Integrating OpManager with SIEM tools

IT teams must sift through thousands of log entries every minute they monitor firewall alerts, configuration changes, and performance metrics to find genuine threats or operational issues in larger enterprises. Manual analysis is no longer viable; organizations need automated, real-time log correlation and analytics or risk catastrophic gaps in visibility and response.

Consider the 2018 healthcare data breach in Singapore: One of Singapore’s largest healthcare providers suffered the country’s most serious personal data breach when attackers exfiltrated 1.5 million patient records over nine days without detection. A Committee of Inquiry later found:

• Bulk data dump queries against the Patient Care Database went unnoticed from June 26 to July 4 because there were no SIEM correlation rules or real-time alerts in place.
• The high volume of records accessed never triggered alarms, as logs remained siloed.
• Database logs weren’t tied to other security streams, such as firewall events or authentication logs, leaving security teams without a holistic view.

The breach caused severe reputational damage, regulatory scrutiny, and triggered a nationwide overhaul of Singapore’s public sector cybersecurity practices.

This incident underscores a critical lesson: Centralized SIEM correlation transforms raw log data into actionable intelligence, stopping short-lived intrusions from becoming prolonged, high-impact breaches. Had OpManager, or any network monitoring tool, forwarded audit and access logs to a SIEM platform, the abnormal query patterns could have been detected and flagged early.

Early threat detection with OpManager-SIEM integration

When integrated with a SIEM platform, OpManager can help detect and act on early warning signs of potential breaches before they escalate into major incidents.

• Real-time anomaly detection: OpManager’s access and audit logs would have captured unusual spikes in database access and query volume. These logs, when forwarded to a SIEM solution, could trigger alerts based on abnormal behavioral patterns.
• Event correlation across systems: A SIEM tool would have correlated the sudden database activity with other events, such as off-hours logins, failed access attempts, or firewall traffic anomalies, connecting the dots early in the attack sequence.
• Automated alerting and escalation: As soon as thresholds were breached (e.g., excessive data reads or unknown IP access), the SIEM platform could have triggered an automated alert or workflow.



• Centralized visibility for faster investigation: With OpManager feeding access and audit logs into a SIEM dashboard, the security team would have had a unified view of infrastructure behavior, reducing the time to detect, investigate, and respond to abnormal activities.
• Historical baselines and machine learning: Leveraging historical performance baselines from OpManager, the SIEM solution’s machine learning capabilities could have identified the data access patterns as an anomaly, even if they initially mimicked legitimate usage.

Integrating OpManager with your SIEM platform bridges the gap between network monitoring and security intelligence, enabling early detection, swift mitigation, and complete visibility.

OpManager's seamless integration with Splunk

While OpManager can integrate with a range of SIEM tools, Splunk is a popular choice among enterprises due to its strong data processing and visualization capabilities. Let’s take a closer look at how OpManager and Splunk work together to enhance security and operational efficiency.

OpManager seamlessly integrates with Splunk, forwarding logs, including syslogs, SNMP traps, access logs, and audit trails from routers, switches, firewalls, servers, and other devices for centralized indexing, correlation, and analysis.

Unified visibility: Splunk’s dashboards enable teams to visualize performance trends or anomalies in real time during outages or attacks. Security events from OpManager, such as unauthorized logins or configuration changes, can be correlated with other security data to reveal complex attack patterns.

Simplified compliance reporting: OpManager’s audit logs show exactly who changed what and when. When these logs are ingested into Splunk, compliance teams can generate reports for standards like HIPAA, the PCI DSS, or ISO 27001, without combing through raw data.

Automated workflows with Splunk's SOAR: When OpManager detects a critical event (e.g., high CPU usage or suspicious login behavior), Splunk can trigger SOAR workflows, such as alerting the SOC, creating a ticket, or executing a remediation script.

By integrating OpManager with a SIEM platform like Splunk, IBM QRadar, or LogRhythm, you gain real-time threat detection, smarter incident response, and complete control over your IT infrastructure. Start turning raw logs into meaningful insights, strengthen your defenses, stay audit-ready, and resolve issues before they impact operations.
