What you'll learn

  • Explain DevSecOps, shift left and shared ownership, and threat model a feature with STRIDE.
  • Prevent injection and XSS with parameterised queries, allow-list validation and output encoding.
  • Keep secrets out of code with scanning, secret managers and OIDC short-lived credentials.
  • Wire SAST, dependency scanning, SBOM generation, image scanning and IaC scanning into CI/CD.
  • Harden CI systems, sign artefacts with cosign and reason about SLSA provenance.
  • Secure runtime with DAST, Kubernetes pod hardening, least-privilege IAM and policy as code.
  • Triage vulnerabilities by risk, respond to incidents and avoid common DevSecOps pitfalls.
