Abstract
Methods and systems are described for detecting command injection attacks. A positive, taint inference method includes receiving signature fragments on one hand, converting command injection instructions into command fragments on another hand, thus identifying potential attacks upon the condition that a command injection instruction includes critical untrusted parts by using signature fragments. A system detects command injection attacks using this kind of method, and remediates and rejects potential attacks.
