to carry out an attack. Many of the security techniques utilized today do not fit the IoT constraints. Research in this area is just beginning and security is often not considered. Sensors collecting and sending information can be compromised both through the network and access to the physical devices. How can these devices securely send information? How can these devices withstand attacks aiming to stop their functionality or to gain information? There are many aspects which need to be investigated to understand security vulnerabilities and potential defenses. As our technologies evolve our security defenses need to evolve as well. My research aims to further the understanding of the security of the IoT devices which have quickly become pervasive in our society. This research will expand the knowledge of the ability to safe guard connected devices from cyber-attacks and provide insight into the space and performance requirements of a technique previously only used on large scale systems. By designing, implementing experimental prototypes, and conducting simulations and experiments this research assesses the viable use of a Micro Moving Target IPv6 Defense (µMT6D).
