Fuzzing

Fuzzing or fuzz testing is an automated software testing technique that involves providing invalid, unexpected, or random data as inputs to a computer program. The program is then monitored for exceptions such as crashes, failing built-in code assertions, or potential memory leaks.

SPIKE

SPIKE is a protocol fuzzer creation kit. It provides an API that allows a user to create their own fuzzers for network based protocols using the C++ programming language. The tool defines a number of primitives that it makes available to C coders, which allows it to construct fuzzed messages called “SPIKES” that can be sent to a network service …
