Managing SIEM Log Collectors at Scale with Ansible and GitHub Actions – Part 1

The report describes a DevOps and Infrastructure-as-Code solution to manage SOC SIEM log collectors at scale, addressing challenges such as evidence integrity, detection quality, and attack surface. It details an architecture centered on GitHub repositories, an Ansible control node, secure VPN access, and automated GitHub Actions workflows to enforce consistent configuration, automate deployments and updates, validate health, and enable rapid rollback and recovery. By codifying collector setup and operations, the approach improves uptime, reliability, and auditability, reducing manual effort and risk while accelerating onboarding and restoration of collectors.
