🚀 Advanced Nginx Configuration

This document contains configuration files for setting up security headers in Nginx. These settings enhance security by mitigating common web vulnerabilities.

🌍 Server Configuration​

📜 /etc/nginx/sites-available/asifahmadkhan.com.conf​

server {
    listen      80;
    listen      [::]:80;

    root        /var/www/html/index.html; ## PROJECT PATH

    # 🔐 Security settings
    include     nginxconfig.io/security.conf;

    # 📜 Logging
    access_log  /var/log/nginx/access.log combined buffer=512k flush=1m;
    error_log   /var/log/nginx/error.log warn;

    # 🌎 Serve static files with fallback to index.html
    location / {
        try_files $uri $uri/ /index.html;

add_header Content-Security-Policy "default-src 'self' http: https: ws: wss: data: blob: 'unsafe-inline'; frame-ancestors 'self';" always;
add_header Permissions-Policy      "interest-cohort=()" always;

# 🚫 Deny access to dotfiles (except .well-known)
location ~ /\.(?!well-known) {
    deny all;
}

🛠️ General Configurations​
