According to one aspect, a method includes obtaining a command on a vehicle, the command being arranged to identify a first action to be taken by the vehicle, wherein the vehicle is in a first vehicle state and the command has a first command state. The method also includes determining, on the vehicle, whether the first command state is consistent with the first vehicle state. When it is determined that the first command state is consistent with the first vehicle state, the method includes executing the first command. When it is determined that the first command state is not consistent with the first vehicle state, the method includes identifying the first command as an illegitimate command and ignoring the illegitimate command.
