The Internet of Things (IoT) is gaining popularity, highlighting the potential of digital transformation. As the deployment of IoT devices expands into new markets, the number of unsecured devices grows, as does the number of cybersecurity attacks.
Digital transformation is growing at an unprecedented rate. According to the Statista Research report “Internet of Things – number of connected devices worldwide 2015-2025,” over 74 billion IoT devices will be powering digital transformation, by 2025.
Each connected device adds a new level of connectivity, efficiency and service to the equation. However, as the number of IoT devices increases, so does the level of security risk. As a result, Original Equipment Manufacturers (OEMs) are under increasing pressure to ensure that all of their connected devices meet cybersecurity baseline criteria. The fragmented environment of IoT security has added to the complexity, and a lack of expertise can prevent the proper security countermeasures from being implemented.
Here are five critical steps OEMs can take to simplify security and minimize the time and cost of incorporating appropriate security into their devices from the bottom up.

Security framework
When creating a new IoT device, it’s critical to understand the security requirements for that device. This necessitates a threat model that takes into account the assets of the device, as well as the risks in scope, resulting in a set of security functional needs unique to the device and its use.
Security frameworks for the Internet of Things (IoT) democratize security. Even if there isn’t a team of security professionals, they make it faster, easier, and more cost-effective to create a secure product. They also standardize security, ensuring that the ecosystem’s design and execution are consistent.
Threat model and security analysis
The Threat Model and Security Analysis (TMSA) is the next step in the security process, and it aids in the establishment of a best-practice audit trail. By conducting a TMSA, security professionals will be able to identify the risks to the device and the steps that need to be taken to keep the device and the data it creates secure.
A TMSA helps to avoid over-investing or under-investing in security at the outset, reducing the likelihood of costly changes later in development. It will also aid in the integration of security into all layers of the device.

Root of Trust
The primary result of the threat model should be a determination of the robustness of the chip’s Root of Trust’s – does it need to safeguard against just remote scalable software attacks? Is it also necessary to protect against significant physical attacks? Protecting the device against software attacks may be sufficient for most consumer items with unique keys or certificates per device. Protection against physical attacks is likely to be required if the assets are extremely valuable and if the device has a shared private key.
Third-party evaluation and certification
Brands must also show their investment in security so that customers can trust their products. A third-party evaluation will offer customers the peace of mind and this will allow businesses to scale deployment.
Independent security specialists will evaluate the implementation against best practises, as well as standards, regulations and baseline criteria and adequate actions have been taken, the certification is awarded.
