The Threat of Cyberattacks on Manufacturing Systems

Manufacturers are increasingly utilising sophisticated industrial control systems (ICS) to enhance efficiency and output. However, the greater connectivity and automation these systems allow also introduces significant cybersecurity risks that cannot be ignored.


Predatory hackers are actively targeting vulnerabilities in ICS networks to cause major disruptions. There have already been disturbing real-world examples, like an attack that resulted in molten steel spewing dangerously at an Iranian steel plant. New malware strains engineered to manipulate industrial systems have also been uncovered.


Manufacturers Recognise the Risks


Many manufacturers are wisely re-evaluating their cybersecurity controls. Over 30% of survey respondents from the manufacturing/engineering sector said they plan to review protections in the coming year. This suggests a growing awareness of the threats.


Potential vulnerabilities exist throughout ICS networks, including:


  • Insecure passwords and permissions that allow access

  • Outdated hardware/software components

  • Connecting systems to the internet without proper safeguards

  • Lack of encryption allowing communication interception

  • Social engineering tricks that exploit insiders


Implementing Safeguards


The mosteffective approach combines both technology solutions and vigilant policies:


  • Update hardware/software components regularly

  • Enforce strong, frequently changed passwords

  • Closely monitor network activity for anomalies

  • Isolate ICS networks from external connections

  • Prioritise cybersecurity training to raise awareness of risks

  • Create and rehearse incident response plans to enable rapid containment


Taking these steps will help manufacturers avoid the costly, dangerous consequences of determined hackers penetrating their ICS networks. As systems become more complex, companies must make cybersecurity a top priority throughout their supply chains. Identifying risks and vulnerabilities before they are exploited is fundamental to ensuring operations continue undisrupted while protecting profits.


Ignoring the threat invites catastrophe. But with proactive engagement of the issue, manufacturers can benefit from automation while sidestepping its pitfalls.
