Vulnerability discussion

Permitting passwords to be changed in immediate succession within the same day allows users to cycle passwords through their history database. This enables users to effectively negate the purpose of mandating periodic password changes.

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 "Minimum password age" is set to "0" days ("Password can be changed immediately."), this is a finding.

Fix text

Configure the policy value for Computer Configuration -> Windows Settings -> Security Settings -> Account Policies -> Password Policy -> "Minimum password age" to at least "1" day.

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.
