1. A method comprising: monitoring one or more processes executing on one or more processing devices of an enterprise to identify operations performed by the one or more processes, the operations comprising at least one of file system operations and data transport operations associated with one or more data files stored in one or more storage devices across a communication network of the enterprise; storing attributes of the file system operations and the data transport operations in graph node data structures, each of the graph node data structures comprising one of a source node representing a source file or a source network connection, a destination node representing a destination file or a destination network connection, and an operator node representing a given one of the one or more processes; identifying one or more correlations, each of the one or more correlations correlating one or more of the file system operations with one or more of the data transport operations for a given process; generating one or more edge nodes representing the one or more correlations, a given edge node representing a relationship between one of the source nodes, one of the destination nodes and one of the operator nodes for a given one of the correlations; and rendering a representation of the graph node data structures on a display, the representation comprising graphical representations of the graph node data structures graphically linked by graphical representations of the one or more edge nodes, the graphical representation of a given one of the edge nodes depicting a weight indicating a level of suspicious behavior associated with at least one of one or more of the file system operations and one or more of the data transport operations represented by a given one of the source nodes, a given one of the destination nodes and a given one of the operator nodes connected by the given edge node for the given correlation; wherein the method is performed by at least one processing device comprising a processor coupled to a memory.
