Abstract
In one embodiment, a device in a serial network determines that a suspicious event has occurred in the network. The suspicious event is identified based on timing information for one or more frames in the serial network. The device assesses whether the suspicious event is malicious by evaluating a sequence of events in the network that precede the suspicious event. The device causes a mitigation action to be performed in the network when the suspicious event is deemed malicious.
