This project implements multiple layers of security:

• SLSA Level 3 Provenance - Build integrity verification via GitHub Actions
• GitHub Attestations - Verifiable build provenance in repository UI
• Sigstore Signing - Cryptographic image signatures with cosign
• SBOM Generation - Software Bill of Materials (CycloneDX format)
• Trivy Vulnerability Scanning - Automated CVE detection in dependencies
• Content Security Policy (CSP) - Strict CSP with per-request nonces
• Security Headers:
  • X-Frame-Options: SAMEORIGIN - Mitigates clickjacking by allowing framing only from the same origin
  • X-Content-Type-Options: nosniff - Prevents MIME sniffing
  • Referrer-Policy: strict-origin-when-cross-origin - Privacy protection
  • Strict-Transport-Security - HSTS with preload (production)
  • Permissions-Policy - Disables unnecessary browser features

• React 19 Security Features - Built-in XSS protection
• Next.js Security - Server-side rendering with sanitization
• No Inline Scripts - All scripts use Next.js Script component with nonces
• Safe External Links - All external links use rel="noopener noreferrer"
• Input Validation - All user inputs validated and sanitized
• Error Handling - Framework-level error pages and logging help avoid sensitive information disclosure

• Server-Side Analytics - No client-side tracking scripts (CSP-compliant)
• No Third-Party Cookies - Minimal data collection
• GDPR Compliant - Privacy-first architecture
• Transparent Data Handling - Clear privacy policy

• Regular Updates - Automated dependency updates
• Audit Checks - Pre-build security audits
• Minimal Dependencies - Only essential packages included
• Lock Files - Deterministic dependency resolution
