Primary objectives

  1. Design a protocol fuzzing campaign
  2. Instrument targets for crash detection
  3. Triage and de-duplicate findings
  4. Integrate fuzzing into a validation pipeline

Overview

What This Lab Is For

Fuzzing finds the defects that review and manual testing do not. This lab builds the capability as a repeatable programme rather than a one-off campaign — designed scope, instrumented targets, triage that survives hundreds of findings and evidence in a format a type-approval assessor will accept.

Build and operate fuzzing campaigns against automotive protocol stacks, with instrumentation, triage and defect reporting that fits a validation programme.

Learning goals

  • Operate a repeatable automotive fuzzing programme
  • Produce evidence that satisfies validation requirements

Technology stack

  • UDS
  • DoIP
  • SOME/IP
  • CAN
  • Coverage instrumentation

Tools used

Hardware, Software and Security Tooling

Production-representative equipment and the toolchains engineers use on the job — not simulators standing in for them.

  • Hardware

    Physical targets and instrumentation you will work on directly.

    • Instrumented target ECUCoverage-instrumented build for crash detection
    • DoIP and Automotive Ethernet benchRig
    • Debug probe for crash captureDebugger

  • Security tools

    Analysis, testing and cryptographic tooling applied to the targets.

    • Protocol fuzzing framework
    • Target instrumentation harness
    • Crash triage tooling

Common questions

AutoSec Fuzz Testing Lab FAQ

What engineers and their managers ask before booking lab time.

Do I need prior fuzzing experience?
No. The lab starts from campaign design principles. It does assume embedded or validation engineering background — you should be comfortable instrumenting a target and reading a crash dump.
Why is instrumentation emphasised so heavily?
Because an uninstrumented target survives faults silently. A campaign that runs for a week and reports nothing usually means the harness could not detect a failure, not that the stack is sound.
Does the lab cover CI integration?
Yes, in the final exercise. You leave with a gating model, a triage workflow that de-duplicates at scale and an evidence format that fits an existing validation process.
