Enterprise Security in Web Design: Content Security Policies (CSP) & Subresource Integrity
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; preloadflags.
