WN25-AC-000020 - Windows Server 2025 must have the number of allowed bad logon attempts configured to three or less.
Information
The account lockout feature, when enabled, prevents brute-force password attacks on the system. The higher this value is, the less effective the account lockout feature will be in protecting the local system. The number of bad logon attempts must be reasonably small to minimize the possibility of a successful password attack while allowing for honest errors made during normal user logon.Solution
Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Account Policies >> Account Lockout Policy. Set 'Account lockout threshold' to '3' or fewer invalid logon attempts (excluding '0', which is unacceptable).See Also
