Azure Active Directory (Azure AD) password protection is a feature that enhances security by preventing users from creating weak or easily guessable passwords, which are vulnerable to attack. This is crucial for maintaining the integrity of an organization’s security posture.
Understanding Azure AD Password Protection
Azure AD Password Protection includes two main components: password policy enforcement and banned password lists. With these tools, an organization can prevent users from choosing passwords that are too simple or that have been compromised in previous data breaches.
Password Policy Enforcement
Azure AD has a default password policy that applies to all users in a tenant. The policy defines password complexity requirements which typically include minimum length and a mix of characters (uppercase, lowercase, numbers, and symbols).
Banned Password List
In addition to complexity requirements, Azure AD maintains a global banned password list, which contains commonly used weak passwords that are easy for attackers to guess. Admins can also add to this list with a custom banned password list specific to their organization.
Implementing Azure AD Password Protection
To implement Azure AD Password Protection, follow these steps:
- Enable Azure AD Password Protection on the Tenant-Level:
Navigate to the Azure portal, go to the Azure Active Directory section, and find the ‘Password protection’ settings. From here, you can enable or disable password protection for the tenant.
- Configure Custom Banned Passwords:
Under the same settings, you can specify a list of custom banned passwords for your organization. These should include passwords specific to your organization that could be easily guessed, such as the company name or industry-related terms.
- Set Password Protection for Windows Server Active Directory (On-Premises):
Azure AD password protection can be extended to on-premises Active Directory instances. You need to install Azure AD Password Protection Proxy and the Azure AD Password Protection DC Agent on your on-premises Active Directory domain controllers.
- Enforce the Policy:
Policies will start to take effect upon the next password change or user sign-up event. Ensure that all users and admins are informed about the new policies so they understand the requirements for creating passwords.
Managing Azure AD Password Protection
Once implemented, Azure AD Password Protection requires ongoing management to ensure it remains effective:
- Monitor Banned Password Hits:
Keep an eye on the logs to see if users are attempting to use banned passwords. This could indicate a need for user education or policy adjustment.
- Update the Custom Banned Password List:
Regularly review and update the list to account for new trends in password attacks or organizational changes.
- Educate Users:
Provide training to users about the importance of strong passwords and how to create them within the constraints of the password policy.
- Review Password Protection Reports:
Utilize Azure AD’s reporting features to track the effectiveness of the password protection measures and identify areas for improvement.
Examples:
Here’s an example of how your custom banned password list might look for a fictitious company, Contoso.
| Contoso’s Custom Banned Passwords |
|---|
| Contoso123 |
| Password@Contoso |
| Contoso#2023 |
| WelcomeContoso! |
| Summer2023 |
Users trying to use any of these passwords would be prompted to choose a different password when signing up for an account or changing their current password.
In conclusion, implementing and managing Azure AD password protection is an essential step in securing your organization’s identity infrastructure. By configuring and maintaining password policies with Azure AD’s built-in and customizable features, an organization can defend against password-related attacks and promote better security hygiene among its users. This plays a critical role in the broader scope of compliance and security governance, relevant to the MS-100 Microsoft 365 Identity and Services exam and the professional management of identity services.
