How Secure Is Your Manufacturing Operation?

How Secure Is Your Manufacturing Operation?
TL;DR
  • Manufacturing is now a top cyber target due to connected systems (IoT), making operational technology and intellectual property highly vulnerable.

  • Basic security gaps—like default passwords and device names—are still common and create easy entry points for attackers.

  • Strong protection requires network segmentation and layered security tools (firewalls, monitoring, intrusion prevention) to reduce risk and limit damage.

 

After the public and finance sectors, the manufacturing industry is the third most targeted by cyber-attacks, as the threat from malicious hackers, cybercriminals and corporate espionage escalate. The fact that industrial processes are increasingly connected - via the Internet of Things (IoT) - which makes their software and advanced automation vulnerable to a security breach. This can result in a loss of sensitive corporate and intellectual information, which could compromise your profitability, damage your brand and worse.

This is why you have to actively manage the security risks by:

 

1. Being password smart

The first step is the most obvious: Change default passwords. The number of production manufacturing and process control systems that still use the factory-assigned passwords is staggering. These passwords tend to be readily available via a Google search, so continuing to use them is the electronic equivalent of leaving the key in the lock of your front door.

 

2. Default names

Step two is similar: Change the default names of devices and networks. This is another very, very basic step, but one that far too many manufacturers fail to take when deploying control systems.

 

3. Ring-fencing your networks

Treat your core network like you treat your business network - and keep the two separate. Each of these is important, but many manufacturers treat one as more important than the other. In actuality, the two are related in what they do for the business and why they can be critical for safe manufacturing.

Treating the core network like the business network means ring-fencing your manufacturing network, in the same way you secure the financial and IP portions of your business. Separating the process and business networks is important because it is too easy for a vulnerability in one of the networks to introduce malware for the other.

Business-side users, for example, may be more likely to use USB thumb drives that could carry malware targeting industrial controllers. And a poorly defended manufacturing line might provide an easy attack vector for malware that could move into critical databases.

 

4. Taking a layered approach to security

Taking a layered approach to security is the most secure option for any operation, no matter the scale or size. Here you need to employ a wide range of tools and techniques from firewalls and intrusion detection systems, to anti-virus systems and 24/7 network monitoring tools. Firewall and IPS (Intrusion Prevention System) or a UTM (Unified Threat Management) control traffic in and out of your network, and will pick up unusual traffic and ensure any intrusion is detected.

It is up to manufacturers to ensure that they have systems and procedures in place to protect sensitive data, and mitigate against any active threats to their networks and IT infrastructure. Fail to do this and you risk brand reputation and profitability – something no operation can afford in this digital era.

Frequently asked questions

1. Why is manufacturing a major target for cyber-attacks?

Manufacturers rely heavily on interconnected systems, automation, and IoT devices. This creates more entry points for attackers, and the payoff is high—intellectual property, production disruption, and financial data all have significant value.

2. What are the biggest cybersecurity mistakes manufacturers make?

The most common issues are surprisingly simple: leaving default passwords unchanged, keeping default device names, and failing to properly separate business and production networks.

3. What does “ring-fencing” a network mean?

It means segmenting your manufacturing (OT) network from your business (IT) network. This prevents threats in one area—like malware from an employee device—from spreading into production systems or vice versa.

4. What is a layered security approach?

Layered security uses multiple defenses working together, such as firewalls, intrusion prevention systems (IPS), antivirus tools, and continuous monitoring. If one layer fails, others still provide protection.

5. How can a cyber-attack impact a manufacturing business?

Beyond data loss, attacks can halt production, damage equipment, expose sensitive designs, and harm your reputation—ultimately affecting revenue and long-term business growth.
