Public web server resources must not be shared with private assets.

From IIS 7.0 WEB SERVER STIG

Part of WG040

SV-32631r2_rule Public web server resources must not be shared with private assets.

Vulnerability discussion

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. Resources, such as, printers, files, and folders/directories must not be shared between public web servers and assets located within the internal network.

Check content

1. From a command prompt, type "net share" and press Enter to provide a list of available shares (including printers). 2. To display the permissions assigned to the shares type "net share" followed by the share name found in the previous step. If any private assets are assigned permissions to the share, this is a finding. If any printers are shared, this is a finding.

Fix text

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.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
