DoD Component – Large-Scale SIEM Ingest Automation

Context

Sector: U.S. Department of Defense
Role: Solutions Architect / Automation Engineer
Environment: High-volume security event ingestion infrastructure. Production environments operated within controlled facilities (no direct production access).

Challenge

• Deploy and standardize SIEM ingest infrastructure across hardened DoD servers.
• Align automation with strict OS baselines and security controls.
• Ensure compatibility with downstream tooling built on Elasticsearch.
• Enable repeatable deployments into production without direct engineer access.

Architecture & Implementation

• Designed and authored hardened Ansible playbooks tailored to DoD server baselines.
• Engineered log forwarding and transformation pipelines aligned with Elasticsearch ingest requirements.
• Built automation suitable for promotion into production-controlled environments (including SCIF-operated deployments).
• Tuned configurations to support sustained high-volume event ingestion.

Outcomes

• Standardized SIEM ingest infrastructure across production environments.
• Eliminated configuration drift through hardened infrastructure-as-code (IaC).
• Reduced deployment time and operational overhead for SCIF-operated systems.
