Abstract
A method of determining suitable insertion points for inserting string sanitizers in a computer code is provided herein. The method includes the following stages: obtaining: (i) a computer code associated with a data flow of externally supplied data, from one or more sources to one or more sinks, (ii) locations of the sources, and (iii) locations of the sinks; building a graph representing control paths, data paths and semantic relationships between the control paths and the data paths of the computer code; associating all tainted data paths on the graph, being data paths that go from sources to sinks and do not include a sanitizer; and determining, on the tainted data paths, potential control paths suitable for sanitizer insertion.
