Which component is NOT a primary part of IBM QRadar?

The correct answer identifies that the Data Encryptor is not a primary component of IBM QRadar. In the architecture of QRadar, the main components typically include the Flow Collector, Event Collector, and Flow Processor, all of which serve specific and essential roles in managing and analyzing security data.

The Flow Collector is responsible for capturing and managing flow data from network devices and systems, while the Event Collector gathers event data from various sources, such as logs from servers and applications. The Flow Processor analyzes flow data and collaborates with existing components to provide insights and actionable intelligence.

While data encryption is an important aspect of securing information within any SIEM solution, it is not considered a primary component of QRadar. Instead, encryption is often implemented as a security measure that might be applied during data transmission or storage but is not a standalone component that defines the core functioning of QRadar.
