DAST and API Security Testing

DAST and API Security Testing

This lesson deepens DevSecOps & Supply Chain Security using the same subject areas emphasized by official documentation: OWASP, SLSA and Sigstore docs: SAST, DAST, dependencies, containers, SBOMs, signing, provenance and remediation. The goal is to turn DAST and API Security Testing into a production skill: you should know the concept, the configuration surface, the safety controls, the operational checks, and the rollback path.

Documentation Coverage

• Core terms and object model for this topic.
• Configuration options, defaults, and lifecycle behavior from the docs.
• Security, reliability, and ownership boundaries.
• Validation steps before and after the change.
• Common failure modes and diagnostic signals.

Production Implementation Flow

1. Define the source of truth: Git, configuration, API, state file, or control plane.
2. Design the safest repeatable workflow, including dry-run or plan output where possible.
3. Attach CI/CD, policy, security, and peer-review gates.
4. Observe metrics, logs, events, or traces after the change.
5. Document rollback, escalation owner, and evidence for the change record.

Mastery Standard

You understand DAST and API Security Testing when you can explain it, configure it, test it, monitor it, and recover it under incident pressure without relying on undocumented manual steps.
