The Internet of Things (IOT) is one of the world’s fastest growing technological revolutions, with billions of devices linked in homes, smart factories, offices, and even remote locations


.However, as the Internet of Things grows in popularity, so do the potential entry points for malicious attackers. Because machine-to-machine (M2M) communication is central to the Internet of Things, these attacks are far more serious than ‘normal’ computer attacks because actual physical machines can be taken over.


The importance of IOT security

IOT securities can be used in large number of businesses are banking on the myriad of applications that use cloud services and artificial intelligence to deliver revenue streams for part of all their future success. In fact, Cisco recently

estimated that, this business sector will contribute $19 trillion to global GDP over the next five years.

The threat is very real and global, affecting many large commercial and government organizations. Because many IOT devices are directly connected to machinery and infrastructure, attacks on IOT infrastructure have reportedly resulted in the shutdown of steel plants, power stations, major businesses, and even a nuclear facility. According to In control, 71% of consumers are concerned that their personal information will be stolen, which is clearly slowing the adoption rate of this new technology.

As new IOT technology is developed, the ‘bad guys’ develop ever more sophisticated ways to circumvent security measures. Physically probing the ICs, analyzing electromagnetic emission, and inducing faults in operation through power supply manipulation are all popular methods.

IOT SECURITY by design

Security by design is a methodology that ensures security is a primary goal throughout the product development and deployment process.

IoT Security: Protecting Your Company's Connected Devices

It addresses the issue that security considerations were frequently included late in the design and prototyping phases of many historical hardware deployments and instances of IOT design.

Security requirements may be added on as a result of prioritizing speed to market or other design considerations. The end result?

Because IOT security cannot be easily retrofitted, this approach has previously resulted in serious security breaches.

Unsecured devices that allow attackers to breach an otherwise secure system, or large numbers of connected devices that cannot be upgraded to deal with emerging threats, are prime examples.

IOT solutions are frequently deployed in large numbers, sometimes in remote locations.

Why is IOT Security by Design required?

Because IOT solutions are frequently deployed in large numbers, sometimes in difficult-to-reach locations. For the past decade or so, pre-planning and foresight have been critical to the integrity of IOT applications.

IOT products are not governed by security procedures or standards. Connected devices are not always secure, and in some cases, they were never intended to be connected to other systems or applications in the first place.

As the security architect for IOT solutions, you must define a strategy for hardware, applications, communication layers, and storage that meets the security requirements of your organization.

The three keys to a secure-by-design environment The Thales Security by Design approach ensures that IOT security is considered from the start of project design. A successful security architecture ensures that devices are protected in the appropriate location and at the appropriate level to meet the requirements of each implementation.

1.You list your threats, vulnerabilities, the likelihood of an attack occurring, and the impact of that attack.

Then, choose appropriate countermeasures.

2. Thales’ security by design strategy continues with the implementation of a solid foundation of trusted digital device IDs and credentials securely stored in device roots during manufacturing. Trusted credentials protect against device cloning, data tampering, theft, or unauthorized access.

3. Thales recommends storing IDs and credentials in a tamper-resistant Secure Element to protect physical and digital access in extra sensitive IOT applications such as automotive, healthcare, and smart grids.

Approach to security by design at the start of IOT projects

Devices that are reliable IDs and credentials are embedded during the manufacturing process.

IDs and credentials should be kept in secure hardware containers.

The foundation of any secure IOT deployment is security by design. Pre-embedded IDs and encryption keys are critical components for secure data encryption, digital message signatures, and over-the-air device and security updates.

Securing data as it travels to the cloud

Protecting a single device is insufficient; security by design must consider what happens when that device is connected to a network.

Pre-embedded keys and credentials are essential for faster data enrollment in IOT cloud platforms.

What is cloud security?

Keys and credentials ensure that IOT devices are authentic and trusted by legitimate partners.

Essentially, this means that external platforms recognize devices right away, and trust is quickly established for future data exchange.

Furthermore, Thales employs strong encryption technology to safeguard data integrity and ensure that only authorized devices and apps have access to data via secure digital signature schemes.

Data should be protected once it reaches external platforms.

IOT device security lifecycle management

Managing the lifecycle of security components across the device and cloud spectrum to reduce attack surface is critical to a strong and long-term digital security strategy, but it is frequently overlooked.

The Solution to Secure Across the 5 Stages of the IoT Security Lifecycle

Security is not a one-time activity, but rather an evolving component of the IOT ecosystem that should support the lifecycle of IOT deployments in:

Introducing new devices while decommissioning others,

Introducing new cloud platforms,

Performing safe software updates,

Implementing controlled key renewals,

Keeping large fleets of devices in good working order.

All of these activities necessitate comprehensive identity, key, and token management.
