Ensure Web Content Located on Separate partition

Description

The DocumentRoot directory is used for storing web content and data. Ensure that the DocumentRoot directory exists on a separate logical volume at installation time, or migrate it using LVM.

Rationale

Application partitioning enables an additional security measure by securing user traffic under one security context, while managing system and application files under another. Web content is can be to an anonymous web user. For such an account to have access to system files of any type is a major security risk that is avoidable and desirable. Failure to partition the system files from the web site documents increases risk of attack via directory traversal, or impede web site availability due to drive space exhaustion.
