A Splunk administrator needs to integrate a third-party vulnerability management tool to automate remediation workflows.

Why Use REST APIs for Integration?

When integrating a third-party vulnerability management tool (e.g., Tenable, Qualys, Rapid7) with Splunk SOAR, using REST APIs is the most efficient and scalable approach.

????Why REST APIs?

APIs enable direct communication between Splunk SOAR and the third-party tool.

Allows automated ingestion of vulnerability data into Splunk.

Supports automated remediation workflows (e.g., patch deployment, firewall rule updates).

Reduces manual work by allowing Splunk SOAR to pull real-time data from the vulnerability tool.

Steps to Integrate a Third-Party Vulnerability Tool with Splunk SOAR Using REST API:

1️⃣Obtain API Credentials – Get API keys or authentication tokens from the vulnerability management tool.2️⃣Configure REST API Integration – Use Splunk SOAR’s built-in API connectors or create a custom REST API call.3️⃣Ingest Vulnerability Data into Splunk – Map API responses to Splunk ES correlation searches.4️⃣Automate Remediation Playbooks – Build Splunk SOAR playbooks to:

Automatically open tickets for critical vulnerabilities.

Trigger patches or firewall rules for high-risk vulnerabilities.

Notify SOC analysts when a high-risk vulnerability is detected on a critical asset.

Example Use Case in Splunk SOAR:

????Scenario: The company uses Tenable.io for vulnerability management.✅Splunk SOAR connects to Tenable’s API and pulls vulnerability scan results.✅If a critical vulnerability is found on a production server, Splunk SOAR:

Automatically creates a ServiceNow ticket for remediation.

Triggers a patching script to fix the vulnerability.

Updates Splunk ES dashboards for tracking.

Why Not the Other Options?

❌A. Set up a manual alerting system for vulnerabilities – Manual alerting is inefficient and doesn’t scale well.❌C. Write a correlation search for each vulnerability type – This would create too many rules; API integration allows real-time updates from the vulnerability tool.❌D. Configure custom dashboards to monitor vulnerabilities – Dashboards provide visibility but don’t automate remediation.
