Cybersecurity for industry: combine the real and digital worlds securely

The document presents Siemens’ integrated approach to industrial cybersecurity, enabling organizations to securely combine the real and digital worlds. At its core is the Defense‑in‑Depth concept, a multi‑layered security framework that protects industrial plants across all levels—from plant management to field devices—based on internationally recognized IEC 62443 standards.

It highlights three key pillars: plant security, network security, and system integrity. These ensure protection against unauthorized access, cyberattacks, and data manipulation through measures such as access control, network segmentation, encrypted communication, and system hardening.

In addition, Siemens industrial cybersecurity services provide end‑to‑end support, including risk assessments, secure IT/OT integration, continuous monitoring, and vulnerability management. Together with Siemens Xcelerator, this enables scalable, compliant, and future‑proof cybersecurity for industrial operations and digital transformation.
