What it checks

Security defaults provide a baseline set of identity security mechanisms including MFA registration requirements, MFA challenges for administrators, and blocking legacy authentication. Organizations using Conditional Access policies should have security defaults disabled to avoid conflicts, but tenants without Conditional Access that also have security defaults disabled have no baseline protection against common identity attacks. This check verifies that either security defaults or equivalent Conditional Access policies are actively protecting the tenant.

Recommended value

Security defaults enabled for tenants without Conditional Access. For tenants with Conditional Access, security defaults disabled with equivalent or stronger CA policies in place

Remediation

Check whether security defaults are enabled in Entra ID > Properties > Manage security defaults. If security defaults are disabled, verify that Conditional Access policies provide equivalent or stronger protection including MFA for all users, legacy authentication blocking, and MFA for administrative actions. If neither security defaults nor equivalent Conditional Access policies are in place, enable security defaults immediately as a baseline protection measure.
