How to ensure that Azure AD user accounts don’t get locked out as a result of brute force attacks?
Brute force attacks can be a serious threat to the security of user accounts in Azure AD. Here are some steps you can take to help prevent these attacks and ensure that Azure AD user accounts don’t get locked out:
- Enforce strong password policies: Implement password policies that require strong passwords with a minimum length, complexity, and expiration period.
- Enable multi-factor authentication: Multi-factor authentication (MFA) adds an extra layer of security to user accounts by requiring users to provide two or more forms of authentication to access their accounts.
- Use conditional access policies: Conditional access policies allow you to control access to Azure AD resources based on specific conditions, such as location, device type, or user group.
- Monitor and review Azure AD sign-in logs: Use Azure AD sign-in logs to monitor and review all sign-ins to your organization’s resources. This can help you detect and respond to potential brute force attacks.
- Use Azure AD Identity Protection: Azure AD Identity Protection provides advanced threat detection and prevention capabilities, including identifying and blocking brute force attacks.
- Limit failed sign-in attempts: Configure policies to limit the number of failed sign-in attempts and automatically lock out users who exceed the limit. This can help prevent brute force attacks from succeeding.
By taking these steps, you can help ensure that Azure AD user accounts are protected against brute force attacks and that your organization’s resources remain secure.
