PCB Manufacturing Cybersecurity Risks: Decoding The Risk in 2024

You can imagine going to any kind of factory or laboratory where you walk through a labyrinthine floor, vivid with activity, and possibly robotic arms whizzing and whirring, while highly-skilled technicians buzz around.

None of this would be possible without printed circuit boards (PCBs) which are the backbone of any high-tech choreography. PCB is making tiny hearts of tech devices beat silently and efficiently.

But here we are, in the year of 2024, where a lot of innovations are coming to life. Also, when the technology advances, so do risks and breaches.

Now, before you roll your eyes and think, “Not another cybersecurity scare story,” let’s try to explain these risks in a way that any plot twist in a thriller novel could be satisfied with.

Just think about this: from the beginning of this year, 60% and more say that external factors are most likely to be a cybersecurity risk for companies and businesses around the world. On the other hand, 31% think the threat will come from within. It looks like you can never be too careful.

And if, at any time, the plot looks like it came from science fiction, remember that we live in a world of technology, and that AI is our new best friend. So yes, the future is now. The question is, can we protect ourselves from it?

The heartbeat of modern electronics

Every day you use your smartphone, laptop, car, fridge. PCBs are part of these devices, and without these boards, we would hardly be able to imagine the modern world of today. These intricate green boards are the foundation upon which microchips and electronic components rest. They connect everything into a seamless whole.

However, today, as manufacturing PCB boards becomes more advanced and processes more interconnected, the potential attack surface for cyber threats is getting alarmingly wide.

Imagine it like this: in the past, making a PCB manufacturing plant secure looked very much like guarding a castle. You would have high walls, a moat, and maybe a dragon or two to keep intruders at bay. Today, the castle is digitalized–it has IoT devices, AI-driven machinery, real-time communications, digital highways. And each connection, each piece of code, is a potential entry point for cyber rogues.

Now it’s the time to go through those exciting thriller plots.

The rogue’s gallery

Cyber threats in PCB manufacturing could be exciting just as equally as terrifying. The prime step is to know how your enemies think and work, so you can protect yourself accordingly. According to a study, by the year 2025, cybercrime can cost companies and businesses up to 10.5 trillion US dollars per year. Just for comparison, in 2021 cybersecurity cost 6 trillion US dollars annually.

Here are some of the main scenarios:

Industrial espionage

So, here is this rival company that’s trying to take a peek into your blueprint for the next-gen PCB that’s going to revolutionize the market. They’re not just stealing ideas–they’re taking away years of your research and millions of your dollars.

These spies are nothing like those you could’ve read about in books. They don’t burst into action–they can lay dormant for months, use sophisticated malware to infiltrate networks, and diligently collect data.

Ransomware attacks

One fine morning you walk into the plant only to find that your systems are locked down, and there is a cheeky message asking for, let’s say, cryptocurrency in exchange for access.

This one is straightforward but devastating. Cyber thugs infiltrate the network, encrypt data, and hold it hostage. What’s unnerving is that you don’t get to see the person behind this attack. You may never know who your attacker is. And yet, there might be nothing you can do.

Supply chain attacks

This is a classical Trojan horse scam. Attackers can use someone else to penetrate your data and do their worst. Usually it goes through a seemingly innocuous update from a trusted supplier, with a hidden surprise inside.

How does it work? Attackers compromise a trusted third party and use it to get to you.

Intellectual property theft

This is a nightmare of every intellectual worker–to find your designs, manuscripts, blueprints, and trade secrets vanish without a trace. Next time you see them, they are in the hands of a competitor.

Can you prove the property is yours? Or the traces of all your work progress are gone too? Cyber thieves use advanced persistent threats (APTs) to keep long-term access to the target network.

Denial-of-service (DoS) attacks

Your production line just goes to a halt as network traffic surges to unbearable levels. This can happen if you are an online bookstore and you’re giving a complete discount, which results in too many people on your site, which ultimately crashes down. Too much traffic can do that (also, not to mention the collective power of readers united).

But, if you’re not selling books and everything stops nonetheless, you can probably blame attackers that flood the network with traffic, thus overwhelming servers and causing disruptions.

The digital knight in shining armor

What can you do? How do PCB manufacturers protect themselves, apart from calling Chuck Norris or some other action hero to catch a spy, that is.

The answer is in a multi-layered approach to cybersecurity. Or, as you can call it, fortifying the castle.

Network segmentation

Think of it as building walls within walls. By segmenting the network, you can contain breaches and limit the movement of intruders. Just like when water starts getting into the submarine–the submarine is compartmentalized and the segment where water breaches gets closed.

This way you’ll have critical systems isolated from less secure areas prone to attacks, and access is tightly controlled.

Advanced threat detection

Get the best army to guard your castle. Better yet, find a dragon that never sleeps. In modern words, try out AI-driven threat detection systems that can monitor network traffic. AI has this unusually convenient feature where it can analyze patterns to identify potential threats in real-time.

Zero trust architecture

‘Trust no one’ might sound paranoid, but in cybersecurity it’s a wise mantra. In the spirit of this wisdom, every user, device, and application must prove their legitimacy before they get access. This procedure significantly reduces the risk of insider threats.

Regular audits and penetration testing

Once in a while you need to inspect your castle and its defenses, see where it can be upgraded, what parts could be replaced, which places are the weakest. Periodic inspections and stress tests make sure that your securities are up to the task.

For that reason, cybersecurity teams regularly audit systems and make penetration tests to identify vulnerabilities that can be fixed.

Employee training and awareness

Even the mightiest fortress can fall if the guards are asleep at their posts. So what can you do? You can educate your employees through various training programs about the latest threats and safe practices. That way, beside the digital programs and systems, you’ll also have a human firewall.

Secure supply chain practices

The chain is strong as the weakest link. So make sure that every link is fortified, from the blacksmith to the baker. They might not be using the same weaponry, but they can use what makes them the best.

As a manufacturer, you can encourage strong security protocols, and monitor third-party interactions closely.

The double-edged sword

The human factor can easily be a double-edged sword when fighting cybersecurity threats. Human genius and creativity drive innovation, but they can easily be a weak link. Just think about this: a careless click on a phishing email can undo even the best defenses.

It’s important to create a culture of security awareness. It’s not just about following rules–it’s about creating a mindset where every employee understands the risks and acts like a guardian of the digital realm.

The cyber knight’s call to arms

For a long time, cybersecurity was not just a technical requirement but a strategic imperative. As a manufacturer, you need to embrace a holistic approach, mixing cutting-edge technology with a culture of vigilance and resilience. The digital knights of the modern age are armed with firewalls, encryption, and AI. They stand guard over the precious intellectual treasures.

Remember that cybersecurity is not something you do once. It’s a continual journey where you not only constantly inspect the walls and guards, but you also get to track innovations in the field and implement them as you go along. The threats will evolve, but so will your defenses.

Stay one step ahead of the rogues and make sure that the heartbeat of modern electronics–PCBs–stays strong and true.
