Information
It is important to segregate public web server resources from private resources located behind the DoD DMZ in order to protect private assets. When folders, drives or other resources are directly shared between the public web server and private servers the intent of data and resource segregation can be compromised.
In addition to the requirements of the DoD Internet-NIPRNet DMZ STIG that isolates inbound traffic from the external network to the internal network, resources such as printers, files, and folders/directories will not be shared between public web servers and assets located within the internal network.
Solution
Configure the public web server to not have a trusted relationship with any system resource that is also not accessible to the public. Web content is not to be shared via Microsoft shares or NFS mounts.
