The certification is based on the standard IEC 62443-2-4 and IEC 62443-3-3 for system integrators, and IEC 62443-4-1 and IEC 62443-3-3 for manufacturers. TÜV SÜD is accredited according to IEC 62443 by the German Accreditation Body (DAkkS).
Automation and control system services & products could not be certified for IT security until now. Before IEC 62443, no valid international standards had been developed for this purpose. With the introduction of IEC 62443 family of standards, this situation has been changed and a certification of IACS according to IEC 62443 is now possible.
As one of the first providers, TÜV SÜD offers relevant tests and certifications according to IEC 62443. The product certification is based on the IEC 62443-4-1 standard whereby the IT security functions of the products are assessed according to IEC 62443-3-3. For system integrators, the certification is done according to standard IEC 62443-2-4 and the IT security functions are also evaluated according to IEC 62443-3-3.
