Abstract
An extrusion detection system prevents the release of sensitive data from an enterprise. The system includes administration module for broadcasting taint instructions, each of which include a definition of sensitive data. The system also includes a plurality of extrusion detection nodes. Each node marks sensitive data as tainted responsive to the taint instructions, marks data that depends on sensitive data as tainted. When the potential release of tainted data is detected, an action is executed responsive to the taint instructions.
