$SIEM_PLATFORM - Target SIEM: splunk, sentinel, elastic, sigma$SECURITY_CONTENT_PATH - Path to detection content repositoryEvery detection rule depends on specific telemetry. This skill maps ATT&CK techniques to the data sources that make detection possible, and compares field naming across common schemas (Splunk CIM, Elastic ECS, Sigma, and Sentinel/MDE).

The same telemetry is named differently across schemas. This table maps common fields across all four platforms.

If you lack a data source, you lack detection capability for techniques that depend on it. Use this mapping to:
Use the data source mapping to determine what infrastructure your test lab needs. See the Test Environment Builder skill for building labs that produce specific data sources.
Generate MITRE ATT&CK Navigator layers for coverage visualization, threat actor mapping, and gap analysis. Produces JSON files compatible with the Navigator web app.
Create grouped detection narratives that tie individual rules into coherent threat stories. Covers Splunk Analytic Stories, Elastic detection rule groups, and Sentinel analytics grouping.
Execute and validate adversary emulation tests using Atomic Red Team. Covers standard atomics, custom atomics (T9999.XXX), deployment workflows, and detection validation.
Build and manage adversary emulation lab environments for any SIEM. Covers Splunk Attack Range, Elastic Security labs, Azure Sentinel labs, and Docker-based setups. Maps data source requirements to infrastructure components.
Expert CTI analyst specializing in detection engineering, MITRE ATT&CK mapping, behavioral analysis, and intelligence-driven detection creation. SIEM-agnostic methodology that works with Splunk SPL, KQL, Sigma, and Elastic. Use when analyzing threat reports, creating detections, mapping MITRE techniques, or developing behavioral analytics.
Create, deploy, and execute custom Atomic Red Team tests (T9999.XXX series) for detection validation. Covers YAML authoring, Ansible deployment, and manual alternatives.
