SV-60833r1_rule Users must not reuse the last 5 passwords.

Vulnerability discussion

Password complexity, or strength, is a measure of the effectiveness of a password in resisting guessing and brute-force attacks. To meet password policy requirements, passwords need to be changed at specific policy-based intervals. If the operating system allows the user to consecutively reuse their password when the password has exceeded its defined lifetime, the end result is a password that is not changed, per policy requirements.

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.
