Challenge

As data centers integrate IT and OT systems for smarter, more efficient operations, OT security must match IT protection standards. Increasing connectivity of power, cooling, and access control systems expands the cyber-attack surface. At the same time, OT environments are difficult to update without risking operational disruption, while strict cybersecurity standards add further complexity.

Solution

Siemens enables secure IT/OT convergence through a lifecycle-based cybersecurity approach. We help protect critical infrastructure with segmentation, secure communications, and governance aligned with international standards. Applying Zero Trust principles to OT environments enables secure connectivity, resilience, and compliance without compromising performance or availability.

Know the threats to stay ahead

Amongst the most connected OT systems in a data center are:

  • Physical security / access control
  • Fire systems
  • Uninterruptible Power Supply
  • Generators
  • Data center infrastructure management

Each connection expands the potential attack surface. Cyber threats often exploit human error, insider risks, and unsecured remote access points. Siemens helps reduce these vulnerabilities through multilayered defense-in-depth approach across building and OT systems, hardened ex-works products and a specialized Cyber Security Response Team.

Reduced and secured attack surface

Minimize and secure exposure across converged IT/OT environments through segmentation, Zero Trust principles, and secure architecture design based on defense-in-depth (multilevel protection).

Regulatory compliance

Support security governance and assessments aligned with ISO 27001 (ISMS) and IEC 62443, including structured asset discovery, risk and vulnerability management, and penetration testing for OT environments.

Continuous monitoring and threat detection

Enable continuous monitoring of OT networks through logging, SIEM integration, and industrial cybersecurity sensors, helping detect anomalies and potential threats across converged infrastructure in real time.

Cybersecurity-by-design

Embed cybersecurity from system concept through deployment and operations. Our solutions are designed with built-in security by default, ensuring protection is active from day one across OT and building infrastructure systems.

How to get started

Whether you’re building a new data center or modernizing an existing one, Siemens supports IT/OT convergence with a structured approach from assessment to ongoing operations.

Mind the Gap... the ‘Air Gap'!

Many data center operators still isolate OT systems with an “air gap” to stay secure. Ciaran Flanagan elaborates on how we can balance connectivity and cybersecurity - and why it’s time to rethink the air gap.
