DevSecOps Pipeline Hardening and Software Supply Chain Security
Embedded security controls across the software delivery pipeline for a financial-services environment where audit requirements, vulnerability management, and supply chain integrity needed to be addressed at the platform level rather than left to individual teams.
Technical Implementation
- Introduced image vulnerability scanning with Trivy and Grype at the container build stage in GitHub Actions pipelines, configured severity thresholds and fail policies, and established a base image management process so teams consumed pre-approved, regularly updated images rather than pulling arbitrary upstream tags.
- Implemented SBOM generation with Syft at build time and integrated SBOM attestation into the container registry so every pushed image had a signed artifact manifest covering its component inventory, enabling downstream audit and license compliance checks.
- Deployed OPA Gatekeeper with a set of ConstraintTemplates covering disallowed capabilities, required resource limits, disallowed image registries, mandatory labels, and privilege escalation prevention so admission-time enforcement at the cluster boundary reinforced the pipeline controls.
- Added Cosign-based image signing into the CI pipeline and configured admission webhook verification so only images produced by the approved pipeline could reach production namespaces, providing an auditable chain of custody from commit to deployment.
Client Delivery & Handover
The work was run with the client security, platform, and application delivery teams because pipeline controls, registry policies, and admission enforcement all had to be agreed across those functions before rollout. Security requirements were mapped to technical controls first, then controls were introduced in enforcement mode on lower environments while running in audit mode on production to allow teams to remediate before hard enforcement landed. Handover included security control documentation, pipeline templates, OPA policy library, image signing procedures, and training for both platform engineers and application teams on policy intent and exception handling.
Outcome
The delivery pipeline moved from informal security checks to a documented, enforced control model with audit evidence at each stage, giving the security team better visibility into what was being deployed and reducing reliance on manual review for compliance sign-off.
