Frequently Asked Questions
HTTP security headers are special HTTP response headers that your server can send to the browser to increase the security of your website. These headers tell the browser how to behave when handling your website's content and can help protect against various attacks like XSS (Cross-Site Scripting), clickjacking, and other code injection attacks.
Security headers are important because they provide an additional layer of security for your website. They help protect against common web vulnerabilities and attacks by instructing browsers how to handle your content. Properly configured security headers can prevent attackers from exploiting vulnerabilities, even if they exist in your application. They're a simple yet effective way to enhance your website's security posture.
The implementation of security headers depends on your web server or hosting environment:
- Apache: Add headers to your .htaccess file or server configuration
- Nginx: Add headers in your server or location block
- IIS: Configure headers in your web.config file
- Express (Node.js): Use the helmet middleware
- PHP: Use the header() function
- Django: Configure MIDDLEWARE settings
- Ruby on Rails: Use the secure_headers gem
Our security rating system evaluates the presence and configuration of important security headers:
- A (Excellent): All critical security headers are properly implemented
- B (Good): Most critical security headers are implemented, with minor improvements possible
- C (Average): Some security headers are implemented, but important ones are missing
- D (Poor): Few security headers are implemented, leaving the site vulnerable
- F (Failing): Critical security headers are missing, posing significant security risks
