1. A system comprising:
hardware circuitry that one or more of includes or is connected with one or more processors configured to be disposed onboard a vehicle system formed from one or more vehicles traveling together along a route, the one or more processors configured to examine one or more characteristics of an incoming data signal received by the one or more processors from a communication device disposed onboard the vehicle system, the one or more characteristics that are examined by the one or more processors including a speed at which the incoming data signal is communicated, the one or more processors configured to determine whether the incoming data signal is a secure data signal or an insecure data signal by comparing the speed at which the incoming data signal is communicated with a range of acceptable communication rates, the one or more processors configured to determine that the incoming data signal is not the secure data signal or is the insecure data signal responsive to the incoming data signal being communicated at a communication rate that is faster or slower than the range of acceptable communication rates, the one or more processors also configured to communicate the incoming data signal to one or more onboard systems of the vehicle system for use by the one or more onboard systems in controlling operation of the vehicle system responsive to determining that the incoming data signal is the secure data signal, and to prevent the incoming data from being communicated to the one or more onboard systems responsive to determining that the incoming data signal is the insecure data signal.
