IT Security Standards for Connected OT

The convergence of Information Technology (IT) and Operational Technology (OT) in production demands clear responsibilities. While convergence enhances efficiency and insights, it also introduces new security risks. The Industrial Internet of Things (IIoT) amplifies complexity, and vulnerabilities in OT can pose a threat to the entire network.

Integrating IT and OT requires well-defined responsibilities and strategies to minimize conflicts. Network infrastructure, industrial security, and data management are potential conflict areas. Balancing needs is essential: IT emphasizes flexible networks, while OT requires stable infrastructure.

Compliance adherence, such as the new EU directive NIS-2, is increasingly crucial. Internationally recognized standards like ISO 27001 and IEC 62443 come into play. Often outdated, OT can become a weak point, endangering the entire network.

Without proper security measures, OT becomes a target. Insufficient segmentation, insecure authentication, and lacking monitoring elevate the risk. Coordinated efforts between IT and OT are necessary for secure convergence.
