A method includes detecting, by a Local Control Network (LCN) Monitor, a transmission of a data packet from a first device to at least one second device over the LCN. The LCN Monitor is not a source or destination of the data packet. The method also includes obtaining, by the LCN Monitor, a copy of the transmitted data packet. The method further includes decoding, by the LCN Monitor, the obtained data packet. In addition, the method includes storing, by the LCN Monitor, the decoded data packet in a storage device.
