PM-21Accounting of Disclosures
Develop and maintain an accurate accounting of disclosures of personally identifiable information, including: Date, nature, and purpose of each disclosure; and Name and address, or other contact information of the individual or organization to which the disclosure was made; Retain the accounting of disclosures for the length of the time the personally identifiable information is maintained or five years after the disclosure is made, whichever is longer; and Make the accounting of disclosures available to the individual to whom the personally identifiable information relates upon request.

Weaknesses this control addresses (5)AI-assisted
CWEs ranked by how often they appear in real CVEs. The rationale describes how this control reduces exploitability of each weakness class.
| CWE | Name | CVEs | Why this control addresses it |
|---|---|---|---|
CWE-200 | Exposure of Sensitive Information to an Unauthorized Actor | 11,000+ | Requiring detailed, requestable records of every PII disclosure directly aids detection of unauthorized exposures of sensitive information. |
CWE-862 | Missing Authorization | 10,200+ | Organizations must be able to justify every disclosure, which makes missing authorization for data release both detectable and operationally costly. |
CWE-284 | Improper Access Control | 6,900+ | Accurate accounting of disclosures presupposes and thereby incentivizes proper access-control enforcement; gaps become visible when individuals review their records. |
CWE-359 | Exposure of Private Personal Information to an Unauthorized Actor | 200+ | The control mandates an auditable trail specifically for private personal information, making unauthorized disclosures of PII more readily discoverable by the affected individual. |
CWE-778 | Insufficient Logging | 28 | Mandating retention and availability of disclosure accounting ensures security-relevant events involving PII release are logged rather than omitted. |
