CODE COVERAGE-BASED TAINT PERIMETER DETECTION

摘要

A code coverage-based taint perimeter detection system and method for testing software code by determining code coverage and detecting new coverage of the code. Embodiments of the system and method perform tainted data flow analysis on execution traces of the code to determine tainted branch targets. The tainted branch targets may be filtered to remove any tainted branch targets that have already been covered. New coverage can be determined by monitoring the filtered tainted branch targets, which in some embodiments involves the use of software breakpoints that are automatically placed at the locations in the tainted branch targets at runtime. Embodiments of the system and method use an iterative process to ensure that only tainted branch targets that have not already been covered or tested are examined.
