CONCEPT MODELS

See the lesson as a system

Use these visual guides to connect the key ideas before answering the questions.

Connect the roles in SIEM Concepts and SearchKeep data ingestion, parsing and fields, search question, and correlation rule as separate roles.
Connect the roles in SIEM Concepts and SearchA topic-specific model connects four distinct roles used to reason about siem concepts and search.
Ingestion processProcess moves event sources into central search
Event tableTable maps raw values into searchable fields
Search resourceResource turns a hypothesis into filters
Detection signalSignal combines events into reviewable behavior
Verify Result ValidationConnect result validation with its topic-specific inspection, expected outcome, and safety boundary.
Verify Result ValidationA verification model for siem concepts and search connects the final decision to evidence, outcome, and a protected boundary.
