IR-9Information Spillage Response
Respond to information spills by: Assigning {{ insert: param, ir-09_odp.01 }} with responsibility for responding to information spills; Identifying the specific information involved in the system contamination; Alerting {{ insert: param, ir-09_odp.02 }} of the information spill using a method of communication not associated with the spill; Isolating the contaminated system or system component; Eradicating the information from the contaminated system or component; Identifying other systems or system components that may have been subsequently contaminated; and Performing the following additional actions: {{ insert: param, ir-09_odp.03 }}.

Weaknesses this control addresses (6)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+ | The control's identification, isolation, alerting, and eradication steps directly limit the impact and exploitation window of unauthorized sensitive information exposure. |
CWE-532 | Insertion of Sensitive Information into Log File | 1,400+ | The process of identifying and eradicating spilled information applies directly to sensitive data inserted into log files. |
CWE-212 | Improper Removal of Sensitive Information Before Storage or Transfer | 100+ | Eradication of spilled information from contaminated systems mitigates the effects of improper removal of sensitive data before storage or transfer. |
CWE-538 | Insertion of Sensitive Information into Externally-Accessible File or Directory | 98 | Isolation and eradication reduce the ability to exploit sensitive information inserted into externally-accessible files or directories. |
CWE-226 | Sensitive Information in Resource Not Removed Before Reuse | 36 | The eradication and cross-system identification steps ensure sensitive information is removed before resources are reused or further accessed. |
CWE-540 | Inclusion of Sensitive Information in Source Code | 31 | Detection and removal of spilled information addresses cases where sensitive data was included in source code. |
