Is it advisable to publish an app without .htaccess protection on the internet, especially when considering security measures like input validation?

It is not advisable to publish an app without .htaccess protection on the internet, as it leaves the app vulnerable to various security threats. .htaccess protection helps secure the app by restricting access to certain files or directories and preventing unauthorized users from accessing sensitive information. In addition to using .htaccess protection, implementing input validation is also crucial for enhancing the app's security by filtering and sanitizing user input to prevent malicious attacks.

# .htaccess file to restrict access to sensitive directories
<FilesMatch "\.(htaccess|htpasswd|ini|phps|fla|psd|log|sh|inc|bak)$">
    Order Allow,Deny
    Deny from all
</FilesMatch>
