How QRadar works and Architecture?

Data Collection: QRadar collects log and event data from various sources, including network devices, servers, endpoints, applications, and cloud services.
Normalization and Parsing: The collected data is normalized and parsed to ensure it is in a consistent format and can be analyzed effectively.
Real-Time Analysis: QRadar analyzes incoming data in real-time using predefined and custom rules to detect security threats and anomalies.
Correlation Engine: The system’s correlation engine correlates data from multiple sources to identify patterns and prioritize incidents based on risk.
Alerting and Notifications: When a potential security incident is detected, QRadar generates alerts and notifications for security analysts to investigate.
Incident Investigation: Security analysts can use QRadar’s tools to investigate incidents, analyze historical data, and determine the root cause of security events.

QRadar Architecture:

QRadar’s architecture is typically composed of the following components:

Event Collectors: These agents collect log and event data from various sources and forward it to the QRadar Console or Event Processor.
Event Processors: Event processors parse, normalize, and analyze incoming data. They perform event correlation and generate alerts.
QRadar Console: The console provides the user interface for managing and monitoring security events. It allows security analysts to investigate incidents and configure rules and reports.
Flow Processors: Flow processors analyze network flow data, providing insights into network traffic and behavior.
Data Storage: QRadar stores normalized data and indexed data for historical analysis and reporting.
Custom Rules and Offenses: Custom rules can be defined to meet specific security requirements, and offenses are generated when rule conditions are met.
Reference Data: QRadar uses reference data, such as threat intelligence feeds and vulnerability data, to enrich and contextualize security events.
External Integrations: QRadar can integrate with external systems, such as ticketing systems, SIEM solutions, and threat intelligence feeds, to enhance its capabilities.
