Assessing compromises of data security is achieved by establishing access control policies for data files in storage devices across an enterprise. A list is compiled of the data files that were accessed by processes executing on processors of the enterprise. A suspicion score is assigned to each of the processes based on deviations of in-memory behaviors of the processes from established criteria. In response to the suspicion score meeting a suspicious process criterion, the file system operations performed by the suspicious process are analyzed against the access control policies and the suspicion score is modified based on a degree to which the file system operations performed by the suspicious process violate the access control policies.
