How does QRadar handle data normalization?

QRadar handles data normalization by converting data into a common format. This process is essential for ensuring that data from various sources can be correlated and analyzed effectively. Different systems may generate logs and events in unique formats, using different terminology and structures to represent the same information. By normalizing this data, QRadar allows for a unified view and makes it easier to conduct comprehensive threat analysis, develop security insights, and create meaningful reports.

Normalization facilitates the comparison and correlation of events across diverse sources, enabling security teams to identify patterns and detect anomalies more effectively. This process also aids in the application of rules and the development of use cases because it ensures that all data adheres to a standard structure and definition, which is crucial for accurate incident response and threat detection.

While data normalization occurs alongside other data handling processes, such as managing relevance and eliminating duplicates, the primary goal is to prepare the data by creating consistency across all incoming datasets. This is vital for the analysis performed by QRadar's analytics and monitoring tools.
