DevOps Fundamentals Roadmap

Align with FISMA, FedRAMP, and NIST frameworks. Maintain immutable audit logs, implement access logging, conduct regular compliance scanning, and perform quarterly security assessments and penetration testing.

Use Kubernetes with hardened configurations, Pod Security Standards, network policies, and service mesh. Scan all container images for CVEs, sign images with cryptographic signatures, and maintain SBOM for all releases.

Use a fork-and-pull model with branch protection rules requiring code review and status checks. Tag releases semantically, maintain clear changelogs for audit purposes, and review all external contributions thoroughly.

Use modular Terraform modules or CloudFormation nested stacks that don't expose sensitive details. Parameterize everything, maintain separate state files for different classification levels, and use remote state in encrypted backends.

Open source DevOps requires additional security considerations since source code is publicly accessible. You must assume malicious actors will examine your code, implement stricter secret management, and maintain clear separation between public frameworks and private deployment configurations.

Never commit secrets to repositories. Use secret management tools like HashiCorp Vault or AWS Secrets Manager, implement automated secret scanning in CI/CD pipelines, and use sealed-secrets for Kubernetes deployments.

Critical tools include: SAST scanners (SonarQube, Checkmarx), dependency scanners (Snyk, OWASP Dependency-Check), secret scanners (git-secrets, TruffleHog), container scanners (Trivy, Clair), and compliance tools (OPA, Sentinel).

The key is layered security: open source non-sensitive logic and frameworks while keeping deployment configurations, infrastructure definitions, and agency-specific customizations private. Use templating systems that allow public templates with private value files.
