According to the CMMC Code of Professional Conduct (CoPC), a Certified CMMC Assessor (CCA) must act with integrity, accuracy, and objectivity. When faced with false statements from an organization's leadership, the CCA's primary duty is to the integrity of the assessment itself. The appropriate response is to document the discrepancy between the CEO's statements (interview evidence) and the verifiable, objective evidence gathered through examination and testing. The assessment findings must be based on this objective evidence. This approach ensures the final report is an accurate and impartial representation of the organization's security posture, fulfilling the CCA's ethical and professional obligations without escalating the situation unprofessionally or ignoring critical information.

B. Ignoring false statements is a dereliction of duty and violates the CoPC's tenets of accuracy and objectivity, compromising the assessment's integrity.
C. "Perjury" is a legal term for lying under oath; a CMMC assessment is not a legal proceeding. This action is an inaccurate and inappropriate escalation.
D. Confronting the CEO is unprofessional and adversarial. The CCA's role is to assess objectively, not to interrogate or create a hostile environment.

1. Cyber AB Code of Professional Conduct (CoPC), Version 2.2, Canon 1: "Certified Professionals shall: 1.1 Act with integrity, accuracy, and objectivity in the performance of their duties." This canon directly supports documenting facts as they are found (accuracy) and not being swayed by false statements (objectivity). The CCA's duty is to the factual report.

2. CMMC Assessment Process (CAP) for CMMC Level 2, Version 2.0, Section 2.4, Assessment Tenets: This section states, "Assessors shall remain independent and objective in their assessment activities... Assessment results shall be based on sufficient, relevant, and reliable evidence." This requires the assessor to prioritize reliable evidence over statements that are proven false and to document the basis for their conclusions.

3. CMMC Assessment Process (CAP) for CMMC Level 2, Version 2.0, Section 3.3.3, Collect Objective Evidence: This section details the three methods for gathering evidence: Examine, Interview, and Test. It establishes that findings must be supported by objective evidence. A false statement is interview evidence that would be outweighed and contradicted by conflicting evidence from the "Examine" or "Test" methods, which the assessor must document.
