To effectively manage data visibility in QRadar, which concept is fundamentally used?

In the context of IBM QRadar and data visibility management, the concept that is fundamentally used is classification. Classification involves categorizing data based on various attributes, such as sensitivity and relevance to security. By classifying data, QRadar can apply appropriate security measures and prioritize monitoring efforts based on the classification level assigned to different data sets.

This process allows security teams to focus on the most critical data, ensuring that high-risk information is adequately protected and monitored for potential threats. Additionally, classification enhances the overall efficiency of security event management by enabling more targeted analysis and response strategies, ultimately contributing to better visibility and management of security data.

Obfuscation, encryption, and segmentation, while important in their own rights, do not directly address the need for visibility as effectively as classification does. Obfuscation hides data to protect it from unauthorized access, encryption secures data in transit and at rest, and segmentation organizes network components to limit access and movement within the network. However, none of these concepts directly enhances the ability to manage and visualize data in the way that classification does.
