SV-52876r1_rule Users must be warned in advance of their passwords expiring.

Vulnerability discussion

Creating strong passwords that can be remembered by users requires some thought. By giving the user advance warning, the user has time to construct a sufficiently strong password. This setting configures the system to display a warning to users telling them how many days are left before their password expires.

Check content

If the following registry value does not exist or is not configured as specified, this is a finding: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \Software\Microsoft\Windows NT\CurrentVersion\Winlogon\ Value Name: PasswordExpiryWarning Value Type: REG_DWORD Value: 14 (or greater)

Fix text

Configure the policy value for Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> "Interactive Logon: Prompt user to change password before expiration" to "14" days or more.

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.
