Vulnerability discussion

The web server has several remote communications channels. Examples are user requests via http/https, communication to a backend database, or communication to authenticate users. The encryption used to communicate must match the data that is being retrieved or presented.Methods of communication are http for publicly displayed information, https to encrypt when user data is being transmitted, VPN tunneling, or other encryption methods to a database.

Check content

Review the web server documentation and configuration to determine the communication methods that are being used. Verify the encryption being used is in accordance with the categorization of data being hosted when remote connections are provided. If it is not, then this is a finding.

Fix text

Configure the web server to use encryption strength equal to the categorization of data hosted when remote connections are provided.

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.
