proactive threat hunting
,The process of incorporating new updates and information to an organizations existing database to
improve accuracy.
Requirements (Planning & Direction) - ✔✔-This phase in the Intelligence Cycle sets out goals for the
intelligence-gathering effort.
Collection (& Processing) - ✔✔-This phase in the Intelligence Cycle uses software tools, such as SIEMs,
and then is processed for later analysis.
Analysis - ✔✔-This phase in the Intelligence Cycle is performed against the given use cases from the
planning phase and may utilize automated analysis, artificial intelligence, and machine learning.
Dissemination - ✔✔-This phase in the Intelligence Cycle refers to publishing information produced by
analysis to consumers who need to act on the insights developed.
Feedback - ✔✔-This phase in the Intelligence Cycle aims to clarify requirements and improve the
collection, analysis, and dissemination of information by reviewing current inputs and outputs.
