Microsoft has just announced a number of new security features coming to Office 365.
Advanced Security Alerts
Office 365 will now alert administrators based on unusual behavior such as logging in from a location they have not logged in before or if a user takes unusual administrative actions.
Cloud App Discovery
Office 365 will now allow administrators to monitor use of third party cloud services such as DropBox or Box and to see how they are using these services to manage documents.
Revoke App Permissions
An “Add-In” in Office 365 is granted permissions to access data within the tenant based on the business user deploying the add-in. Administrators will now see a dashboard that shows all the apps and provide a centralized management function so that access can be revoked by the administrator if the add-in is not sanctioned.
