摘要： Techniques are provided for cyber warning. One technique includes a cyber warning receiver (CWR). The CWR includes a bus sensing circuit to sense traffic on a communications bus over time, an anomaly detecting circuit to detect anomalous behavior in the sensed bus traffic, a data fusing circuit to fuse the detected anomalous behavior into groups having similar characteristics, a decision making circuit to decide if the fused anomalous behavior is normal or abnormal, and a behavior logging circuit to log the detected anomalous behavior on an electronic storage device. In one embodiment, the CWR further includes a behavior alerting circuit to alert an operator to the fused anomalous behavior identified as abnormal. In one embodiment, the communications bus is an embedded communications bus, such as a MIL-STD-1553 bus, and the CWR is a standalone device configured to connect to the MIL-STD-1553 bus as a bus monitor.
