Title
Windows 10 account lockout duration must be configured to 15 minutes or greater. (Cat II impact)
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.
