What the documentation says
Technical documentation and research consistently highlight DMARC's role as an email authentication protocol and the importance of processing its reports. They detail how aggregate (RUA) reports provide XML data on email streams, which can be parsed and visualized to reveal compliance and potential threats. Open-source projects often serve as reference implementations for this parsing and visualization. For a general understanding, explore a simple guide to DMARC, SPF, and DKIM. Understanding the list of DMARC tags and their meanings is also beneficial.
Key findings
- Report types: DMARC generates aggregate (RUA) and forensic (RUF) reports.
- XML format: Aggregate reports are typically in XML, requiring parsing for readability.
- Visualization: Tools are necessary to transform raw XML into graphical representations for analysis.
- Data storage: Processed DMARC data is often stored in databases like Elasticsearch.
Key considerations
- Standard compliance: Adherence to DMARC standards (RFC 7489) is crucial for accurate reporting.
- Parser reliability: The DMARC report parser must correctly interpret various report structures.
- Data security: When self-hosting, ensure secure storage and access to sensitive DMARC data.
- Resource demands: Analyzing large volumes of DMARC data can be resource-intensive. Debricked's blog offers a guide on how to analyze and visualize DMARC reports.
