Vulnerability discussion

The account lockout feature, when enabled, prevents brute-force password attacks on the system. This parameter specifies the amount of time that an account will remain locked after the specified number of failed logon attempts.

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 >> Account Lockout Policy. If the "Account lockout duration" is less than "15" minutes (excluding "0"), this is a finding. Configuring this to "0", requiring an administrator to unlock the account, is more restrictive and is not a finding.

Fix text

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Account Policies >> Account Lockout Policy >> "Account lockout duration" to "15" minutes or greater. A value of "0" is also acceptable, requiring an administrator to unlock the account.

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.
