5 IOT Data Flow Within the Site Capture Code Transmit RAN Transport IP, MPLS, etc. Store Analyze Action Sensors IoT nodes Part of Operation Technology (OT); Sensors with analog (0-10V) or digital electrical outputs; Powered by the IOT node or through an external source; The IOT node transforms the electrical signal into data packets; Message Queuing Telemetry Transport (MQTT), Constrained Application Protocol (CoAP) Rugged design; Or Sensors can take form of any IP based protocol. IoT nodes connect one or multiple sensors and translate an analog signal into packets. Copyright 2016 DATACONSULT All rights reserved.

31 Proposed IOT Security Framework Per device: Authentication: endpoints should be fingerprinted. Authorization: establishing the cross platform trust relationships. Network Enforced Policy: all elements that route and transport endpoint traffic securely over the infrastructure. Analytics: Data, generated by the IoT devices, is only valuable if the right analytics algorithms or other security intelligence processes are defined to identify the threat.
