Check content

Determine if the network device automatically locks the account until the locked account is released by an administrator when three unsuccessful login attempts in 15 minutes are exceeded. This requirement may be verified by demonstration or configuration review. This requirement may be met through use of a properly configured authentication server if the device is configured to use the authentication server. If an account is not automatically locked out until the locked account is released by an administrator when three unsuccessful login attempts in 15 minutes are exceeded, this is a finding.

Fix text

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.
