What is baseline protection?
In the last year, identity attacks have increased by 300%. To protect your environment from the ever-increasing attacks, Azure Active Directory (Azure AD) introduces a new feature called baseline protection. Baseline protection is a set of predefined conditional access policies. The goal of these policies is to ensure that you have at least the baseline level of security enabled in all editions of Azure AD.
This article provides you with an overview of baseline protection in Azure Active Directory.
Require MFA for admins
Users with access to privileged accounts have unrestricted access to your environment. Due to the power these accounts have, you should treat them with special care. One common method to improve the protection of privileged accounts is to require a stronger form of account verification when they are used to sign-in. In Azure Active Directory, you can get a stronger account verification by requiring multi-factor authentication (MFA).
Require MFA for admins is a baseline policy that requires MFA for the following directory roles:
- Global administrator
- SharePoint administrator
- Exchange administrator
- Conditional access administrator
- Security administrator
- Helpdesk administrator / Password administrator
- Billing administrator
- User administrator
This baseline policy provides you with the option to exclude users. You might want to exclude one emergency-access administrative account to ensure you are not locked out of the tenant.
Enable a baseline policy
To enable a baseline policy:
Sign in to the Azure portal as global administrator, security administrator, or conditional access administrator.
In the Azure portal, on the left navbar, click Azure Active Directory.
On the Azure Active Directory page, in the Security section, click Conditional access.
In the list of policies, click a policy that starts with Baseline policy:.
To enable the policy, click Use policy immediately.
What you should know
While managing custom conditional access policies requires an Azure AD Premium license, baseline policies are available in all editions of Azure AD.
The directory roles that are included in the baseline policy are the most privileged Azure AD roles.
If you have privileged accounts that are used in your scripts, you should replace them with managed identities for Azure resources or service principals with certificates. As a temporary workaround, you can exclude specific user accounts from the baseline policy.
Baseline policies apply to legacy authentication flows like POP, IMAP, older Office desktop client.
