Tutorial / Cram Notes
Password protection in Azure AD helps prevent users from choosing weak or commonly used passwords that can easily be guessed or cracked by attackers. This is achieved by maintaining a global banned password list that Microsoft updates based on the analysis of current cyber threats. Organizations can also create custom banned password lists tailored to their company’s needs.
Azure AD Password Protection Policies
There are two layers of protection offered:
- Azure AD Global Banned Passwords: This default feature ensures that user-chosen passwords are not within the most commonly attacked passwords globally.
- Custom Banned Passwords List: Organizations can define an additional list of words or patterns that are specific to the company, such as brand names or industry-specific terms, which will be rejected in user passwords.
To implement custom banned passwords, administrators can navigate to the Azure AD portal, select “Security,” then “Authentication methods,” and finally “Password protection.” Within this setting, they can define the custom banned list.
Example of Password Protection Implementation:
Suppose you want to prevent users in your organization from using the company name “Contoso” in their passwords. You can add “Contoso” to your custom banned passwords list. If a user tries to set their password to “Contoso123,” Azure AD will enforce the password protection policy and reject the password.
Smart Lockout
Smart lockout in Azure AD is designed to lock out potential attackers while letting legitimate users access their accounts. It achieves this by recognizing sign-in attempts that are likely from legitimate users and only locking out the attackers.
Smart Lockout Settings
The following settings can be managed in Azure AD for smart lockout:
- Lockout Threshold: Number of failed sign-in attempts permitted before a lockout.
- Lockout Duration: Length of time in minutes for which an account is locked out.
Administrators can configure smart lockout settings by going to Azure AD portal, selecting “Security,” then “Authentication methods,” and “Password protection.” In this section, smart lockout settings can be adjusted.
Example of Smart Lockout Implementation:
An organization might set a lockout threshold of 10 and then choose a lockout duration of 5 minutes. This means after 10 unsuccessful login attempts, the account is locked, preventing further login attempts by the attacker, but will not be a significant disruption to a genuine user who might have made a mistake remembering the password.
Comparison
Feature | Password Protection | Smart Lockout |
---|---|---|
Objective | Prevent weak password usage | Limit the effectiveness of brute force attacks |
Customization | Global and custom banned lists | Threshold and duration settings |
User Experience | Users must choose stronger passwords | Legitimate users less likely to be locked out |
Protection Level | At the time of password creation/change | During the sign-in attempt |
In conclusion, password protection and smart lockout are essential features in Azure AD that contribute to safeguarding the identity and access pipeline within an organization. Administering these settings effectively not only helps to protect the organization from external threats but also teaches users the importance of strong password hygiene. For the Microsoft Identity and Access Administrator, mastery of these settings is a must, and application of these features is a key skill evaluated by the SC-300 exam.
