## To what extent are tests representative of protection in the real world?
It is important to remember that Microsoft sees a wider and broader set of threats beyond whats tested in the antivirus evaluations highlighted above. Windows Defender AV encounters ~200 million samples every month, and the typical antivirus test consists of between 100-5,000 samples. The vastness of the malware landscape makes it extremely difficult to evaluate the quality of protection against real world threats.

# Account lockout threshold
@ -22,22 +22,22 @@ Describes the best practices, location, values, and security considerations for
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](account-lockout-duration.md) policy setting expires. You can set a value from 1 through 999 failed sign-in attempts, or you can specify that the account will never be locked by setting the value to 0. 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](reset-account-lockout-counter-after.md).
Failed password attempts on workstations or member servers that have been locked by using CTRL+ALT+DELETE or password-protected screen savers do not count as failed sign-in attempts unless [Interactive logon: Require Domain Controller authentication to unlock workstation](interactive-logon-require-domain-controller-authentication-to-unlock-workstation.md) is set to **Enabled**. If Interactive logon: Require Domain Controller authentication to unlock workstation is enabled, repeated failed password attempts to unlock the workstation will count against the account lockout threshold.
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 threshold**, the 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](interactive-logon-require-domain-controller-authentication-to-unlock-workstation.md) security option is disabled. Windows doesnt need to contact a domain controller for an unlock if you enter the same password that you logged on with, but if you enter a different password, Windows has to contact a domain controller in case you had changed your password from another machine.
### Possible values
It is possible to configure the following values for the **Account lockout threshold** policy setting:
- A user-defined number from 0 through 999
- Not defined
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](#bkmk-countermeasure) in this topic

### Best practices
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, a setting above 4 and below 10 could be an acceptable starting point for your organization.

- When negotiating encryption types between clients, servers, and domain controllers, the Kerberos protocol can automatically retry account sign-in attempts that count toward the threshold limits that you set in this policy setting. In environments where different versions of the operating system are deployed, encryption type negotiation increases.
- Not all apps that are used in your environment effectively manage how many times a user can attempt to sign-in. For instance, if a connection drops repeatedly when a user is running the app, all subsequent failed sign-in attempts count toward the account lockout threshold.

- A robust audit mechanism is in place to alert administrators when a series of failed sign-ins occur in the environment.
- Configure the **Account lockout threshold** policy setting to a sufficiently high value to provide users with the ability to accidentally mistype their password several times before the account is locked, but ensure that a brute force password attack still locks the account.
A good recommendation for such a configuration is 50 invalid sign-in attempts, which prevents accidental account lockouts and reduces the number of Help Desk calls, but does not prevent a DoS attack. We recommend this option if your organization cannot implement complex password requirements and an audit policy that alerts administrators to a series of failed sign-in attempts.
[Windows security baselines](https://docs.microsoft.com/windows/security/threat-protection/windows-security-baselines) recommend configuring a threshold of 10 invalid sign-in attempts, which prevents accidental account lockouts and reduces the number of Help Desk calls, but does not prevent a DoS attack.
Using this type of policy must be accompanied by a process to unlock locked accounts. It must be possible to implement this policy whenever it is needed to help mitigate massive lockouts caused by an attack on your systems.

Windows Defender Advanced Threat Protection is a platform designed to help enterprise networks prevent, detect, investigate, and respond to advanced threats.
To help you maximize the effectiveness of the security platform, you can configure individual capabilities that surface in Windows Defender Security Center.
indows Defender ATP uses the following combination of technology built into Windows 10 and Microsoft's robust cloud service:
- **Endpoint behavioral sensors**: Embedded in Windows 10, these sensors
collect and process behavioral signals from the operating system and sends this sensor data to your private, isolated, cloud instance of Windows Defender ATP.
- **Cloud security analytics**: Leveraging big-data, machine-learning, and
unique Microsoft optics across the Windows ecosystem,
enterprise cloud products (such as Office 365), and online assets, behavioral signals
are translated into insights, detections, and recommended responses
to advanced threats.
- **Threat intelligence**: Generated by Microsoft hunters, security teams,
and augmented by threat intelligence provided by partners, threat
intelligence enables Windows Defender ATP to identify attacker
tools, techniques, and procedures, and generate alerts when these
are observed in collected sensor data.
