3. • You understand admin consent!
• You know how to provide API consent for applications
• You know how to block end-user consent

6. What is Application Consent?

Admins must consent to apps that require
broader permissions
Admins can consent on behalf of all users in an
organization

10. What I will be talking about….
Protecting data!

11. What I will be talking about….
KnowBe4's Chief Hacking Officer Kevin Mitnick called me with some chilling news. A white hat hacker friend of his
developed a working "ransomcloud" strain, which encrypts cloud email accounts like Office 365 in real-time. My
first thought was :"Holy $#!+".

14. Notes on V1 vs V2 Endpoint
This presentation focuses on the AAD V1 endpoint and the associated application, consent,
and permissions model
There are some key differences to be aware of with consent on V2:
• Support for Dynamic/Incremental consent
• New URL paths including separate admin consent endpoint
• Applications registered at apps.dev.microsoft.com as opposed to portal.azure.com

https://docs.microsoft.com/en-us/azure/active-directory/develop/active-directory-v2-limitations
https://docs.microsoft.com/en-us/azure/active-directory/develop/active-directory-appmodel-v2-overview

15. Endpoint v1 Runtime – When is consent prompted for?
The most common scenario:
• The first time using a application that requires access to personal or
organizational resources
Some scenarios that may not be expected:
• The set of permissions required by the application have changed
• Consent was revoked after being granted initially
• The application is using incremental and dynamic consent to request additional
permissions after consent was initially granted. This is often used when optional
features of an application additional require permissions beyond those required
for baseline functionality.

16. Introducing MSAL (Microsoft Authentication Library)

18. Azure AD Applications
• Single tenant application
• App for users in a single organization
• Admin or user registers app in directory tenant
• Sign in at: https://login.windows.net/contoso.com/<protocol>
• Multi-tenant application
• App for users in multiple organizations
• Admin or USER registers app in developer’s directory tenant
• Admin configures application to be multi-tenant
• Sign in at: https://login.windows.net/common/<protocol>
• User prompted to consent based on permissions required by application
• Consent registers application in user’s tenant

20. Manageability – Common challenges
 Where did this application come from
I have no idea how Susie got assigned
no idea what power
These need not be mysteries any longer

21. Manageability – Common challenges
 What happens in the admin view when someone consents
what permissions an application has
what consented applications are assigned
revoke a consent grant
request administrator-level consent
control how consent works

22. Manageability – Common challenges
 What happens in the admin view when someone consents
what permissions an application has
what consented applications are assigned
revoke a consent grant
request administrator-level consent
control how consent works
