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 manufactures. TÜV SÜD is accredited according to IEC 62443 by the German Accreditation Body (DAkkS).
Automation and control system services and products could not have been certified regarding IT security until now. No international valid standards had been developed for this purpose. This situation has changed with the publication of valid documents of IEC 63443 family of standards, so that 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.
