TÜV NORD carries out world’s first Maturity Level 4 certification

TÜV NORD has carried out the world’s first Maturity Level 4 certification in the IECEE scheme in the Industrial Cyber Security (CYBR) category. This testifies to the achievement by Siemens AG’s “Lean Product Lifecycle @ SI EA” system of the highest level of process maturity. This places both Siemens and TÜV NORD at the forefront of certification activities in the globally established IECEE scheme.

"We congratulate Siemens on its terrific achievement and are pleased to have been able to make qualified use of our technical know-how and the IT expertise of our sister company TÜVIT,” says Matthias Springer, Cluster Manager for Functional Safety & Security at TÜV NORD. TÜV NORD is one of the few providers on the international market to have been accredited by both the German accreditation body (DAkkS) and the international standardisation organisation, the IECEE, to carry out all relevant validations and certifications pursuant to IEC 62443.

IEC 62443-4-1 is part of a family of standards whose goal is to ensure IT security for industrial automation systems. Companies that use networked components, be they in the control systems for an industrial plant, the control of railway vehicles or the protection technology used in an electricity substation, must protect their communications networks from cyber attacks – and that protection must be verifiable. This is assured by means of the analysis and evaluation of security concepts, measures and product development processes. This process was successfully certified by TÜV NORD at  Siemens Smart Infrastructure, Electrification & Automotion (SI EA).

In the case of Siemens Smart Infrastructure, Electrification & Automation, Level 4 certification means that all organisational processes are mapped at business unit level and components are developed and designed at the highest level of quality, i.e. with continuous improvement processes and measurable quality goals – along the entire development life cycle. 

The IEC 62443 series of standards currently comprises eleven sub-standards. These cover the areas of organisation/processes, system and components alongside procedural and functional requirements. IEC 62443 thus covers the entire industrial spectrum and meets the requirements of operators, integrators and manufacturers alike.
