Vulnerability discussion

Several vulnerabilities are associated with older versions of web server software. As hot fixes and patches are issued, these solutions are included in the next version of the server software. Maintaining the web server at a current version makes the efforts of a malicious user more difficult.

Check content

Determine the most recent patch level of the IIS 8.5 software, as posted on the Microsoft website. Open the IIS 8.5 Manager. Click "Help", and select "About Internet Information Services". If the version is more than one version behind the most recent patch level, this is a finding.

Fix text

Install the current version of the web server software and maintain appropriate service packs and patches.

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.
