SER-012 — Correlation & Canonical Understanding
**Correlation as decision support**—how organizations link isolated observations into **canonical understanding** with relationship context, and use that understanding in prioritization, investigation, risk, and communication. **Not** entity resolution algorithms, graph database administration, or platform implementation documentation.
SER-012 — Correlation & Canonical Understanding
Series: SER-012
Volume: VOL-004 Security Operations
Version: 1.0

Prerequisite: SER-011 Exposure Management (minimum: KID-CON-0119); Volume 1 seed KID-CON-0009 recommended
Purpose
Correlation as decision support—how organizations link isolated observations into canonical understanding with relationship context, and use that understanding in prioritization, investigation, risk, and communication. Not entity resolution algorithms, graph database administration, or platform implementation documentation.
Educational flow: Volumes 1–3 (analytical + intelligence + entity foundations) → SER-011 (exposure) → How operations build linked understanding from fragments
Authority anchors: KID-GLS-0013, KID-GLS-0038, KID-GLS-0039, KID-GLS-0012, KID-ARC-0001
Volume 4 pattern: Every article closes with Why this matters for security decisions.
