Set up searches for IP ranges, domains, or critical infrastructure components. Use filters to focus on actionable insights, such as identifying newly exposed services or vulnerable software versions.
Export Format Essentials
Ensure your OSINT tools export data in formats compatible with your SIEM. Once this is set, you can move on to creating stable ingestion pipelines.
Setting Up Data Ingestion Pipelines
A reliable data ingestion pipeline ensures OSINT data flows smoothly into your SIEM for real-time analysis.
Splunk Integration
Splunk Enterprise Security allows administrators to pull in threat intelligence from internet feeds, upload structured files, or directly insert data from events. Internet feeds are particularly useful for automated, continuous data updates. After setting up the feed, verify that the data is correctly parsed and that threat indicators are added to the threat intelligence collections.
QRadar Integration
QRadar automatically parses and normalizes log events using Device Support Modules (DSMs). It supports protocols like syslog, SNMP, and syslog-tcp for event collection and can establish outbound connections through SCP, SFTP, FTP, and other methods. If your OSINT tool lacks built-in support, QRadar’s Universal Cloud Rest API can help you create custom parsers or collect data from REST APIs, enabling integration with tools that provide API access.
Ensuring Pipeline Stability
To prevent disruptions, build redundancy into your pipelines. Use monitoring alerts for failures, retry mechanisms for temporary issues, and backup data sources when available. Regularly test the pipelines to catch and fix problems before they affect your security operations.
Once your pipeline is stable, the next step is to map and automate threat feeds for efficient analysis.
Mapping and Automating Threat Feeds
The final step is mapping OSINT fields to your SIEM schema and automating the processing of threat intelligence.
Field Mapping
Mapping OSINT data correctly enhances your SIEM's ability to detect threats. For instance, map Shodan’s IP address fields to your SIEM’s source IP fields or Maltego’s relationship data to correlation fields. Identify where threat intelligence data can best fit into your SIEM workflows and align these mappings with your integration goals. This structured approach allows your SIEM to automatically correlate OSINT data with internal events.
Automation Setup
Automate data ingestion using APIs or other available tools to keep your threat intelligence current. Configure rules that trigger alerts when OSINT data matches internal events. Many organizations have found that integrating threat intelligence into their SIEM reduces false positives and helps prioritize real threats.
Ongoing Monitoring
Regularly track the integration’s performance and make adjustments as needed. Monitor key metrics, such as the number of new indicators ingested daily, correlation hit rates, and changes in false positive rates.

Integrating OSINT data into your SIEM system can speed up threat detection, cut down on false positives, and provide more detailed context for incidents. The key lies in crafting effective detection rules, utilizing machine learning, and applying these tools to practical scenarios.
Creating Detection Rules and Alerts
Detection rules translate raw intelligence into actionable alerts by defining patterns and behaviors tied to threats.
"In essence, a Detection Rule defines patterns, behaviors, or indicators of compromise (IoCs) that are associated with known threats. These rules are designed to trigger alerts when the logic returns True during log monitoring." – Ryan G. Cox
Building Strong Detection Logic
Start by identifying critical OSINT fields that can trigger alerts. For instance, if Shodan reveals unauthorized exposed services, set up an alert. Similarly, analyzing relationships between entities can help uncover unusual connections that might signal a compromise.
In February 2024, a security engineer showcased this approach by creating a detection rule for AWS console logins without multi-factor authentication. By analyzing AWS CloudTrail logs, the engineer pinpointed key fields like "eventName", "consoleLogin", "mfaAuthenticated", and "mfaUsed" to distinguish secure logins from potentially risky ones. The detection rule, written in Python, was deployed with severity levels tailored to factors like account age.
Integrating Threat Intelligence
Combine OSINT feeds with detection rules to flag malicious domains or IP addresses. This approach enhances correlation and helps identify threats that might otherwise go unnoticed.
Continuous Tuning
Keep an eye on alert volumes and accuracy, adjusting thresholds as needed to reduce false positives without compromising detection. Regularly fine-tune detection rules to stay ahead of evolving threats.
With detection rules in place, machine learning can further refine your system’s threat analysis capabilities.
Using Machine Learning for Threat Analysis
Machine learning shifts OSINT-SIEM integration from reactive to proactive, enabling predictive threat identification. AI-driven analytics process large volumes of data in real time, catching anomalies that human analysts might miss.
The Impact of AI Integration
Modern AI tools detect threats 67% faster and prevent 84% more breaches compared to older systems. They also reduce breach costs by 40–60%. Considering that the average SOC analyst deals with over 11,000 alerts daily - 95% of which are false positives - machine learning helps cut through the noise by prioritizing genuine threats and contextualizing them with OSINT data.
Implementing AI-Driven Analysis
Choose platforms that provide transparency into their machine learning models, allowing your team to understand and tweak detection algorithms. OSINT data enriches these models by supplying external insights, such as details on current attack campaigns or known malicious indicators. Machine learning also assists in prioritizing vulnerabilities, ensuring your team focuses on the most critical issues.
