How can DMARC RUF reports support incident response?

DMARC forensic reports (RUF) provide details about specific authentication failures. During incidents, they reveal: exact messages failing authentication, headers showing attack patterns, and timing information for investigation.

Incident response value: RUF reports can show **spoofing** campaign details, help identify attack infrastructure, and provide evidence for reporting. They complement aggregate reports with specific message data.

Limitations: not all receivers send RUF, privacy concerns limit content included, and high volume generates overwhelming data. Use RUF selectively for investigation rather than routine monitoring.
