In my previous blog, I covered the many different types of cyber threat intelligence and why gathering CTI is beneficial to security teams. In this post, I will dig into the cyber threat intelligence lifecycle framework and a model to help correlate and contextualize your findings.
Cyber threat intelligence lifecycle
Performing cyber threat intelligence gathering should be approached with a method in mind. This is where the CTI lifecycle can help provide a framework for how to accomplish CTI. Similar to the scientific method, CTI can be broken into six phases, each with a specific goal to enhance either the CTI process or the information gathered while performing CTI.
- Planning – Set requirements, goals, and methods for intelligence gathering to answer a specific question.
- Collection – The process of gathering information from sources.
- Processing – Organizing information gathered in the Collection
