Indicators are a fundamental aspect of cyber threat intelligence. You encounter indicators daily in your work and must know how to utilize them to achieve your intelligence requirements. To help you with this, let me introduce you to the indicator lifecycle.
The indicator lifecycle is a foundational model that empowers cyber security analysts to work with indicators using a structured approach. It combines people, processes, and technology to be a dynamic model applicable across many security operations. For you, as a threat intelligence analyst, it will provide a systematic method for moving between data points, investigating an intrusion, and gathering evidence – pivoting.
Let’s start by learning more about indicators so you can unlock the full potential of the indicator lifecycle!
