Web Security Headers: A Comprehensive Guide to Protecting Your Site
Security
February 26, 2025
Discover the essential HTTP security headers every website needs. Learn how to implement CSP, HSTS, and X-Frame-Options to prevent common attacks.
HTTP security headers are a fundamental part of web security. They configure your browser to enable built-in defenses against common vulnerabilities like XSS and clickjacking.
Essential Security Headers
Implement these headers immediately to improve your security posture:
Content-Security-Policy (CSP)
CSP helps prevent Cross-Site Scripting (XSS) and data injection attacks by restricting where resources can be loaded from.
Strict-Transport-Security (HSTS)
Enforces secure (HTTP over SSL/TLS) connections to the server, protecting against protocol downgrade attacks.
X-Frame-Options
Prevents clickjacking by controlling whether your site can be rendered in a <frame>, <iframe>, or <object>.
⚠️ Don't Ignore These:
- X-Content-Type-Options: Prevents MIME-sniffing
- Referrer-Policy: Controls how much referrer information is sent
