The Importance of Security by Design for IoT Devices

Considering the potential economic advantages and disruptions these devices might bring, security worries exist about them since IT firms find it difficult to safeguard them from possible attackers.

Why is IoT security crucial?

Since IoT is the backbone of the internet, linking devices to the internet and one another, security for IoT is vital. It uses techniques including encryption, authentication, and authorization to safeguard homes, data, and privacy. The Internet of Things has started a revolution that is reshaping our lifestyle, work environment, and transport, and businesses are leading this change. However, because linked devices must be safe, they also pose security threats in smart factories. Hacking can lead to the theft of user capabilities and data from connected devices. Industrial IoT is crucial for preserving functioning and safety; therefore, it shouldn’t be disregarded.

So, how can IoT devices be secured? The solution is Designed for Security

A method of software and hardware development known as “security by design” incorporates security from the start rather than adding it on after a hacking event. The proliferation of IoT products for consumers and businesses by internet companies has made security by design imperative. Due to their widespread Internet connectivity, these Internet of Things gadgets are susceptible to remote hacking. Furthermore, the majority of these items were created without any security features, which makes them simple pickings for security lapses. Three tactics should be used by businesses to increase customer security and privacy, which will increase confidence in IoT devices:

1. Use security in the design

Thus, security should be the first consideration in any Internet of Things architecture. Both startups and large IT companies should include a variety of IoT security measures in the original design phase.

2. Use as much data as needed

IoT makers should use several strategies to prevent the device from being accessed by anyone via the Internet to prevent security breaches.

3. Boost transparency and provide customers notice of and a choice over unforeseen data uses

IoT manufacturers are required to inform users about how their data is used and shared, as well as provide them with options to stop specific data collection and sharing methods. Additionally, they must inform customers about end users’ security so that nobody dangerously uses their IoT devices.


Governments are moving to protect gadgets with internet access. The rule forbids easy-to-guess default passwords and imposes additional cybersecurity obligations on producers and retailers of consumer electronics with internet connections. To safeguard user data and guarantee that wireless gadgets are secure for sale, the EU has also established standards. To build a more secure basis for connected automobiles, smart cities, and other Internet of Things applications, similar activities are underway in the United States of America (USA). Manufacturers must establish a more open protocol for the duration of security upgrades for connectable items and improve the public reporting mechanism for vulnerabilities. IoT devices should go through certification, just like a car needs to be judged roadworthy or a boiler needs to pass an inspection.
