Describes the best practices, location, values, and security considerations for the Account lockout threshold security policy setting. The Account lockout threshold policy setting determines the number of failed sign-in attempts that will cause a user account to be locked.

A locked account cannot be used until you reset it or until the number of minutes specified by the Account lockout duration policy setting expires. If Account lockout threshold is set to a number greater than zero, Account lockout duration must be greater than or equal to the value of Reset account lockout counter after. Brute force password attacks can be automated to try thousands or even millions of password combinations for any or all user accounts. Limiting the number of failed sign-ins that can be performed nearly eliminates the effectiveness of such attacks.

However, it is important to note that a denial-of-service DoS attack could be performed on a domain that has an account lockout threshold configured. A malicious user could programmatically attempt a series of password attacks against all users in the organization.

If the number of attempts is greater than the value of Account lockout thresholdthe attacker could potentially lock every account. Failed attempts to unlock a workstation can cause account lockout even if the Interactive logon: Require Domain Controller authentication to unlock workstation security option is disabled.

It is possible to configure the following values for the Account lockout threshold policy setting:. Because vulnerabilities can exist when this value is configured and when it is not, organizations should weigh their identified threats and the risks that they are trying to mitigate. For information these settings, see Countermeasure in this topic.

The threshold that you select is a balance between operational efficiency and security, and it depends on your organization's risk level. To allow for user error and to thwart brute force attacks, Windows security baselines recommend a value of 10 could be an acceptable starting point for your organization.

As with other account lockout settings, this value is more of a guideline than a rule or best practice because there is no "one size fits all.

Implementation of this policy setting is dependent on your operational environment; threat vectors, deployed operating systems, and deployed apps. For more information, see Implementation considerations in this topic. The following table lists the actual and effective default policy values.

What happens if there's an unusual sign-in to your account

Default values are also listed on the property page for the policy setting. This section describes features and tools that are available to help you manage this policy setting. Changes to this policy setting become effective without a computer restart when they are saved locally or distributed through Group Policy. Implementation of this policy setting is dependent on your operational environment.

You should consider threat vectors, deployed operating systems, and deployed apps, for example:. For more information about Windows security baseline recommendations for account lockout, see Configuring Account Lockout. This section describes how an attacker might exploit a feature or its configuration, how to implement the countermeasure, and the possible negative consequences of countermeasure implementation.

Brute force password attacks can use automated methods to try millions of password combinations for any user account. The effectiveness of such attacks can be almost eliminated if you limit the number of failed sign-in attempts that can be performed. However, a DoS attack could be performed on a domain that has an account lockout threshold configured.

An attacker could programmatically attempt a series of password attacks against all users in the organization. If the number of attempts is greater than the account lockout threshold, the attacker might be able to lock every account without needing any special privileges or being authenticated in the network. Because vulnerabilities can exist when this value is configured and when it is not configured, two distinct countermeasures are defined. Organizations should weigh the choice between the two, based on their identified threats and the risks that they want to mitigate.

The two countermeasure options are:. Configure the Account lockout threshold setting to 0. This configuration ensures that accounts will not be locked, and it will prevent a DoS attack that intentionally attempts to lock accounts.

This configuration also helps reduce Help Desk calls because users cannot accidentally lock themselves out of their accounts. Because it does not prevent a brute force attack, this configuration should be chosen only if both of the following criteria are explicitly met:.Keep in touch and stay productive with Teams and Officeeven when you're working remotely.

Cybercriminals often use the names of well-known companies, like ours, in their scams. They think it will convince you to give them money or your personal information.

Also one would think that if microsoft sends out emails they will be addressed to people by whatever name the individual gave to microsoft when they signed up for an ms account, emails that only refer to the intended reader by their email address are almost well we might as well omit the "almost", i can't imagine any reason a legit email from anyone to anyone else would not refer to the reader by some sort of name, even if that name was just an alias that the reader uses somewhere online guaranteed to be scams.
