Securing IoT top priority for enterprises, research says

Securing Internet of Things devices is a crucial goal for every enterprise, according to global tech market advisory firm, ABI Research.

It says integrating security into IoT projects may not be an easy feat, but is an increasingly urgent necessity.

“With an installed base of 44 billion connected devices projected for 2023, the amount of data and information generated and shared will reach zettabytes of data,” says Michela Menting, digital security research director at ABI Research.

“Much of that data will be sensitive, whether about an individuals privacy or confidential business information. As such, it presents a lucrative opportunity for threat actors, as data has become a highly commoditised asset in modern societies,” she explains.

“Add to that the potential of harnessing unprotected IoT devices for botnets, denial-of-service attacks, or even holding them hostage to ransomware, the imperative for security cannot be ignored.

Menting says several platforms and tools have emerged in the market recently, which can facilitate security implementation, even in the most basic IoT devices.

“From a hardware perspective, many semiconductor manufacturers, such as STMicroelectronics, NXP, Renesas, Microchip, Cypress, Nuvoton, MediaTek, RedPine, and Maxim Integrated, are offering secure microcontrollers that can service general-purpose IoT applications from smart home appliances to industrial control systems,” she explains.

“Boosted by Arms Cortex M4 (and soon M23 and M33 cores), they can enable a host of secure functionalities, including security co-processors and cryptographic accelerators, secure storage for keys and certificates, secure execution environments, and root of trust functionalities.

But beyond that, Menting says these secure microcontrollers come prepackaged with supporting software development tools that can enable developers to leverage these hardware features and deploy secure services, such as key provisioning and onboarding to a cloud platform, as well as lifecycle management (e.g., secure over-the-air software updates).

“In a bid to facilitate secure IoT deployments, the semiconductors vendors offer a wide breadth of software development platforms, from their own proprietary solutions but also focusing on interoperability and compatibility with third-party software and connectivity tools (such as those provided by Segger, Eclipse, Visual Studio, IAR Embedded Workbench, IDE Atmel Studio, Modbus Toolbox, Arm Keil - Pelion, Secure Thingz Deploy Architecture Azure Sphere, AWS - Google Cloud IoT Core, among many others),” she says.

“The aim is to facilitate the use of secure hardware by providing secure software development and service connectivity tools that can easily allow developers to onboard and securely manage their devices,” says Menting.

“Developing and managing secure IoT deployments is no longer the remit of security professionals but is a capability that is quickly becoming available to developers of all levels.

“Enterprises looking to deploy IoT can now more easily engage in securing them, in a more cost-effective manner that can enable faster time-to-market,” she says.

“End-to-end IoT security is within reach for enterprises large and small.”
