FAQPage Schema
How do I create and test LimaCharlie Detection & Response rules?▼

To create LimaCharlie D&R rules, use template-driven authoring for common use cases like brute force or beaconing, then validate syntax and behavior by running replay and unit tests before deployment.

What are LimaCharlie D&R rules used for in security monitoring?▼

LimaCharlie D&R rules detect threats like LOLBins and beaconing by analyzing structured detect_data, returning alerts enriched with metadata and MITRE mappings for audit resilience and threat tracking.

Why are my LimaCharlie D&R rules triggering alert storms?▼

Alert storms often result from misconfigured rule structures. Validate syntax, run unit tests to verify behavior, and follow troubleshooting guidance to ensure metadata and detect_data are correctly structured.

Can I validate LimaCharlie rule syntax before deploying to production?▼

Yes, you can validate rule syntax before deployment by using in-line testing workflows. Draft the rule, analyze its structure, and run replay tests to ensure safe production rollout.

What is the best way to troubleshoot misconfigured LimaCharlie D&R rules?▼

The best way to troubleshoot misconfigured rules is to analyze rule structures for errors, run unit tests to isolate behavior issues, and verify that metadata and MITRE mappings are properly included.
