1. Offense AnalysisThis domain focuses on the lifecycle of an offense—from initial detection to final resolution.Triage and Initial Investigation:Navigating the Offenses tab and interpreting offense status.Identifying contributing events and flows.Analyzing offense source, destination, and associated IP addresses.Validating offenses (differentiating true positives from false positives).Evidence and Contextual Analysis:Reviewing vulnerability status and threat intelligence (e.g., X-Force Exchange).Documenting investigations with triage notes.Offense Management:Prioritizing offenses using Magnitude, Severity, Relevance, and Credibility.Assigning offenses to users and managing ownership.Implementing offense closing procedures and utilizing closing reasons.2. Rules and Building Block DesignAnalysts must understand the underlying logic that powers threat detection within QRadar.Logic Components:Understanding the structure of Rules vs. Building Blocks.Differentiating between Behavioral, Anomaly, and Threshold rules.Rule Configuration and Tuning:Analyzing rule conditions (e.g., event/flow data, regular expressions).Utilizing the Network Hierarchy to improve rule accuracy.Designing Host, Category, and Port definitions within building blocks.Operational Maintenance:Reviewing and recommending updates to rules to minimize false positives.
