Go Security Audit and Fuzzing

Go (golang) is a statically typed and compiled programming language designed by Google. Over the years, it has become a language of choice for developers to build concurrency backend applications while maintaining high performance at scale.

This course teaches you all the prerequisites to understand which kind of vulnerability can be found inside Go code. You will learn how to find low-hanging fruit bugs manually and automatically using different Go auditing tools. You will discover how to use existing Go fuzzing coverage-guided frameworks, triage/debug crashes, and improve your code coverage. Finally, you will discover how to build custom Go fuzzers and implement advanced fuzzing techniques to find in-depth bugs on popular Go packages.

Along this training, students will deal with a lot of hands-on exercises allowing them to internalize concepts and techniques taught in class.
