The fourth industrial revolution, Industry 4.0, is upon us. It combines information technology (IT) and operational technologies (OT) to enable companies to manufacture anything unprecedentedly.
But these changes also open the door to new threats. Cyberattacks can have a profound impact on the operations of a business. Let’s see the Importance of cybersecurity for smart factories.

Protecting Data
The Internet of Things (IoT) has transformed the manufacturing industry by enabling synchronized and concerted control of factories, plants, and machines. However, it also exposes the systems to vulnerabilities and threats not seen in conventional IT networks.
This is exacerbated by the move to cyber-physical systems, where components communicate via specific protocols in industry networks; the security mechanisms are not as robust as one might hope.
The fact that IoT is a very open environment makes industrial and manufacturing systems vulnerable to cyber attacks, including interference, disruption, manipulation, theft of data or intellectual property, hostile alterations to process controls, sabotage, and even industrial espionage. This can lead to expensive downtime, productivity loss, and even personnel injury or death.
Moreover, the need for more awareness about and commitment to cybersecurity among industrial and manufacturing professionals is a significant concern. As the truism goes: “Security is not an afterthought”; it needs to be embedded within all aspects of design, implementation, and management from the outset.
This can be done through standards, education, and law or regulation, which must be tailored to manufacturing needs. Too often, the implicit assumption is that all computerized systems are just like IT systems; this ignores the nuances of the manufacturing world. It also ignores that such plans constantly change through opaque emergent behaviors and may not be susceptible to simple rules or countermeasures.
Managing Access
Manufacturers need to integrate cybersecurity for smart factories from the start. That means ensuring the security of OT systems during construction and then continually assessing how those systems function to address new threats.
Smart factory technology includes many tools to gather data and monitor manufacturing processes. However, with these tools come vulnerabilities. For instance, an unauthorized person could access online systems containing valuable intellectual property with a simple hacker attack. A breach of this type of data can devastate a company’s business model.
A single cyberattack can negate many of a smart factory’s benefits, including real-time data monitoring and predictive maintenance. A comprehensive cybersecurity strategy adapted to a smart factory’s needs, such as Zero Trust, can help reduce these risks.
A major challenge manufacturers face is addressing cyberattacks on OT systems, which include devices like programmable logic controllers (PLCs), distributed control systems (DCS), human-machine interfaces (HMIs), and industrial IoT sensors.
These are often connected to a corporate network via industrial Ethernet and can be difficult to manage because of their specialized functionality. This creates a large attack surface that is more vulnerable to attacks. These attacks occur when threat actors infiltrate communication channels between a network and an exposed OT system to steal information or inject firmware upgrades into systems while they are operating.
Managing Security
Even if you’re using the latest technology and equipment, it’s essential to implement cybersecurity safeguards to protect against malware attacks that can lead to ransom demands, denial of service, or industrial espionage. This is a critical concern for smart factory operators, especially when a single device could compromise the entire network’s security with a known vulnerability.
Threat actors have much to gain from accessing a smart factory’s information, including blueprints, technical specifications, and detailed processes. This is why it’s important for smart factory integrators to incorporate cyber security into the overall system design, not just at the software level but also at the hardware level, where possible.
Lastly, smart factories rely on many communication methods to function, which can increase the risk of a cybersecurity attack. Man-in-the-middle attacks are common and happen when a threat actor infiltrates a communication method used in a factory to control equipment, transmit data, or monitor operations.
According to a recent report from Capgemini, 51% of industrial organizations believe that smart factory cyberattacks will increase within the next year. However, 47% of these companies need to consider cybersecurity in their factories a C-level priority. This lack of understanding and preparedness can lead to faster detection and slower response times, resulting in costly damage.
Managing Compliance
In the world of Industry 4.0, manufacturing is rapidly transitioning to networks of global software, automated systems, and OT. This shift, the fourth industrial revolution, offers companies new opportunities to create anything-as-a-service business models and lower capital costs. However, this change also carries significant cybersecurity risks. The inherently interconnected nature of smart factories exponentially increases security risks and can create a single point of failure that can cause the whole system to fail.
Cyberattacks are a serious threat to manufacturing systems because they can lead to a loss in production, access to critical data, and, in extreme cases, physical damage to the plant. These attacks often take advantage of common attack methods such as vulnerability exploitation, malware, denial of service (DoS), device hacking, and exposure of human-machine interfaces.
As a result, manufacturers must ensure that all employees know the dangers of cyberattacks and understand how to recognize an attempted attack before it is too late. This should be a part of every new employee’s onboarding and a regular training topic for seasoned team members.
