Control: 1.1.2 Ensure that 'Multi-Factor Auth Status' is 'Enabled' for all Privileged Users

Description

Enable multi-factor authentication for all roles, groups, and users that have write access or permissions to Azure resources. These include custom created objects or built-in roles such as;

• Service Co-Administrators
• Subscription Owners
• Contributors

Multi-factor authentication requires an individual to present a minimum of two separate forms of authentication before access is granted. Multi-factor authentication provides additional assurance that the individual attempting to gain access is who they claim to be. With multi-factor authentication, an attacker would need to compromise at least two different authentication mechanisms, increasing the difficulty of compromise and thus reducing the risk.

Remediation

Other Options within Azure Portal

Follow Microsoft Azure documentation and enable multi-factor authentication in your environment. https://docs.microsoft.com/en-us/azure/active-directory/authentication/tutorial-enableazure-mfa Enabling and configuring MFA with conditional access policy is a multi-step process. Here are some additional resources on the process within Azure AD to enable multifactor authentication for users within your subscriptions with conditional access policy.

Please note that at the time of writing, there is no API, Azure CLI or Powershell mechanism available to programmatically conduct security assessment or remediation for this recommendation. The only option is MSOL.

Default Value

By default, multi-factor authentication is disabled for all users.
