Vulnerability discussion

Private web servers, which host sites that serve controlled access data, must be protected from outside threats in addition to insider threats. Insider threat may be accidental or intentional but, in either case, can cause a disruption in service of the web server. To protect the private web server from these threats, it must be located on a separate controlled access subnet and must not be a part of the public DMZ that houses the public web servers. It also cannot be located inside the enclave as part of the local general population LAN.

Check content

Verify the site’s network diagram and visually check the web server, to ensure that the private web server is located on a separate controlled access subnet and is not a part of the public DMZ that houses the public web servers. In addition, the private web server needs to be isolated via a controlled access mechanism from the local general population LAN.

Fix text

Isolate the private web server from the public DMZ and separate it from the internal general population LAN.

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.
