The entirety of the course is student centric, hands on, and lab intensive. On day one, students will be instructed on the use of the Peach Fuzzing Platform, from a practitioner's perspective, learning the ways in which Peach can be used to fuzz a variety of targets including network protocol parsers, ActiveX/COM interfaces, file parsers, APIs, and web services. Students will also be introduced to new methods by which fuzzing can be utilized to locate security flaws not typically considered detectable by fuzzing, including N-tier applications.

On the second day, students will be exposed to the internals of Peach for a developer's perspective. The Peach architecture and module interfaces will be explained in great detail as to equip students with the skills necessary to extend and adapt Peach to their custom needs. Students will then develop their own Peach extensions in a lab environment to reinforce these concepts.

Upon completion of this course, students will be enabled to create effective fuzzers that target:

  • State-aware network protocol parsers
  • N-tier applications
  • Arbitrary APIs
  • File parsers
  • COM and Active/X components
  • Detect non-classic faults in software
  • Extend the Peach Fuzzing Platform by creating custom Transformers, Generators, Publishers, and Monitors.
  • Apply these concepts and tools to their unique environment
  • Utilize parallel fuzzing to increase fuzzing efficiency
