What is Fuzzing: The Poet, the Courier, and The Oracle
Fuzzing is well established as an excellent technique for locating vulnerabilities in software. The basic premise is to deliver intentionally malformed input to target software and detect failure. A complete fuzzer has three components. A poet creates the malformed inputs or test cases. A courier delivers test cases to the target software. Finally, an oracle detects if a failure has occurred in the target. Fuzzing is a crucial tool in software vulnerability management, both for organizations that build software as well as organizations that use software.
Synopsys solutions help deliver a more comprehensive security offering for the SDLC by adding black box testing capabilities, including the Codenomicon Defensics® tool for file and protocol fuzz testing, and the Codenomicon AppCheck™ tool for software composition analysis and vulnerability assessment.
