What Threat Intelligence Is and Why It Matters

This lesson defines cyber threat intelligence as evidence-based knowledge about adversaries, their motivations, capabilities, infrastructure, and likely actions. It distinguishes intelligence from raw data, alerts, news, and indicators, then shows how CTI helps security teams make better decisions.

Learners will see why threat intelligence matters across strategic, operational, and tactical security work, and how it supports prioritisation, detection, incident response, risk conversations, and security planning. The lesson sets a practical foundation for later work on collection, analysis, frameworks, reporting, and operationalisation.
