From Grade F to A+: The Ultimate HTTP Security Headers Guide

If you deploy a standard Nginx or Apache server today, it is insecure by default. While your firewall might be strong, your browser communication is wide open to MIME Sniffing, Clickjacking, and XSS attacks. At iRexta, we audited hundreds of servers only to find most running on a "Grade F" security score. Here is how you fix it using the "Big 6" Security Headers. 🛡️ The Security Checklist HSTS (Strict-Transport-Security): Forces HTTPS. No more SSL stripping. CSP (Content-Security-Policy): The primary defense against XSS. Permissions-Policy: Explicitly disables access to Camera/Mic/Geo APIs. X-Content-Type-Options: Stops the browser from "guessing" file types (MIME sniffing). X-Frame-Options: Prevents your site from being framed (Anti-Clickjacking). Referrer-Policy: Protects user privacy during navigation. 🛠️ Nginx Implementation Snippet Add this to your server block to harden your iRexta Dedicated Server instantly: # 1.
