Detection Engineering: Practicing Detection-as-Code – Deployment – Part 6

This document outlines best practices and practical implementations for deploying detection rules to SIEM/XDR platforms—primarily Microsoft Sentinel—using Azure DevOps. It details API consumer considerations (authentication, rate limiting, error handling), secure credential handling (Key Vault, service connections, managed identities), pipeline orchestration with agents, and multiple deployment strategies: manual runs, release-branch/tag triggers, repository-change triggers via Git analysis, and multitenant parallelization via matrix jobs. The guide includes YAML and Python examples to automate rule deployments reliably across environments.
