Vulnerability discussion

Web Sharing is non-essential and must be disabled. Enabling any service increases the attack surface for an intruder. By disabling unnecessary services, the attack surface is minimized.

Check content

To check if the "Web Sharing" service is disabled, use the following command: /usr/bin/sudo /bin/launchctl print-disabled system | /usr/bin/grep org.apache.httpd If the results do not show the following, this is a finding. "org.apache.httpd" => true

Fix text

To disable the "Web Sharing" service, run the following command: /usr/bin/sudo /bin/launchctl disable system/org.apache.httpd The system may need to be restarted for the update to take effect.

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.
