SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires sigma, and includes scripts (resource) components.

What problem does it solve?

SOC teams frequently need portable detection rules that work across multiple SIEM platforms without vendor lock-in, enabling consistent threat coverage and shared workflows.

Core Features & Use Cases

Portable Sigma rules that can be converted to Splunk SPL, Elastic Lucene, and Microsoft Sentinel KQL.
MITRE ATT&CK mapping integration and CI/CD-ready rule validation and deployment workflows.
Use cases include standardizing detections from threat intel, migrating rules across platforms, and promoting hunting queries across systems.

Quick Start

Run the agent against your Sigma rules directory to generate Splunk-ready queries.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema

How do I convert Sigma detection rules to Splunk SPL and Microsoft Sentinel KQL?▼

You can convert Sigma detection rules to Splunk SPL and Sentinel KQL by running an automated translation script against your Sigma rules directory using pySigma and the appropriate backend plugins.

Can I integrate Sigma rule validation and deployment into a CI/CD pipeline?▼

Yes, Sigma rule validation and deployment workflows are CI/CD-ready, allowing SOC teams to automate cross-platform translation and standardize threat detections across multiple SIEM backends.

Do I need Python and pySigma to translate Sigma rules for multiple SIEM platforms?▼

Yes, you need Python 3.8 or higher with pySigma and the appropriate backends installed to automate cross-platform translation of Sigma rules into SIEM queries.

What is the best way to standardize threat detections from threat intel across different SIEMs?▼

The best way to standardize threat detections across different SIEMs is using portable Sigma rules with MITRE ATT&CK mapping, which translate seamlessly into platform-specific queries like Splunk SPL.

Does Sigma rule translation support mapping detections to MITRE ATT&CK techniques?▼

Yes, Sigma rule translation supports MITRE ATT&CK mapping integration, enabling SOC teams to maintain consistent threat coverage and standardized detection contexts across SIEM platforms.

What are the limitations when migrating Sigma rules across Elastic, Splunk, and Sentinel?▼

Limitations when migrating Sigma rules across Elastic, Splunk, and Sentinel depend on the installed pySigma backends, requiring a structured directory of existing Sigma rules to operate on correctly.
