Agricultural IoT PDRR scheme based on an improved cyber kill chain
Rikun Huang, Rong Ma, Hao Zhang · 2024
As the application of Internet of Things (IoT) technology in agriculture deepens, the lack of security in agricultural IoT systems has become one of the main bottlenecks restricting the development of agricultural IoT. To address the data and system security issues of agricultural IoT, this paper proposes an agricultural IoT PDRR scheme based on an improved cyber kill chain. By understanding the lifecycle of network attacks through the improved four-step cyber kill chain model, and utilizing the synergistic effects of honeypot and firewall technologies, a defense system capable of adapting to attacker behaviors and effectively disrupting the cyber kill chain is constructed. The PDRR is achieved by combining proactive and passive defense methods. Experimental results show that the agricultural IoT PDRR scheme based on the improved cyber kill chain proposed in this paper can effectively interfere with and disrupt the cyber kill chain. Moreover, compared to traditional defense methods, this scheme demonstrates significant advantages in recognizing unknown attack patterns and acquiring attack intelligence.
