Abstract

Data loss prevention systems and methods begin protecting data upon the creation of the data. One such method involves detecting a file system operation targeting data on a storage device. The file system operation creates or modifies the data or a set of permissions associated with the data. In response to detecting the file system operation, the method prevents unauthorized access to the data. The method begins preventing unauthorized access after the detection of the file system operation and before any subsequent read access to the data via the file system.
