Continuous Access Evaluation (CAE) is supported by core Microsoft 365 workloads like Exchange Online, SharePoint Online, and Teams, and the reach of CAE is gradually spreading throughout the Microsoft cloud ecosystem. However, security researchers report inconsistent coverage across first-party apps and clients that take a little gloss off the promise of instant access revocation when critical events like user password changes happen.
A Technical Community post discusses the topic of using the Entra ID continuous access evaluation (CAE) feature to revoke access for service principals when apps become risky or potentially compromised. The Microsoft Graph Command Line Tools app is a good example of a service principal in common use, so we examine the access tokens issued for interactive Graph sessions to discover if they are CAE-enabled. Just for fun!
The Microsoft 365 admin center will support continuous access evaluation (CAE) from September 2024 to help revoke access from accounts more quickly when critical events happen (like an account password being changed). Adding CAE support to an admin center is always a good idea, but it shouldn’t take away from the need to protect Microsoft 365 accounts with multifactor authentication. Stop compromise before you need to react to compromise!
On January 10, Microsoft announced that the base Office 365 workloads support Continuous Access Evaluation (CAE) for critical Azure AD events like password changes or account deletions. Although you can take CAE even further with conditional access policies, giving Exchange Online, SharePoint Online, and Teams the ability to react to critical events in almost real-time is a very big thing indeed.
