Under NIST SP 800-171, Personnel Security (PS) family, requirement PS.L2-3.9.1, organizations must screen individuals prior to granting access to CUI. The screening is intended to evaluate conduct, integrity, and loyalty to ensure that individuals can be trusted with sensitive information.

Supporting Extracts from Official Content:

NIST SP 800-171 Rev. 2, PS.L2-3.9.1: “Screen individuals prior to authorizing access to organizational systems containing CUI… Screening is intended to assess an individual’s conduct, integrity, judgment, loyalty, and reliability.”

CMMC Level 2 Assessment Guide (Personnel Security practices): confirms that screening covers conduct, integrity, and loyalty.

Why Option C is Correct:

The key attributes explicitly listed are conduct, integrity, and loyalty.

Options A and B describe subjective or informal measures, not compliance criteria.

Option D uses terms not aligned with the official requirement.
