Vulnerability discussion

The longer a password is in use, the greater the opportunity for someone to gain unauthorized knowledge of the passwords. Scheduled changing of passwords hinders the ability of unauthorized system users to crack passwords and gain access to a system.

Check content

Verify the effective setting in Local Group Policy Editor. Run "gpedit.msc". Navigate to Local Computer Policy >> Computer Configuration >> Windows Settings >> Security Settings >> Account Policies >> Password Policy. If the value for the "Maximum password age" is greater than "60" days, this is a finding. If the value is set to "0" (never expires), this is a finding.

Fix text

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Account Policies >> Password Policy >> "Maximum password age" to "60" days or less (excluding "0", which is unacceptable).

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.
