🛡️ Cybersecurity Review Guide for React & Vite Applications

Conducting a cybersecurity review is essential for identifying vulnerabilities, enforcing secure development practices, and protecting user data. Here’s a structured approach tailored specifically for modern frontend stacks like React and Vite.

1.🎯 Define the Scope
Start with clear objectives:
Assess your application against threats like:

XSS (Cross-Site Scripting)
CSRF (Cross-Site Request Forgery)
Data leaks
Insecure storage
Misconfigured permissions

Include in your scope:
✅ Frontend code
✅ APIs
✅ Build outputs
✅ Deployment configurations

2.🔍 Static & Dependency Analysis

Run yarn audit or npm audit for known vulnerabilities.
Regularly update outdated or vulnerable dependencies.
Search for hard-coded secrets or API keys.
Exclude source maps from production builds to avoid exposing internal code.

3.🛡️ Security Headers & Configs
Ensure critical HTTP security headers are properly set:

- Content-Security-Policy
- X-Frame-Options / frame-ancestors
- Strict-Transport-Security
- X-Content-Type-Options
Use tools like OWASP ZAP to automate header checks and identify gaps.

4.🔐 Access Control (RBAC)

Enforce Role-Based Access Control both in the frontend and backend.
Ensure users can only access views/actions authorized to their roles.
Never rely solely on frontend checks—always validate on the server too.

5.🧼 Input & Output Sanitization

Validate and sanitize all user input (client + server).
Avoid dangerouslySetInnerHTML unless fully sanitized.
Escape dynamic content in rendering or DOM manipulation.

6.🌐 CORS Policy Review

Allow only specific trusted origins.
Avoid * unless absolutely needed (e.g., public APIs).
Block credentials unless they’re essential.

7.🕵️ Sensitive Data Exposure
Ensure no sensitive data (PII/PHI) is leaked via:

API responses
Error messages
Console logs
Check both dev and prod environments for test/debug endpoints.

8.🔒 Data Storage & Encryption

Avoid storing sensitive tokens in localStorage or sessionStorage.
Prefer HttpOnly cookies for auth tokens to reduce XSS risk.
Ensure encryption at rest for sensitive data like PHI or financial info.

9.📦 Production Build Inspection

Verify your production build:
Is minified and optimized.
Removes all console.* and debugger statements (via Terser, etc.).
Does not expose sourcemaps or internal paths.

10.🛠️ Automated Scanning & Testing
Use these tools to automate and reinforce your security posture:

OWASP ZAP – Dynamic security testing
Snyk or Dependabot – Dependency monitoring
Lighthouse – Performance, accessibility, and basic security audits

✅ Summary
Cybersecurity isn’t a one-time task—it's an ongoing process. Even with modern stacks like React and Vite, you must stay vigilant. Regular audits, secure coding practices, and automation go a long way toward securing your app and users.
