DEADAIR

Summary from the TLDR InfoSec newsletter

deadair is an open-source tool that audits live SIEM rule inventories to identify active detections that are failing silently due to missing, stale, or schema-incompatible telemetry. By utilizing read-only metadata credentials, the tool resolves rule inputs against backend semantics to verify index resolution, document freshness, and ingest lag across Elastic Security and OpenSearch Security Analytics environments. Security engineering teams can deploy deadair to generate fleet-wide coverage reports or to automatically gate candidate detection rules within their CI pipelines.
