I made my cybersecurity fundamentals guide completely free. No email gate, no sign-up wall — just download it.
Why Free?
Because every developer ships code that handles user data. And too many security breaches happen because developers didn't learn the basics.
What's Covered
- Authentication & Authorization — OAuth, JWT, session management done right
- Input Validation — SQL injection, XSS, command injection prevention
- Encryption Basics — When to use symmetric vs asymmetric, hashing patterns
- Secure API Design — Rate limiting, CORS, API key management
- Common Vulnerabilities — OWASP Top 10 with practical examples
- Security Headers — CSP, HSTS, X-Frame-Options explained
- Dependency Security — Auditing packages, supply chain risks
