This lesson

This lesson teaches Secrets Management: security mindset, common threats, and defensive practices for software teams.

Leaked API keys in git remain a top incident cause—secrets hygiene is daily work.

You will apply Secrets Management in contexts like: Web apps, APIs, CI/CD, and organizational compliance programs.

Read scenario-based lessons, map controls to code you write on other tracks, and complete MCQs—practice threat modeling on paper or in docs.

When you can explain the previous lesson's ideas in your own words.

API keys, DB passwords, and TLS private keys are secrets—never in git, screenshots, or client-side mobile apps.

Storage

Environment variables via secret managers (AWS Secrets Manager, HashiCorp Vault, Doppler)—inject at runtime in CI/CD.

Rotate after staff departures and suspected leaks; automate where possible.

Mobile/SPA cannot hide embedded keys—use backend proxy for third-party APIs.

Pitfall: Secrets in CI logs—mask outputs and use OIDC to cloud roles.
