Seven Cybersecurity Trends Reshaping Manufacturing
Summary
Manufacturing’s growing IT/OT connectivity exposes production systems to cyber threats. The article outlines ransomware and supply-chain risks, legacy-system weaknesses, regulatory pressure, and steps such as segmentation, MFA, and limiting vendor access.
Key points
- The article says manufacturing accounted for about 17% of cyberattacks in 2025, up from 9% in 2024, citing a Huntress threat report.
- Ransomware can disrupt production and create financial, equipment, and worker-safety risks, not just affect data.
- Remote maintenance, IIoT sensors, and cloud dashboards can connect previously isolated OT and ICS environments to corporate networks.
- Legacy HMIs and PLCs may be difficult to patch and can retain shared credentials or unnecessary exposed services.
- Recommended controls include network segmentation, MFA, device-health checks, continuous monitoring, and limiting vendor access to necessary systems and time periods.
- Third-party access and persistent VPN connections can provide attackers a route into manufacturing networks.
- The article highlights CMMC 2.0, NIS2, and customer requirements as drivers of governance, asset inventories, access reviews, and incident-response planning.
