ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question

A software team must validate a proprietary binary message protocol used between their IoT gateway and cloud service. They decide to apply generation-based fuzzing rather than mutation-based fuzzing. Which preparatory step is most critical to make the generated fuzz cases both syntactically valid and able to explore boundary conditions of every field?

  • Record a large corpus of real gateway-to-cloud traffic to serve as seed inputs.

  • Add code-level instrumentation so the fuzzer can monitor execution paths during tests.

  • Compile a list of publicly known exploit payloads targeting similar IoT protocols.

  • Create a detailed grammar or schema that describes every field and rule in the binary protocol.
