Abstract
A plurality of digital data packets may be received via a wireless data interface, wired data interface, or data path. Code may be executed for a data communications protocol in which one or more of the filtered digital data packets causes the code to transition to different states of the protocol. A protocol state machine may be executed comprising a plurality of states and a plurality of transitions between the states to simulate correct execution of a particular data communication protocol. An anomaly may be detected between a first particular state of the protocol during the execution of the code and a second particular state of the protocol state machine, and in response, an anomaly event may be generated comprising digital data indicating that the anomaly has occurred. An anomaly event log based on the anomaly event and the filtered digital data packets may be transmitted to a computing device.
