Abstract: The disclosed computer-implemented method for protecting sensitive data against data loss may include (1) identifying a resource comprising sensitive data, (2) establishing, for the resource, an accessibility threshold that indicates a limit on permissions to access the resource, (3) monitoring how the permissions to access the resource drift over time by tracking changes in users' permissions to access the resource, (4) detecting, while tracking the changes in users' permissions to access the resource, that access to the resource has surpassed the accessibility threshold, and (5) in response to detecting that the access to the resource has surpassed the accessibility threshold, performing a security action to protect the sensitive data from potentially being exposed. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: File management systems and methods are presented. In one embodiment, implementation of a method for determining the accurate ownership of a file within a data system includes: identifying a first plurality of access events for a file, wherein the file is associated with a directory of related files; identifying a second plurality of access events for the related files within the directory, wherein access events in the first and second plurality of access events occur within a period; determining a pool of users accessing files within the directory within the period; and selecting a user from the pool of users as an inferred owner of the file based on access metrics related to the plurality of access events.
