Defense in Depth

360 Degrees of Protection

The convergence of software, data and connected devices, commonly referred to as the Internet of Things, brings unprecedented opportunities to industrial companies like real time operations optimization and prescriptive analytics. This sweeping technological transformation also introduces a wide array of security threats that require a layered defense approach to detect, respond and remediate at all levels of operations.

A Deeper Look at Layered Protection

To ensure comprehensive protection of production environments, all levels must be protected simultaneously, from field automation to corporate management systems. Siemens helps industrial companies build layered defenses with a comprehensive security solution that addresses the three pillars of industrial control systems: system and software integrity, network security and plant security. Our methodology:

  • Capitalizes on Siemens operational technology expertise 
  • Integrates recommendations from leading security standards (e.g. IEC 62443, RMF, ISO 27000)
  • Ensures systems integrity through integrated security features in drives, controllers, HMI systems, process automation and motion control systems
  • Protects against unauthorized network activity via encrypted communication, VPN, firewalls, cell protection, DMZ, and remote traffic monitoring via intrusion detection systems
  • Secures physical access to plant and critical components via access control and asset protection services

Network Security

Industrial Automation Meets IT Security

Security requirements for industrial control systems differ significantly from the requirements of corporate IT. Designing and implementing a secure industrial network requires core competencies in both cyber security and industrial automation. Siemens pairs depth of expertise in these disciplines with an understanding of specific customer business objectives, operating requirements, and security posture.


Armed with best practices in architecture, design and management developed across thousands of global client deployments, Siemens helps customers keep their network from becoming their weakest link.
