Design and simulation experiments of the security model for edge devices of government terminal networks

Due to the significant asymmetry between the high frequency of access and the low protection level of government networks and their edge devices, there is a considerable risk of being targeted by hackers. This study initially presents an overview of government terminal network edge devices, proceeds to analyze the security aspects of these devices, and subsequently puts forth a security model design aimed at mitigating the identified issues and vulnerabilities that could potentially result in unauthorized intrusions. Finally, by utilizing some common technologies through simulation experiments, a cost-effective, high-performance, practical, and close-to-real-world security system is designed. The simulation experiment results demonstrate that this model design can achieve automatic defense against network intrusions, ensuring the reliability of government terminal networks and their edge devices, thereby strengthening the security of government terminal networks.
