Threat Intelligence (TI) is the process of collecting, analyzing, and applying knowledge about potential and active cyber threats. This knowledge helps defenders detect, prevent, and respond to attacks more effectively / especially from sophisticated actors like APTs, criminal groups, or state-sponsored campaigns.

It’s not just about knowing what happened it’s about understanding who did it, why, how, and what to do next.

From Raw Data to Intelligence

Most threat intel starts as messy, disconnected information - IPs, URLs, logs, or file hashes. That raw data is only valuable when it’s processed, contextualized, and tied to a threat scenario.

• Raw Data: One piece of info (e.g., 45.77.33.9 made 1000 SSH attempts)
• Processed Info: That IP is part of a known brute-force botnet
• Intelligence: The same botnet recently targeted your industry; you’re likely on a scan list. Add firewall rules and monitor credentials.

                             This transformation is the core of cyber threat intelligence.

The Threat Intelligence Lifecycle

1- Direction

Define the goals. What should we focus on? Is the priority actor tracking, vulnerability analysis, brand monitoring, or phishing IOCs?

2- Collection

Gather raw data from relevant sources:

• OSINT (forums, GitHub, social media)
• Threat feeds (free or paid)
• Dark web monitoring
