My problem is that we recently found an unlocked folder whose administrators had assigned 'All Users' connector access on their data sources. The publishers / administrators have a high level of data access, and have published data to server that we are lead to believe was open to connector access to all users for quite some time. Aside from the fact that we clearly need to establish a permissions audit dashboard to ensure this doesn't occur again - we do feel it necessary to do some background research to ensure that none of our user base has accessed or downloaded this data.
Obviously we removed the access as soon as we found out. Is there a way to audit if users connected to or downloaded the exposed data sources?
