DevSecOps: bringing security into your pipelines
Too often, security shows up at the end of a project, once it's too late. DevSecOps brings it in from the start and at every stage of the pipeline: that's the shift left principle.
Scan your dependencies
Most vulnerabilities come from third-party dependencies. Add an automatic scan:
# Example with npm
npm audit --audit-level=high
Tools like Dependabot or Renovate also open update pull requests automatically.
Scan container images
An image can ship vulnerable system packages. Trivy integrates easily in CI:
trivy image --severity HIGH,CRITICAL my-app:1.0
You can fail the pipeline if critical vulnerabilities are found.
Check your Infrastructure as Code
Terraform code or Kubernetes manifests can introduce misconfigurations (public bucket, open port…). Tools like tfsec or Checkov catch them before deployment:
checkov -d .
Handle secrets properly
- Never a plaintext secret in the repository.
- Use a vault (Vault, AWS Secrets Manager) and inject secrets at runtime.
- Add a secret scanner (like gitleaks) to the pipeline to catch leaks.
The right mindset
DevSecOps isn't only about tools: it's a shared responsibility. Security becomes everyone's job, not just an isolated team's.
We put these techniques into practice on real cases in our DevSecOps training. Security is built with every commit.
