Abstract:

The networked air and missile defense system has the ability to flexibly control combat resources， effectively realize dynamic cross-domain command and control， and efficiently complete combat tasks. However， networked and integrated operations increase the risk of weapon systems suffering from cyber attacks while improving combat effectiveness， which will seriously threaten network security and combat effectiveness of combat equipment. Taking the U.S. tactical-level air and missile defense system as an example， according to its networked combat characteristics， this paper analyzes the security vulnerabilities of the air and missile defense network， and constructs an assessment model to analyze the probabilities of destroying network nodes. Three indicators are designed and used to evaluate the network performance loss of the node suffered network attack. The OPNET platformand the NetworkX are used to carry out network simulation experiments. Based on the evaluation results， the network defense strategies are proposed to provide reference for the improvement of the security defense capability.

Key words: air and missile defense system, networking, network attack, effectiveness evaluation, security defense, security vulnerabilities

摘要：

网络化防空反导体系能够灵活管控作战资源、有效实现动态跨域指控、高效完成作战任务，然而网络化、一体化作战在提升作战效能的同时，增加了武器系统遭受网络攻击的风险，将严重威胁作战装备网络安全及其作战效能。以美军战术级防空反导体系为例，针对其网络化作战特点，分析防空反导作战网络的安全脆弱性，构建网络攻击风险评估模型，评估网络节点被毁瘫风险。设计指控连通度、指控网络效率指标和网络通信效能指标，旨在利用其评估节点遭受网络攻击的效能损失。利用OPNET网络仿真平台和Python NetworkX库，开展网络攻击仿真实验及效能评估。基于网络攻击效能评估结果，针对性地给出网络安全防御策略建议，可为防空反导体系安全防御能力提升建设提供一定参考。
