A device may receive a secure signal message from an IoT device provided in a first security zone, and may provide the secure signal message from the first security zone to a second security zone, via a first secure data layer. The device may generate two processed secure signal messages from the secure signal message, and may provide the two processed secure signal messages from the second security zone to a third security zone, via a second secure data layer. The device may calculate a secure analytics message, that includes a graph, based on the two processed secure signal messages, and may provide the secure analytics message from the third security zone to a fourth security zone, via a third secure data layer. The device may store the secure analytics message in a data structure associated with the fourth security zone.
