The three folders "attachments", "downloads" and "templates_c" need to be writeable by WHMCS and therefore require the permissions 777 (writeable by all).  When folders have this permission level it is safer to place the folders outside of the public accessible folder tree on your website.  WHMCS allows you to do this.  If you do move the folders, then you must tell WHMCS where they have been moved to by adding the following lines to your configuration.php file:

Note that if you are running suphp or phpsuexec you should not make the mode changes as the folders will already be writeable. In fact, you cannot set folder or file permissions to be 777 when running suphp or phpsuexec - the highest permissions are 755 for both folders and files.

Malicious users who visit your site and recognise a WHMCS install will know that they can try logging into your admin area via the admin folder.  To protect against this, you can rename the admin folder name to any name you like.  You cannot move the folder - only rename it.  You can then tell WHMCS what the name of that folder is for the links in admin notification emails by adding the following line to your configuration.php file:<br />

WHMCS includes many features to help keep your data safe, but you can take recommended additional steps to secure your WHMCS installation further.

Recommended Steps

We recommend:

  1. Securing the writeable directories by moving them to a non-public location.
  2. Securing the configuration.php file by adjusting its permissions.
  3. Securing the crons directory by moving it to a non-public location.
  4. Protecting your Admin Area by restricting access to a specific set of IP addresses and renaming the admin directory.
  5. Disabling any unneeded database privileges.
  6. Protecting sensitive data by enabling SSL.
  7. If you are not using Apache, ensure against serving requests directly from the vendor directory.
    The .htaccess file within the vendor directory will suffice to protect against this for servers running on Apache.
  8. Defending against clickjacking by always sending the proper Content Security Policy (CSP) frame-ancestors directive response headers.
  9. Performing general server hardening measures (for example, cPanel's or OWASP's best practices).

Additional Questions

If you have additional questions or concerns regarding server security, contact your hosting provider or system administrator. They can review the server, assess the installed software and configuration, and provide tailored recommendations and assistance.
