Architectural Analysis: Highclasswebdesign Engineering Directorate • WCAG & CWV Standards Audited

A pristine design is worthless if compromised by client-side security vulnerabilities. Implementing strict HTTP response headers protects brand reputation.

1. Essential Security Headers for Modern Websites

  • Content-Security-Policy (CSP): Restricts script execution strictly to verified first-party domains and whitelisted CDNs.
  • Subresource Integrity (SRI): Cryptographically hashes external script assets (integrity="sha384-...") to prevent third-party CDN tampering.
  • Strict-Transport-Security (HSTS): Enforces SSL/TLS encryption across all subdomains with includeSubDomains; preload flags.
