What is the process of informing a person their need-to-know for access is terminated?

• A. Debriefing
• B. Declassification
• C. Data Spill
• D. Damage Assessment

Answer: (A)

Debriefing is the formal process of informing a person that their need-to-know for access has been terminated. When someone no longer requires access to sensitive information—whether they’ve changed roles, transferred, or left the organization—their authorization must be revoked and they need to be alerted to this change. Debriefing accomplishes several things at once: it officially notifies them that they no longer have access, it reinforces ongoing confidentiality obligations, and it handles practical steps like returning credentials or devices. In some cases it also includes a brief review of what information they were exposed to and instructions on reporting any inadvertent disclosures, ensuring no further dissemination occurs and that there’s a documented record of revocation.

Declassification would pertain to changing the classification level of information itself, not notifying or revoking an individual’s access. A data spill refers to an actual leakage of data, not the administrative action of ending access. A damage assessment evaluates the impact of an incident after it occurs, not the termination of someone’s need-to-know.
