As a CCA, John feels he can make some extra cash by aggregating and rewriting CMMC materials into a book titledAcing Your CMMC Assessment: A Complete Guide. You ask him about potential issues, such as the failure to get permission from the Cyber Accreditation Body. John tells you that since he is a CCA, this is not a requirement, and in any case, the information is already publicly available. Has John broken any CoPC guiding principles or practices? If so, which one?
