A communication network implements a Universal Measurement and Calibration Protocol (XCP) policy. The communication network includes a plurality of nodes, each of the nodes being operably connected to a bus to send and to receive data communications to and from others of the plurality of nodes. Certain of the data communications include a Universal Measurement and Calibration Protocol (XCP) identifier indicating the presence of XCP protocol within the data frame. At least one of the nodes is configured to mitigate identified XCP protocol in accordance with the policy.
