Complete HTTP Security Headers Guide
Learn how security headers protect websites, users and sensitive information.
What Are Security Headers?
HTTP security headers are browser instructions sent by a web server to control how browsers handle website content and protect against common attacks.
Why Security Headers Matter
Properly configured security headers reduce risks such as cross-site scripting, clickjacking, data leakage and malicious content execution.
Improve Website Trust
Strong security configuration improves visitor confidence and supports a safer browsing experience.
Important HTTP Security Headers Explained
Strict-Transport-Security (HSTS)
HSTS forces browsers to use HTTPS connections and prevents downgrade attacks from HTTPS to HTTP.
Content-Security-Policy (CSP)
CSP controls which scripts, images and resources browsers are allowed to load, reducing XSS risks.
X-Frame-Options
Protects websites from clickjacking attacks by controlling whether pages can be embedded inside frames.
X-Content-Type-Options
Prevents browsers from incorrectly interpreting file types and reduces MIME sniffing attacks.
Website Security Header Best Practices
Enable HTTPS
Use SSL certificates and redirect HTTP traffic to HTTPS.
Configure HSTS
Force secure browser connections using HSTS policy.
Add CSP Rules
Control allowed scripts and external resources.
Regular Testing
Check security headers after website changes.
