Security & Performance
Security & Performance Capstone: Production Audit
Security & Performance Capstone: Production Audit
This lesson adds advanced coverage to Security & Performance based on the official documentation and practical production work.
Focus for this lesson: reviewing a full app across OWASP controls and Core Web Vitals.
Learning Goals
- Understand the core idea and when to use it.
- Apply it in a real project without breaking security or performance.
- Connect it to tests, documentation, and monitoring when needed.
Practical Example
// audit: auth, input, output, deps, headers, vitals, logs, rollback
Documentation reference: OWASP Cheat Sheets and web.dev Performance.
Professional Implementation Steps
- Review boundaries and responsibilities before writing code.
- Build a small example and then apply it to a real feature.
- Add a test or smoke check that proves the behavior.
- Document the impact on maintenance and deployment.
Hands-on Practice
Apply this topic to an existing page, API, or component, then review the result for maintainability, security, performance, and user experience.
Production addition: do not judge success only by running the example. Judge it by how clear, testable, and maintainable the decision is.
Avoid copying documentation patterns blindly. Tie every option to a clear project reason.
Summary
Add this topic to your toolbox as an engineering decision that can be explained, tested, and reviewed.
