How to build IBM QRadar to effectively manage and investigate the alerts (Use Cases)

Q: What are common IBM QRadar use cases?

Common IBM QRadar use cases include detecting malware activity, unauthorized access, policy violations, insider threats, and network anomalies. It is widely used for advanced threat detection, compliance management, threat hunting, insider threat detection, cloud security, incident response, and vulnerability management.

Q: How does IBM QRadar improve threat detection?

IBM QRadar improves threat detection by centralizing logs and network data for real-time analysis. It leverages AI and machine learning for anomaly detection through UBA and NTA, correlates events using IBM X-Force threat intelligence and the MITRE ATT&CK framework, and supports automated response workflows.

Q: Can IBM QRadar reduce false positives?

Yes. IBM QRadar uses correlation and contextual analysis to reduce noise and surface high-priority, relevant security events.

Introduction

IBM QRadar, a widely adopted SIEM platform, helps organizations detect, investigate, and respond to security threats by correlating logs and network data in real time. It highlights practical IBM QRadar use cases that demonstrate how security teams can gain visibility into malicious activity, policy violations, and anomalous behavior across enterprise environments. The article focuses on how QRadar enables centralized monitoring, advanced correlation, and actionable security insights.

Key Takeaways

Event data ingestion and normalization using custom DSMs for contextual, human-readable logs.
Automatic artifact enrichment in offenses via APIs and lookup servers.
Manual artifact enrichment with right-click plug-ins and threat intelligence sources.
Custom dashboard creation for visualization, monitoring, and actionable insights.

What should I build on IBM QRadar to effectively manage and investigate the alerts? The guide for Product Managers to explore Security Use Cases.

In an age where cyber threats are widespread, it is important that organizations keep their data secure. The IBM QRadar SIEM enables SOC Professionals to accurately detect and prioritize threats across the enterprise and accelerate security operation’s processes. IBM QRadar provides Security Professionals with an actionable threat management solution for the alerts that are coming from multiple sources, such as Intrusion Detection Systems (IDS), Intrusion Prevention System (IPS), event logs and creates a Network Flow using the ingested network data.

This outlines Loginsoft’s expertise with IBM QRadar and provides some useful insights to product managers to explore the possible use cases to implement on IBM QRadar

The Possible IBM QRadar Use Cases:

Pull event data at scheduled intervals, ingest into QRadar, build custom DSM’s for event normalization and categorization from various sources and present them in a human-readable format (i.e., adding context to the events from various sources like Vendor’s Site/API/Server).
Automatic enrichment of Artifacts in Offense Summary page using vendor’s API and Lookup servers.
Manual Enrichment of Artifacts with Right-click lookup Plug-ins to enrich artifacts like IP, domain, MD5 Hash etc. using Threat Intelligence Source Provider’s API, QRadar Ariel searches and other Open-source and Premium Threat Intelligence sources.
Visualization of enriched data and providing the ability to the user for taking appropriate actions.
Provide ability to transfer offense summary page contents to Vendor Devices/API’s/Security Devices/SOAR’s.
Build Dashboards with selection criteria filters for searching any keywords in QRadar logs or in vendor data source and create widgets for displaying the results and continuous monitoring.
