TIFCE: Threat Intelligence Feed Evaluation (+ KQL Detections)

This article introduces the TIFCE (Threat Intelligence Feed Content Evaluation) framework with KQL detections to assess and operationalize threat intelligence feeds by measuring IOC uniqueness, real-world matches, confirmed maliciousness, and ongoing feed activity. It provides reusable KQL examples for file hash, URL, and domain-based detections, guidance on centralizing multiple feeds into a single detection pipeline, and practical steps for adding new sources while reducing duplication and false positives.
