Requirements NIST SOURCE

Provide incident response training on how to identify and respond to a breach, including the organization’s process for reporting a breach.

Discussion (NIST Supplemental Guidance)

For federal agencies, an incident that involves personally identifiable information is considered a breach. A breach results in the loss of control, compromise, unauthorized disclosure, unauthorized acquisition, or a similar occurrence where a person other than an authorized user accesses or potentially accesses personally identifiable information or an authorized user accesses or potentially accesses such information for other than authorized purposes. The incident response training emphasizes the obligation of individuals to report both confirmed and suspected breaches involving information in any medium or form, including paper, oral, and electronic. Incident response training includes tabletop exercises that simulate a breach. See IR-2(1).

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for IR-2(3). This section is architected to display, per product: STIG ID, Finding ID, Severity, Title, Description, Check, Fix, CCI, and NIST control mapping — but nothing is populated here until a real DISA STIG/CCI dataset is ingested.
