Security Consideration
chmod 755 is the universal standard permission for web server public directories (`public_html`, `/var/www/html`) and executable shell scripts. It allows web servers (like NGINX and Apache) to traverse directories and serve files while preventing external visitors or group members from tampering with the files.
