The Cyber AB (formerly CMMC-AB) Code of Professional Conduct (CoPC) is a mandatory agreement that all CMMC ecosystem members---including Certified CMMC Professionals (CCPs) and Certified CMMC Assessors (CCAs)---must adhere to. This code ensures the reliability and trustworthiness of the assessment process.

The fundamental principles that form the foundation of the CoPC include:

Responsibility: This refers to the obligation of the CMMC professional to act in the best interest of the CMMC program, the Department of Defense (DoD), and the public. It includes maintaining professional competence and performing duties with due care.

Confidentiality: Assessors and professionals are granted access to sensitive information, including Controlled Unclassified Information (CUI) and proprietary business data of the Organization Seeking Certification (OSC). They must ensure this information is protected from unauthorized disclosure.

Information Integrity: This principle requires that all data, findings, and reports generated during the assessment are accurate, complete, and have not been tampered with. It ensures that the 'Met' or 'Not Met' determinations are based on honest evidence.

Why other options are incorrect:

Options A and B (Objectivity): While 'Objectivity' is a crucialbehavioralrequirement for an assessor (remaining unbiased), the specific high-level triad often emphasized in the CMMC Professional training and the formal CoPC documentation focuses on the Responsibility-Confidentiality-Integrity framework to align with standard professional ethics and information security pillars.

Options A and C (Classification): 'Classification' is a process used for National Security Information (Classified info), whereas CMMC is primarily focused on unclassified information (CUI and FCI). Classification is not a core principle of the professional code of conduct.

Options A and C (Information Accuracy): While accuracy is vital, it is considered a subset of Information Integrity within the formal definitions provided in the CCP curriculum.
