1. A computer system for creating a fingerprint for a device, the computer system comprising the device operatively connected to a device management system, the device management system comprising at least one processor operatively coupled to at least one database, the at least one processor configured for:

  • receiving a first payload from the device, the first payload comprising data in a particular format, a device indicator comprising a unique identifier used for identifying the device, and an indication of a version of firmware running on the device;

    creating the fingerprint for the device, the fingerprint comprising a section format for each of one or more distinct sections of the particular format in a particular order and the indication of the version of the firmware running on the device;

    storing a record of the fingerprint for the device and the unique identifier at the at least one database;

    parsing the particular format of the first payload into the one or more distinct sections of the particular format;

    determining the section format of each of the one or more distinct sections;

    creating a record of the section format of each of the one or more distinct sections in the particular order; and

    comparing a format of each subsequent payload received from the device to the fingerprint for the device to determine whether the device has been compromised.
