USR - G - Require strong auth
This page describes the configuration of policies for Conditional Access within Microsoft Entra ID associated with systems built according to the guidance provided by ASD's Blueprint for Secure Cloud.
Estimated reading time: 3 minutes
Instruction
The below tables outline the as built configuration for ASD’s Blueprint for Secure Cloud (the Blueprint) for the Microsoft Entra admin portal at the following URL:
https://entra.microsoft.com/#view/Microsoft_AAD_ConditionalAccess/ConditionalAccessBlade/~/Policies
The settings described on these pages provide a baseline implementation for a system configured using the Blueprint. Any implementation implied by these pages should not be considered as prescriptive as to how an organisation must scope, build, document, or assess a system.
Implementation of the guidance provided by the Blueprint will differ depending on an organisation’s operating context and organisational culture. Organisations should implement the Blueprint in alignment with their existing change management, business processes and frameworks.
Placeholders such as <ORGANISATION.GOV.AU>, <BLUEPRINT.GOV.AU> and <TENANT-NAME> should be replaced with the relevant details as required.
Caution
In order to meet ASD Essential Eight Maturity Level 2 requirements, this policy has been updated to use an Authentication Strength that enforces the use of phishing-resistant MFA methods. This excludes the use of number matching push notifications in Microsoft Authenticator as was previously documented.
The use of passkeys with Microsoft Authenticator is in public preview.
Before implementing these settings, organisations should continue to ensure that any settings meet their operational and security requirements.
