Networks as a security factor

Network security for industry according to cybersecurity recommendation IEC 62443

Network security to protect industrial plants

Cybersecurity is the subject that should be on the agenda of every business right now. With “Defense in Depth” as a comprehensive protection strategy, Siemens provides answers in the form of defense throughout all levels based on the recommendations of IEC 62443. Part of the Industrial Security concept is network security to protect automation networks against unauthorized access. This includes checking all interfaces, like those between office and plant networks, or checking remote accesses to the Internet, and may be carried out using firewalls or, as appropriate, by creating a protected secure zone (a ‘demilitarized zone’ or DMZ). Based on professional planning, design, and the implementation of available, powerful network infrastructures, it is possible to create comprehensive yet secure OT networks.

Defense in Depth

Secure communication in industrial networks

An approach that covers all levels simultaneously is essential to comprehensively protect industrial facilities both internally and externally – from operational to field level, from access control to copy protection. This is why we use “Defense in Depth” as our comprehensive protective strategy aligned with the recommendations of IEC 62443, the leading standard for security in industrial automation.

Know how your network is protected

Experts calculate that 25 billion communications-capable machines will be networked as part of the Industrial Internet of Things in just a few years from now. This exponentially increases the attack surface and is accompanied by new network security requirements that ensure the continued protection of machines, plants, and expertise. Industrial Security is based on a multilayered concept – “Defense in Depth” – that gives your plant both all-round and in-depth protection. It starts with conventional building access and extends to the securing of sensitive areas by means of key cards. Network security includes the protection of automation networks against unauthorized accesses with network access protection, segmentation, and encrypted communication. System integrity protects your automation systems and control components against unauthorized accesses and meets special requirements such as know-how protection.
