THREAT HUNTING VS. THREAT INTELLIGENCE

Summary from the TLDR InfoSec newsletter

Threat intelligence focuses on understanding the external threat landscape, while threat hunting proactively investigates internal systems for threats that have evaded automated defenses through hypothesis-driven analysis and behavioral anomaly detection. The two functions create a feedback loop: intelligence provides IOCs, TTPs, and focus areas to guide hunting hypotheses, while hunting discoveries enrich intelligence with validated internal findings. Security teams should integrate both by using threat intelligence to prioritize hunting efforts via MITRE ATT&CK TTP mapping, embedding intelligence feeds into SIEM/EDR for automated IOC correlation, and establishing workflows that link hunting results to strategic and tactical intelligence products.
