As cyber threats continue to evolve, securing embedded systems has become a top priority for businesses and organizations in the UK. These systems, which control everything from home appliances to critical infrastructure, are increasingly vulnerable to cyber attacks. Embedded cyber security is no longer just a good practice — it’s a necessity. This blog explores why embedded cyber security is so important in the UK and how businesses can protect their systems from cyber threats.

Understanding Embedded Cyber Security

Embedded cyber security is the application of protective measures, such as encryption, secure boot, network security, and patching, which defend an integrated system from being exploited or harmed by accessing its communication interfaces. Embedded systems are cyber-physical systems and have dedicated computing resources, for example, microcontrollers or DSPs, integrated into different types of machines or equipment. These specially designed ‘black boxes’ are usually found in medical devices, automobiles, smart appliances, industrial equipment and much more.

The reliance of modern technologies on the internet creates a new class of threats that can take advantage of these technologies at scale due to the ease of access that comes with being online.

The Increasing Relevance of Embedded Cybersecurity in the United Kingdom

The integration of IoT devices, self-directed systems, and smart technologies has been on the rise in the UK. However, greater connectivity poses greater threats. Here are reasons why embedded cybersecurity is crucial:

The IoT Ecosystem: The UK has literally millions of internet-connected devices, which signifies the exponential growth of the IoT market. A large proportion of these devices have embedded systems which are vulnerable to cyber-attacks. Steps should be taken to ensure that these systems are adequately secured to avert their seizure or usage in botnet-enabled expansive attacks.
Threats to National Infrastructure: Healthcare, energy, and transportation sectors consider embedded systems as foundational. The downside with these systems is any weakness in them can result in power failures, medical services outages, or transport calamitous accidents at worse. They need to be protected for reasons of public and national defense.
Governance: The National Cyber Security Strategy and GDPR indicate that IoT and AI technologies widen the scope of intelligence and data facilities. Because of this, there is increased focus on cyber threats. It can bring a lot of financial burdens alongside reputational damage to businesses operating, making the implementation of proper embedded cyber measures indispensable.
Target for Cyber Criminals: Embedded systems are widely used in our contemporary society, making them subject to attack by cybercriminals. The exploitation of these systems can lead to sensitive information being accessed, operations being disrupted, or even physical harm.

How to Protect Embedded Systems with Cyber Security:

For UK businesses, a blend of methodologies and tools is needed to safeguard embedded systems. Consider these primary strategies:

Secure Development Lifecycle (SDLC): All phases of the development process must integrate security, from designing to testing, deployment, and beyond. This approach aids in reducing risks associated with exploitable vulnerabilities.
Secure Boot and Hardware Security: The inclusion of secure boot procedures and the use of HSMs guarantees that only trusted software is executed on embedded systems.
Regular Updates and Patches: A large number of embedded systems run for years on end without any form of updates. Regular software and firmware updating is critical in removing vulnerabilities that could be misused by aggressors.
Encrypt Data: The encryption of data both stored in a system and in transit makes certain that the sensitive data stays safe even if the system itself is breached.
Access Control: Use strong authentication and authorization techniques to manage the access of users into the embedded system. This minimizes the chances of any unauthorized access occurring to critical information and activities.

Final Remarks

While adopting IoT and smart technologies, optimized systems embedded in devices require the same level of cyber security attention. Adequately fortifying security infrastructure, controlled compliances with industry standards, and other security protocols ensures that UK businesses safeguard their embedded systems from the constantly evolving cyberspace threats, protecting their business operations and customer data privacy. Having robust systems that monitor activities within devices is not mere technical compliance, it is a requirement for a secure and reliable digital ecosystem.
