PCI Compliance for Plesk (linux)

The following guide assumes you are working with a Plesk 8.6 (or above) installation on RedHat Enterprise or CentOS Linux. You will need shell / root access to your server running Plesk, if you do not have shell / root access then you will need to ask your server hosts to make the changes.
WARNING:This document does not serve as a comprehensive source for PCI compliance advice. The reader is expected to have some basic systems administration experience. Do not copy and paste examples directly from this document without first understanding their implications.
