The present invention discloses a system and method for evaluation and response to cyber security exposure in an embedded control device, and relates to a system and method for evaluating and altering, if necessary, the potential for a cyber security attack on an individual embedded device located on a local network assumed to be protected from outside cyber threats. In a first level of potential exposure, the system attempts to send an outgoing message to a known IP address on a network outside the local network. If the outgoing messages are confirmed as received, the embedded device has access to outside networks. In a second level of potential exposure, the known outside IP address attempts to send an incoming message to the embedded device. If the incoming message is received, the embedded can be accessed from an external network. 本发明公开了嵌入式控制设备中的网络安全暴露评估和响应系统和方法。用于评估和在需要的情况下改变对定位在本地网络上的假设免受外部网络威胁的个体的嵌入式设备的网络安全攻击的可能性的系统和方法。在第级潜在的暴露中，该系统试图将输出消息发送到本地网络外部的网络上的已知的IP地址。如果输出消息被确认为已接收，则嵌入式设备具有对外部网络的访问。在第二级潜在的暴露中，
