It is a well-known fact that a significant number of Enterprise security breaches happen due to internal threats and Office 365 is no exception to this. And being a cloud environment makes things worse due to access from a variety of locations using a number of different devices. While there may be any number of threat-points in the system, the ones related to users, sharing of users information assets through One Drives, both internal and external, user group memberships, internal sharing of user mailboxes and almost any user related data access are the ones that have the maximum potential to cause security breaches. It is imperative that administrators perform routine scans for such internal threats by performing a security audit related to users in their Office 365 tenants. The personnel in charge of Office 365 Security should document and monitor everything about their Office 365 users – what access rights they have, who the administrators are, what roles have been assigned to Office 365 users, what permissions have been assigned to shared mailboxes, public folders and so on. For the SharePoint Online environment, everything related to permissions assigned on Sites, Lists, List Items, and Site Groups etc. must be documented and monitored regularly.
Since the use of cloud environment has grown and evolved so much in recent times, your Office 365 tenant is likely to be accessed by more people, from more places and platforms like never before. A comprehensive approach is required for the administrators to protect the organization’s information assets in this environment.
