Summary

Threat intelligence should be pragmatic and actionable. Its evidence-based nature has made it valuable for many security use cases: SOC, IR, vulnerability management, risk analysis, fraud detection and prevention, and threat hunting. In this chapter, we have looked at how threat intelligence empowers SOC by enhancing SIEM capabilities. We have discussed SIEM architecture and its use case for reactive and proactive defense. We then discussed two use cases of intelligence (SOC and IR), describing how it addresses the SOC and IR challenges. And finally, we reviewed the benefits of integrating intelligence into SIEM.

IOCs and the pyramid of pain have been briefly discussed in previous chapters. In the next chapter, we dig deeper into threat intelligence metrics, indicators of compromise, and the pyramid of pain. We discuss how CTI analysts can use them for CTI analysis.
