物理隔离网络电磁信息安全检测模型与应用探索

Security Detection Model and Application of Electromagnetic Information in Air-gapped Network

物理隔离网络一般是指与互联网实现物理隔离的内部网络。通过构建隐蔽的声、光、电磁等物理信号,可以建立隐蔽的传输通道,打破物理隔离,造成信息泄漏、病毒植入等广义电磁信息安全问题。在发射、传输、接收的正常通信模型基础上根据检测对象来建立物理隔离网络电磁信息安全检测模型,并针对不同的安全威胁场景,从检测对象和检测方法的角度丰富电磁漏洞检测技术体系,推动新的检测应用探索。

The air-gapped network generally refers to the internal network which is air-gapped from the Internet.Through the construction of hidden physical signals such as sound,light and electromagnetic,hidden transmission channels can be established to break physical isolation be broken,and information leakage,virus implantation and other broad electromagnetic information security issues be caused.Based on the normal communication model of transmitting,transmission and receiving,the electromagnetic information security detection model of air-gapped network is established according to the detection objects.In addition,in view of different security threat scenarios,the electromagnetic vulnerability detection technology system is enriched from the perspective of detection object and detection method,and new detection application exploration is promoted.
