Check content

Review the web site to determine if HTTP and HTTPs (e.g., 80 and 443) are used in accordance with those ports and services registered and approved for use by the DoD PPSM. Any variation in PPS will be documented, registered, and approved by the PPSM. 1. Open the IIS Manager. 2. Click the site name under review. 3. In the Action Pane, click Bindings. 4. Review the ports and protocols. If unknown ports or protocols are used, then this is a finding.

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.
