In Dynamics 365 CRM, it is possible to use the Audit Summary function to retrieve certain data. You are able to retrieve a log of associate/disassociate entities. In other words you're able to see which permissions have been changed and who made the change.
However, this data is unfortunately not exportable, neither in CRM nor in the Microsoft Compliance Center. This would be a great asset for auditing purposes if exporting the data was possible.
