Industrial Cyber Security: Stable & Secure

Digitalization is fundamentally changing the manufacturing industry: networked machines, IoT sensors, and automated production processes increase efficiency, but also create new areas of vulnerability. Cyberattacks on production facilities can paralyze entire supply chains. OT-Security (Operational Technology Security) is therefore an indispensable part of any modern production facility today. It not only protects systems and data, but is also an essential component of production security and competitive strength.

In contrast to traditional IT, the focus in production is on availability. A cyber attack can not only jeopardize data, but also impair operations - with enormous economic consequences. At the same time, many systems are designed for longevity and are not intended to meet current security standards.

• Old systems (legacy OT): Decades-old control systems are often unable to be patched or are challenging to secure.
• Networked production environments: IT and OT are increasingly merging, making it easier for malware to migrate from office IT environments to production systems.
• Remote maintenance access: External service providers frequently access machines directly - often with inadequately secured accounts.
• Regulatory requirements: Regulations such as the NIS2 directive, KRITIS, or IEC 62443 (an international series of standards that defines IT security for industrial automation and control systems) require comprehensive security measures that also include OT.

This poses specific challenges for the manufacturing industry: Production facilities, remote maintenance access, IoT sensors, or networked logistics systems must be secured in such a way that they do not become a weak point.

A structured approach to OT security offers manufacturing companies several advantages:

• Increased operational reliability: Failures can be avoided through segmentation and monitoring.
• Early detection of attacks: Security incidents can be detected and limited more quickly.
• Compliance with regulatory requirements: Requirements from NIS2, KRITIS, or IEC 62443 are specifically addressed.
• Transparency about systems and risks: A comprehensive overview of all OT components provides the basis for informed decisions.
• Long-term resilience: Continuous improvement strengthens the strength of the production environment.

1. Carry out an initial analysis of your OT infrastructure. Which systems are running, how are they networked, and which access points exist?
2. Develop a security concept tailored to your production, with a focus on segmentation, access control, and monitoring.
3. Implement step by step – without jeopardising your production: e.g., passive sensors, monitoring solutions, protection of remote maintenance access.
4. Establish 24/7 monitoring with a SOC and define transparent processes for vulnerability management and incident response.
5. Focus on continuous improvement - regularly analyze your threat landscape and adjust your measures accordingly.

With the right OT security strategy, you not only protect your production facilities from cyberattacks and ensure production security, but also secure your production capability, competitiveness, and corporate image in the long term.
