In the last decade, the IoT evolution has seen an ever-increasing number of embedded systems – large and small being connecting to the internet – ranging from wearables, smart home devices, automotive, transportation, security, medical, industrial to smart city control systems.
Billions of devices are connected to the internet and a majority are being designed to be remotely managed or field-upgradable from the cloud. This presents a huge landscape for cyber-attacks; from malicious firmware uploads to corrupt the functionality of the device, IP theft within the device or to hijack the device to gain access to the wider network it happens to be connected to.
To counter such threats in your design, the embedded designer now has to consider all aspects in the design that are prone to these types of attack. Typically, a full understanding from the cloud layer down to the gateway, the protocols, types of embedded hardware and memory used is required. For those who are not security experts, this could be a daunting task.
Thankfully, technology companies have not stood still on this subject and have developed robust solutions to help embedded designers on this subject by offering embedded technologies with security built in.
Digi International provides a suite of products which all incorporate their Trustfence® security framework designed to run on the Digi range of embedded products. From the XBee3® wireless control modules, to high performance ConnectCore® CC6UL and CC8x NXP iMX based processor SoMs, Digi industrial cellular gateways.
In conjunction with Trustfence®, there is Digi Remote Manager® (DRM®): a cloud management layer that can be integrated to a variety of cloud platforms e.g. AWS, Azure, Google. By using DRM®, the end products can be deployed, remotely managed and upgraded with a high level of confidence that the network of edge devices remain secure. Preconfigured APIs are available for customers to tailor their DRM® solution for deployment, remote access and management of the assets. A mobile app is also available for DRM®.
