Vulnerability discussion

Web servers provide numerous processes, features, and functionalities that use TCP/IP ports. Some of these processes may be deemed unnecessary or too unsecure to run on a production system.The web server must provide the capability to disable or deactivate network-related services that are deemed to be non-essential to the server mission, are too unsecure, or are prohibited by the Ports, Protocols, and Services Management (PPSM) Category Assurance List (CAL) and vulnerability assessments.

Check content

Review the web server documentation and deployment configuration to determine which ports and protocols are enabled. Verify the ports and protocols being used are permitted, necessary for the operation of the web server and the hosted applications, and are secure for a production system. Open the <'INSTALLED PATH'>\conf\httpd.conf file. Verify only the listener for port 443 is returned. If any of the ports or protocols are not permitted, are nonsecure, or are not necessary for web server operation, this is a finding.

Fix text

Open the <'INSTALLED PATH'>\conf\httpd.conf file. Verify the "Listen" directives are configured only for port 443.

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.
