Detection-to-Remediation Orchestration

Cross-cutting — read this before/alongside the rest
EventBridge · SNS/SQS · Lambda · SSM Automation · Config Remediation · Step Functions · Security Hub Custom Actions vs Automation Rules 16 cards · 9 Q

The direct answer to "does a finding auto-execute, or does it need wiring?" No detective service fixes anything by default — this guide is the orchestration layer connecting every finding-generating service in this library to an actual remediation action. Built around a Preventive → Detective → Responsive → Remediation framework.
