DevSecOps & CI/CD Security
I engineer CI/CD pipelines where security is embedded from code commit to production release. My methodology follows a strict “shift-left” philosophy, embedding defense-in-depth across stages: code quality, vulnerability scans, policy checks, artifact signing, and Zero Trust delivery gates. I design DevSecOps as a service model—so developers deploy securely, by default.
My pipelines integrate continuous validation of infrastructure, application code, containers, and dependencies using policy-as-code and supply chain integrity tools. With clear separation of duties between dev, security, and infra roles, I enforce least privilege in pipeline steps, isolate secrets, and prevent tampering through cryptographic artifact signing and SLSA provenance.
🔧 Tools & Technologies
- CI/CD Orchestration: GitHub Actions, GitLab CI, Jenkins, ArgoCD, Tekton
- Infrastructure Scanning: Terraform Validate, Checkov, tfsec, Sentinel, Regula
- Code & Image Security: SonarQube, Semgrep, Grype, Trivy, Clair, Syft
- Policy & Compliance: OPA Gatekeeper, Sentinel, Conftest, InSpec
- Supply Chain & Signing: Cosign, Sigstore, Rekor Transparency Log, SLSA Framework
- Secrets Management: HashiCorp Vault, AWS Secrets Manager, Doppler
📌 Real-World Implementation
In my GCP Secure DevSecOps Pipeline project, I architected an end-to-end secure delivery flow for a containerized microservices platform:
- Pre-commit: Applied Git hooks for Terraform linting, policy validation, and inline tfsec reports for developers
- SAST: Used Semgrep for language-aware code scanning with custom rules to enforce business-specific logic flaws
- DAST: Integrated OWASP ZAP in staging pipelines to auto-scan deployed preview apps with context-aware crawling
- Container Security: Implemented SBOM generation using Syft, and image scanning with Trivy/Grype pre-deploy
- Artifact Integrity: Signed all images with Cosign and stored metadata in the Rekor transparency log
- ArgoCD + Policy Gates: Applied promotion gates via OPA to prevent unverified images from being pulled in production
- Separation of Roles: Maintained distinct CI runner roles with ephemeral secrets via Vault and short-lived credentials
📈 Outcomes & Impact
- ✅ Embedded security checks early—cut vulnerability remediation time by 60%
- ✅ Ensured full traceability and non-repudiation of every build with signed provenance
- ✅ Enabled zero-touch, policy-enforced, secure deployments across multi-cloud workloads
- ✅ Passed compliance checks for SOC2, SLSA Level 2, and ISO 27001 with codified evidence pipelines
