We will look at how to create and maintain a solid and effective Active Directory password policy in this article via Group Policy. Before we move further, let’s briefly take a look at Group Policy and Group Policy Object (GPO).

First and foremost, what exactly is Group Policy? Group Policy is a Windows feature that enables a wide range of advanced settings that network administrators can use to control the working environment of Active Directory users and computer accounts. It essentially provides a centralized location for administrators to manage and configure the settings of operating systems, applications, and users.

When used correctly, Group Policies can help you increase the security of user computers and defend against both insider threats and external attacks. Let’ understand what Group Policy Object is:

A Group Policy Object (GPO) is a collection of settings created with the Group Policy Editor in the Microsoft Management Console (MMC). GPOs can be linked to single or multiple Active Directory containers, such as sites, domains, or organizational units (OUs). Users can use the MMC to create GPOs that define registry-based policies, security options, software installation, and other features.

How to Create Active Directory Password Policy via GPO

Organizations require a strong Active Directory password policy to defend against the various attacks techniques stated above.

Password policies define various rules for password creation, such as minimum length, complexity details (such as whether a special character is required), and the length of time the password must be  used before it can be changed.

The Default Domain Policy is a Group Policy Object (GPO) that contains settings that apply to all domain objects. Admins can use the Group Policy Management Console to view and configure a domain password policy (GPMC). Expand the Domains folder, select the domain from which you want to access the policy, and then select Group Policy Objects.

To implement the password policy, take the following steps:

Step 1 – Navigate to the Default Domain Policy folder by searching for Administrative Tools from the search bar.

Here, we are going to define the policy for minimum password length. As we can see from the screenshot above, the default minimum password length is 7 characters.

To do so, double-click on the minimum password length and change the number to your desired character. Note: the maximum number for setting minimum password length can’t go beyond 14 characters.
