Static sites eliminate entire attack vectors by architecture. No database = no SQL injection. No PHP = no remote code execution. No plugins = no third-party vulnerabilities. WordPress sites face 98× more attack attempts (WP Scan, 2025). GitHub CMS with nginx, SSL, and Content-Security-Policy headers provides defense in depth without requiring a security team.
Attack Vectors Eliminated
| Attack Type | WordPress | Static GitHub CMS |
|---|---|---|
| SQL Injection | Vulnerable (MySQL) | Impossible (no database) |
| PHP RCE | Vulnerable | Impossible (no PHP) |
| Plugin exploits | 55,000+ known vulns | Impossible (no plugins) |
| XSS via comments | Possible | Not applicable |
| Brute force login | wp-login.php targeted | No login page |
| DDoS | Mitigated by cache | Static files — highly resilient |
Security Headers
GitHub CMS deploys with recommended security headers via nginx:
add_header X-Content-Type-Options nosniff;
add_header X-Frame-Options SAMEORIGIN;
add_header X-XSS-Protection "1; mode=block";
add_header Referrer-Policy "strict-origin-when-cross-origin";
add_header Content-Security-Policy "default-src 'self'";
CI/CD Security Checks
Every push triggers automated security validation: 368 tests check for secrets in build output, validate SSL certificates, and verify deployment integrity.
Summary
Static architecture is the strongest security posture available for websites. No runtime, no database, no plugins — nothing to exploit. GitHub CMS delivers this security by default.
