Delve into the architecture of defensive strategies to protect IoT devices from targeted attacks

The great development in information technology and the Internet of Things is accompanied by several concerns, the most important of which are security vulnerabilities and cyber-attacks that affect the joints of the connection between resources, as old methods are no longer sufficient to reduce security vulnerabilities and protect interconnected systems. The study aimed to design a strategy that works on defense, combating deception, controlling operating systems, and diversity in the process of operational mobility with a process of updating and evaluating in real time by deploying deceptive nodes and dynamically moving between operating systems of Internet of Things devices and continuously monitoring the attack surface. This study focuses on the security returns resulting from the designed system, as it adopts a multi-layered security approach to protect Internet of Things networks from complex and targeted threats. This defensive approach is a powerful approach to increase the complexity of attackers and try to stop them and improve the overall resilience of the Internet of Things ecosystem. The effectiveness of the proposed defense-in-depth strategy is evaluated through simulation and performance analysis, which indicates its ability to mitigate various types of attacks while maintaining acceptable overhead.
