OpenCart is an open-source, PHP based eCommerce solution for online merchants. Being open source it has some negative traits. One of the negative aspect is that anyone can access the core code to understand it’s working.
To improve the security of your store from unauthorized parties, we would suggest you to perform the following security steps immediately after completing the Opencart installation.
1. Once you complete the installation process of OpenCart, you should remove the /install/ directory using FTP program.
2. Change the file permissions for the config.php file in both the root directory and the /admin/ directories to 444.
