The various different things that technology provides for our interlinked lives in the current networked world. Whether it is smartphones, smart homes, or hardware board design – as consumers, you now depend on a growth of devices to run our everyday lives smoother and more powerful. Yet with rising dependence on these gadgets, so too do the dangers. One of the side effects of the liberation hardware hacking has given us is a quandary you users must face: how do you maintain open function and convenience against security threats?
Today, with hardware hacking where unauthorised access to or control of electronic devices is achieved by manipulating the physical device consumers and manufacturers have heightened awareness of this security issue. As hackers get more skilled in their hacks, strong security is a necessity more than ever. The problem is how to protect from such exploits but it is difficult to do this without important loss of convenience and functionality.

The Evolution of Hardware Hacking
While hardware hacking is not a new concept, it has changed more than a little from the early days. During the early days of computing, you needed to have physical access to a device before you could try and mess with its hardware. The story since has been quite different, however.
As you move towards wireless tech and the Internet of Things (IoT) hackers are no longer being bricks they can access devices/code remotely. This development has created a situation where hardware security has been forced to become more difficult than it used to be. What used to be “dumb” or closed devices, are becoming smarter and being connected to networks, which means they can now be exploited by all sorts of attackers.
The reasons for undertaking hardware hacks have only, likewise expanded. It’s true that some hackers still engage in these activities for curiosity and the thrill of it, but other hackers have malicious motivations. It has become increasingly clear that financial gain, data theft, or even state-sponsored attacks have emerged as primary motives for hardware hacking efforts.

The Security-Functionality Trade-off
The central issue for hardware security is a fundamental trade-off between security and functionality. It would be wonderful to live in a world where you could have all of our devices entirely secure while maintaining all of the features and luxuries you so desire. Sadly, what actually occurs is quite different in reality.
However, deploying strong security modules may lead to performance or user experience (UX) issues. Close to regular readers will already understand that encryption, though vital for securing the data, is very heavy and can significantly degrade the processing fast, as well as large consumption of electricity. Meanwhile, strong authentication is needed to ward off unwanted access, but it can be annoying for users and lead to annoyance.

The Cost of Ignoring Security
Of course, there’s the real trade-off between security and functionality in any hardware engineering solution, but the price to pay when it comes to neglecting security is just too high. The price of success for a hardware hack should never be so high that any short-term hacks on functionality or user experience justify the cost.
Compromised devices can steal personal data, and lose analytics property rights. for personal users. In some cases, it is even worse for businesses and organisations, where a breached connected device can provide access to an entire network which in turn causes massive data breaches, reputation loss & financial disasters.
Meanwhile, as our lives become more intertwined with computers in all their various forms, the consequences of hardware hacks move from cyberspace into real space. In the era of IoT and smart homes, these are compromised devices that belong to you and someone can potentially hack into your home if they understand which device or vulnerability is easier to exploit to get some physical access like locks, thermostats, or even worse vehicles for personal safety.

Designing for Security
With so much on the line, many manufacturers are now taking a security-by-design approach. This philosophy involves thinking about security from concept to final production of a product.
Threat modelling is a vital element of this concept. Understanding the potential attack vectors and vulnerabilities at the design stage will enable manufacturers to then build suitable protections from day one. This preventative strategy is generally more successful and less invasive than attempting to remedy security vulnerabilities after a product has already been distributed.

The Role of Software in Hardware Security
While the hardware-centric measures are essential, such software-centric ones are crucial in proving to be a saviour when and where hackers make their attempts. Software updates and patches are important to patch the newly discovered vulnerabilities over time.
However, the process of updating is itself a friction point for users. Many updates often disrupt our daily routine and force us to restart if not only disable a few features temporarily. This could help manufacturers more easily walk the line of delivering timely security updates without disrupting user experience.
-
User Education and Empowerment
Manufacturers hold a lot of the responsibility when it comes to device security, however, users are just as important. The most secure device can always be put to harm if used carelessly or configured wrongly.
Therefore, to build the robust security thinking that is part of a modern security strategy, user education is central. This includes more than just educating users about potential risks & best practices, it should involve creating user interfaces and experiences that mitigate insecure behaviour.
For instance, these days security setup wizards are included with many of the devices that help walk users through configuring security. Some use nudges and notifications to remind users to update their software or switch their passwords regularly.
Conclusion
Ultimately, the effort to strike a balance between security and utility, especially when designing embedded hardware, is not just about ensuring that our devices are secure — it is about maintaining the trust and certainty to safely fulfil technology’s promise of making life easier. This must be our goal, as you work through this complex terrain together.
