          Deep Dive into Fuzzing

          deep dive into fuzzing

          overview

          Fuzzing is a technique of identifying software vulnerabilities by automated corpus generation. It has produced immense results and attracted a lot of visibility from security researchers and professionals in the industry, today fuzzing can be utilized in various ways which can be incorporated into your secure SDLC to discover vulnerabilities in advance and fix them.

          Finding vulnerabilities in software requires in-depth knowledge of different technology stacks. Modern day software&apss have a huge codebase and may contain vulnerabilities. Manually verifying such vulnerabilities is a tedious task and may not be possible in all cases. This training is designed in such a way that it introduces the concept of fuzzing and vulnerability discovery in software&aps;s covering multiple platforms such as Linux & Windows and triage analysis for those vulnerabilities.

          During this training, attendees would be emulating techniques which would provide a comprehensive understanding of "Crash, Detect & Triage" of fuzzed binaries or software. In "Deep dive into fuzzing" we will be covering a detailed overview of fuzzing and how it can be beneficial to professionals in uncovering security vulnerabilities with a hands-on approach through focus on labs.
