These defaults are more secure than the baseline policies.

Immediate MFA protection for “privileged” Azure AD actions via the Azure Resource Manager API (such as Azure Portal Access, Azure PowerShell and the Azure CLI).

Legacy authentication will be blocked, restricting access from older clients, like Office 2010, IMAP, POP3, SMTP, ActiveSync clients that don’t support Modern Auth, and traditional methods of managing Exchange Online using Remote PowerShell.

Multi-Factor authentication for administrators and end-users, required within 14 days of the next sign-in after enablement.

Security Defaults enforces these settings:

This is a change, as although per-user MFA could be enabled in Office 365, it didn’t include the Authenticator app, nor the straightforward enablement mechanism enjoyed by Conditional Access or service-wide Azure MFA. Security Defaults replace Baseline Conditional Access policies, which do a similar job, and are offered free to all Office 365 subscriptions, whether or not you’ve paid for Azure AD Premium licensing. This does mean that many, may Office 365 tenants are vulnerable to a number of attack vectors, including password spray attacks, because an attacker can repeatedly try and login to an Office 365 tenant using basic scripting to attempt a login, then if they successfully authenticate with a username and password, there isn’t an MFA mechanism in place. But the default settings for an Office 365 tenant have been aimed at the lowest common denominator – organizations with legacy clients and with an expectation that organizations will buy add-on security features, like EM+S if they truly want security.

They aren’t appropriate for everyone, but if you’ve not enabled multi-factor authentication yet, or haven’t disabled legacy authentication, then this might want to be something you consider.Įvery Office 365 environment should be secure, and technically – they aren’t susceptible to vulnerabilities, are patched and up to date and regularly tested. Azure AD Security Defaults arrived recently and make it easier to implement some of the most common security settings in your Azure AD directory, and Office 365 environment.
