Securing Manufacturing Lines From the Inside Out
Industrial Cybersecurity: Protecting Manufacturing Automation Systems
Manufacturing faces unprecedented cybersecurity challenges today. Companies must secure industrial automation and control systems effectively.
Manufacturing Cybersecurity Threat Landscape
Manufacturing remains the primary target for cyberattacks globally. Over 25% of all incidents impact this sector specifically. Digitalization expands operational technology attack surfaces significantly. Companies must prepare for inevitable security incidents.
Prevalent Attack Methods and Vectors
Ransomware dominates manufacturing cyber incidents at 68%. Business email compromise attacks increase frequency recently. Account takeovers provide unauthorized network access. Web-based attacks and DDoS incidents complicate security further.
Real-World Manufacturing Security Incidents
Recent cases demonstrate attack severity and impact:
- Clorox disclosed unauthorized IT system activity in 2023
- Operations disruption affected multiple manufacturing sites
- Varta disconnected IT systems following 2024 cyber incident
- Production halted for over two weeks during recovery
- Halliburton suffered ransomware attack in August 2024
- Attack caused $35 million losses and stock decline
Industrial Automation Security Challenges
Manufacturers face unique operational technology challenges:
- IT/OT convergence exposes legacy control systems
- Aging PLC and DCS infrastructure resists patching
- Third-party vendors introduce additional risk factors
- Cybersecurity talent shortage affects manufacturing specifically

Frequently Asked Questions
Why does manufacturing attract so many cyberattacks?
Manufacturing offers high disruption potential for attackers. Operational continuity represents critical business value. Legacy systems often lack modern security protections.
How can companies protect legacy industrial control systems?
Network segmentation isolates legacy PLC and DCS systems. Access controls limit exposure to threats. Monitoring detects anomalous behavior effectively.
What makes industrial cybersecurity different from IT security?
Industrial systems prioritize operational continuity above all. Legacy equipment cannot run traditional security software. Safety implications exceed typical data protection concerns.
