Summary
In this chapter, we covered the definitions of cyber threat intelligence (CTI) and advanced persistent threats (APTs). We reviewed each of the steps involved in the intelligence cycle and provided an overview of how to carry out data collection and processing. Finally, we closed this chapter by looking at one of the main challenges that intelligence analysts face: analyst bias.
In the next chapter, we will introduce the concept of threat hunting and the different methodologies and approaches we can follow.
