Vulnerability discussion

Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Password length is one factor of several that helps to determine strength and how long it takes to crack a password.The shorter the password, the lower the number of possible combinations that need to be tested before the password is compromised. Use of more characters in a password helps to exponentially increase the time and/or resources required to compromise the password.

Check content

Determine if the network device or its associated authentication server enforces a minimum 15-character password length. This requirement may be verified by demonstration or configuration review. If the network device or its associated authentication server does not enforce a minimum 15-character password length, this is a finding.

Fix text

Configure the network device or its associated authentication server to enforce a minimum 15-character password length.

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.
