The expansion of IoT applications allows more remote devices to wirelessly collect, store, and transmit information across vast networks and distances to multiple applications. 
This advancement now demands that remote IoT solutions be designed to have individualized device security, well thought out IoT hardware and with consideration of risk aversion because hackers now have a larger playing field with even more targets. Industries like Smart Grids, Smart Cities, and the Transportation industry are more susceptible to these cyber attacks because they are constantly trying to go further, do more, and expand network coverage. Remote IoT connected devices can be accessed from both wired and wireless networks, which leave them vulnerable to these basic types of attacks to consider:
- Access/Authentication of IoT Devices - Hackers can cause mistrust by misleading remote network devices by altering the manufacturer code.
- Up-to-date security systems - Hackers can attack systems that have fallen behind on updates or lack support to patch issues in large numbers of scattered IoT devices.
- Encryption Network Security - Hackers can easily access and find encryption keys to decrypt IoT data.
- Hardware Port access Protection- Hackers can physically attack remote IoT devices and gain access through the JTAG port, network ports, or an Ethernet port.
The IoT solution to help prevent these cyber attacks is to design and implement a futuristic IoT security framework. The security solution will be tailored to a specific IoT solution and will provide advance features like device authentication, using a remote system that will monitor and update devices. Remote services will also help store IoT data and validate that data as originating from the proper device. It will include a hardened coprocessor that add other layers of IoT security by enabling security functions separate from the main processor in a hardened security environment.
