Cyber Security in mechanical engineering

Why cyber security needs to be built in from the start

In today's interconnected world, machines and systems are increasingly becoming targets for cyberattacks. The field of mechanical engineering is no exception. As digitalization and Industry 4.0 are implemented, the risks grow that attackers may exploit vulnerabilities in machines or plants. This is why cyber security in mechanical engineering is more than just a buzzword – it's a must.

Why cyber security in machines and systems is important?

Machines and production systems are no longer isolated. They are part of a larger network that exchanges data and processes information in real-time. This connectivity brings many benefits, such as increased efficiency and flexibility, but it also introduces new risks. If an attacker gains access to a system, the consequences can be severe: production downtimes, data loss, or even damage to machines and equipment.

That’s why machine engineers must integrate security considerations into their designs from the very beginning. It’s not enough to retroactively address vulnerabilities or hope that an attack won’t happen. To remain secure and competitive in the long run, cyber security must be an integral part of the entire development process.

Key requirements: NIS-2 and the Cyber Resilience Act (CRA)

For companies in mechanical engineering, there are now legal requirements governing cyber security practices. Two important are the NIS-2 Directive (Network and Information Systems Directive) and the Cyber Resilience Act (CRA). Both aim to improve cyber security in critical infrastructure.

The NIS-2 Directive mandates that companies take measures to protect their networks and information systems (IT and OT). This involves not only defending against cyberattacks but also the obligation to identify and address vulnerabilities early on.

The Cyber Resilience Act contains requirements for the cyber security of products. The goal is for machines and products to be designed from the outset in a way that minimizes risks and is secure from potential threats. The CRA also contains requirements for the subsequent life cycle. Weak points in products must also be identified and rectified after delivery.

Staying secure with confidence

Cyber security in mechanical engineering is no longer an option— it’s a necessity. When machine engineers take these principles seriously and integrate cyber security from the outset, they can not only make their machines and systems more secure but also build trust with their customers. In an age when cyberattacks are becoming increasingly sophisticated, it is essential to act proactively and with foresight. This means designing machines, plants, and systems not only to function but also to meet the highest security standards — and to do so sustainably.
