Certified systems for the water industry
Since April 2020, Siemens – as one of the first system and solution providers – has been providing reference architectures (blueprints), which are tailored specifically to the needs of the water/waste water/desalination industry. These blueprints and the corresponding documentation for the secure configuration of process control system and communication were certified to IEC 62443-3-3 for the first time in April 2020 by TÜV-Süd. The documents, which are available both to the Siemens project teams and to system integrators, provide a solid basis for a cyber security concept and enable low-cost and low-risk adaptations in order to meet customer-specific requirements. Siemens therefore helps the operators of critical infrastructures to reach appropriate security levels for their plants that meet national standards – e.g. B3S WA and BSI Manual for Basic IT Security, which takes into account international standard IEC 6244. The security functions are an important part of the Simatic PCS 7 process control system, which was certified to IEC 62443-3-3 in 2016, and which includes the Scalance portfolio with routers, switches and firewalls. On this basis, the blueprints offer Defense in Depth for plant security, network security and system integrity, covering all relevant functions from the field level through control rooms and remote control technology to comprehensive network management.
