Vulnerability discussion

Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Use of a complex password helps to increase the time and resources required to compromise the password. The more complex the password is, the greater the number of possible combinations that need to be tested before the password is compromised. Special characters are those characters that are not alphanumeric. Examples include: ~ ! @ # $ % ^ *.

Check content

If the AAA Service relies on directory services for user account management this is not applicable and the connected directory services must perform this function. Where passwords are used, verify the AAA Service is configured to enforce password complexity by requiring that at least one special character be used. This requirement may be verified by demonstration or configuration review. If the AAA Service is not configured to require that at least one special character be used, this is a finding.

Fix text

Configure the AAA Service to enforce password complexity by requiring that at least one special character be used.

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.
