We have a security checklist which is available on our website at http://helpnotes.vpcart.com/kb/46-Security-&-Patches/811--SECURITY-CHECKLIST-/. We highly recommend that you go through each option on this page and ensure you have applied it to your site.
Many of the items on this checklist are automatically checked by VPCART when you login to your administration.And if you haven’t completed them, you will be alerted.
