This article provides an in-depth look at effective Threat Hunting strategies, including various types of hunts (Intel Driven, Hypothesis Driven, and Data Driven) and their respective execution cadences. It emphasizes the importance of transitioning from hunt queries to detection queries and evaluating the findings to enhance security measures against potential threats.
Keypoints :
- Threat Hunting is the proactive detection of threats that evade existing security technologies.
- Effective Threat Hunting involves three main types of hunts: Intel Driven, Hypothesis Driven, and Data Driven.
- Intel Driven hunts leverage intelligence from various sources, including advisories and reports.
- Hypothesis Driven hunts apply the Scientific Method to form and test hypotheses about potential threats.
- Data Driven hunts analyze large datasets to identify anomalies that may indicate suspicious activity.
- Different hunts are executed at varying cadences: Ad-Hoc (Intel Driven), Planned (Hypothesis Driven), and Scheduled (Data Driven).
- Overlap exists between different hunt types, allowing data-driven insights to inform targeted hypothesis-driven investigations.
- The main objective is to identify evaded threats, document findings, and convert hunt queries into continuous detection mechanisms.
- Findings can reveal elements such as security posture, misconfigurations, and policy violations, enhancing overall security strategies.
- Hunt queries evolve into detection queries to ensure ongoing monitoring of suspicious activities.
- Key takeaways include what to hunt, when to hunt, and how to effectively implement and track hunts.
