Guidelines 4/2018 on the accreditation of certification bodies under Article 43 of GDPR
SECTION 8 MANAGEMENT SYSTEM REQUIREMENTS
A general requirement of the management system according to chapter 8 of ISO/IEC 17065/2012 is that the implementation of all requirements from the previous chapters within the scope of the application of the certification mechanism by the accredited certification body is documented, evaluated,controlled and monitored independently.
The basic principle of management is to define a system according to which its goals are set effectively and efficiently, specifically: the implementation of the certification services – by means of suitable specifications. This requires transparency and verifiability of the implementation of the accreditation requirements by the certification body and its permanent compliance.
To this end, the management system must specify a methodology for achieving and controlling these requirements in compliance with data protection regulations and for continuously checking them with the accredited body itself.
These management principles and their documented implementation must be transparent and be disclosed by the accredited certification body pursuant in the accreditation procedure pursuant to Article 58 and thereafter at the request of the data protection supervisory authority at any time during an investigation in the form of data protection reviews pursuant to Art. 58(1)(b) or a review of the certifications issued in accordance with Article 42(7) pursuant to Article 58(1)(c).
In particular, the accredited certification body must make public permanently and continuously which certifications were carried out on which basis (or certification mechanisms or schemes), how long the certifications are valid under which framework and conditions (recital 100).
