Parsing Failure: A JSON parser error implies QRadar couldn't correctly extract structured data from the raw log messages created by the custom extension.

Fallback - CRE: QRadar defaults to storing unparseable events as CRE, preserving the raw log message but losing structured fields.

Troubleshooting: CRE events indicate the need to fix the log source extension's JSON parsing.

Common Rules: The foundation of QRadar's event analysis. They operate on structured events representing activity from various log sources.

Event Processor: Responsible for normalizing and categorizing raw log data from various sources into structured QRadar events.

Here's why this is the most effective approach:

False Positive Reduction: The goal is to stop legitimate traffic from triggering offenses. This requires fine-tuning the rules generating those offenses.

Building Blocks: Rules are housed within building blocks in QRadar's hierarchical rule structure. The Custom Rules Editor is the tool to modify them.

Event-Based Tuning: The optimal approach is to target the specific event that's causing the false positives, making the solution more precise.
