Microsoft Rolling Out New Azure Active Directory Certificate Policy This Month

Microsoft plans to increase its Azure Active Directory certificate update pace, with the next rollover happening on Oct. 10.

The updated certificates are needed to secure application access to Microsoft's Azure AD identity and access management service, which taps Microsoft's datacenter infrastructure (also known as "the cloud"). Microsoft's practice has been to update these security certificates about every six weeks or so. However, new plans, announced this week, indicate that the certificates will undergo more frequent updating, going forward.

Moreover, Microsoft now prefers using the term "global signing keys" instead of "certificates" for Azure AD.

"Continuing on our commitment to protect our customer's data and building on the momentum of this August 15, 2016 rollover, we will be increasing the frequency with which we roll over Azure Active Directory's global signing keys (previously referred to as "the Azure Active Directory certificates")," Microsoft's announcement indicated.

Microsoft's last certificate update happened on Aug. 15, and got announced back in July. However, Microsoft is now planning to change its announcement policy. Instead of giving notice to organizations about the coming certificate changes, Microsoft is planning to update these global signing keys without giving notice.

The certificate updates, also called "rollovers" by Microsoft, won't be a problem for applications that already have an automatic update process built into them. Microsoft considers all applications in the Azure AD App Gallery to meet this requirement, including the custom apps that are housed there. Moreover, all apps housed on premises that get published via Application Proxy or that use the Azure AD B2C service meet the automatic rollover criteria.

While Microsoft's new practice will be to not give notice when certificate rollovers happen, it still wants to know about any certificate update-associated problems.

"If you experience unusual behaviors please contact Azure Support," Microsoft's announcement stated.
