As cyber attacks become more sophisticated and frequent, traditional security solutions are proving to be insufficient to protect against them. Moving Target Defense (MTD) is a promising approach that involves constantly changing the system's configuration, making it more difficult for attackers to exploit known vulnerabilities. By making the system dynamic and unpredictable, MTD can significantly improve its resilience to a range of cyber threats.In this thesis, we propose MTDIoT, a moving target defense solution designed specifically for IoT applications. IoT devices are often resource-constrained and may not have the processing power or memory to support complex security solutions. MTDIoT has minimal compute requirements and can be easily integrated with other security components, making it an ideal choice for IoT deployments.MTDIoT works by changing the network configuration dynamically over time or in response to specific events. This makes it harder for attackers to identify and target specific devices and services. Additionally, MTDIoT has the ability to exclude compromised nodes from updated network configurations, isolating them from the rest of the network.We evaluate the performance of MTDIoT in a simulated network environment. Our results demonstrate the effectiveness of MTDIoT in reducing the success rate of attacks on IoT applications. By constantly changing the network configuration, MTDIoT makes it more difficult for attackers to identify and exploit vulnerabilities, reducing the overall risk of cyber attacks.MTD has the potential to improve the security of a wide range of systems and applications, including cloud computing, critical infrastructure and networks. While MTD may not provide a complete solution to all cyber threats, it can significantly enhance the resilience of systems and reduce the attack surface available to attackers. As such, MTD is likely to become an increasingly important component of modern cybersecurity strategies.
