SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires splunk-sdk, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This skill enables security teams to analyze and investigate incidents by collecting, correlating, and visualizing logs from Windows Event Logs, Sysmon, proxy, DNS, and firewall sources using Splunk SPL and CIM data models.

Core Features & Use Cases

Centralized incident investigation across multiple data sources using Splunk SPL and CIM normalization
Build detection logic and incident timelines, then convert findings into actionable insights for SOC plays
Create persistent correlation rules and notable events within Splunk ES to accelerate incident response

Quick Start

Ingest the relevant logs into Splunk, run the included SPL queries, and review the incident timeline to validate findings.

FAQPage Schema

How do I investigate security incidents using Splunk SPL and CIM data models?▼

Investigate security incidents using Splunk SPL by extracting, correlating, and visualizing logs from Windows Event Logs, Syslog, proxy, DNS, and firewall sources normalized through CIM data models.

Do I need Splunk Enterprise Security installed to analyze logs with Splunk SPL?▼

Yes, analyzing logs with this Skill requires Splunk Enterprise Security, CIM data models, and moderate SPL proficiency to normalize data and create persistent correlation rules and notable events.

How do I build incident timelines and detection logic from Windows Event Logs and Sysmon in Splunk?▼

Build incident timelines and detection logic by running included SPL queries against ingested Windows Event Logs and Sysmon data to validate findings and convert them into actionable SOC insights.

What is the best way to create persistent correlation rules and notable events in Splunk ES?▼

Create persistent correlation rules and notable events in Splunk ES by leveraging CIM-aligned data models to accelerate incident response and centralize investigations across multiple security data sources.

Can I use Splunk SPL to correlate proxy, DNS, and firewall logs for incident response?▼

Yes, you can use Splunk SPL to correlate proxy, DNS, and firewall logs during incident response by applying CIM normalization to centralize and visualize investigative findings across diverse sources.

What are the limitations of analyzing security logs in Splunk without CIM data models?▼

Without CIM data models, Splunk SPL investigations lack normalized data structures, preventing the creation of persistent correlation rules and notable events necessary for accelerated incident response workflows.
