Overview What You Will Learn Curriculum Instructor

Course Overview

Reverse engineering is an important concept that requires someone to take something apart, dissect it, and put it back together again. This technique is used to learn how something works and gain an intimate knowledge of its innermost workings. Unfortunately, the topic of reverse engineering in a Linux environment hasn’t received enough attention from software creators, security consultants, and the cybersecurity community. Originally, the reverse engineering process was used strictly on hardware, but it is now an important part of software engineering, malware identification and analysis, exploitation development, and forensic investigations.  Moreover, reverse engineering is an integral part of creating secure software and computing environments for organizations and anyone who uses electronic devices.  Likewise, it is a vital asset to cybersecurity engineers and allows you to safeguard data, intellectual property, and the protection of assets.

This course will you a unique understanding and familiarization of reverse engineering Linux 32-bit applications with the intended purpose of developing exploits and locating security flaws. We will set up a lab environment that can be used to dissect and analyze software flaws. Furthermore, you will learn how to take this information and leverage it to perform exploitation techniques. The exploitation techniques covered in this class will be buffer overflows, heap overflows, kernel flaws and section overflows, and format string flaws. While going through these topics the students will gain a better understanding of automation techniques using scripting languages and applications. Furthermore, you will learn to use specialized software debuggers, fuzzers, and exploitation frameworks like Metasploit.  

Upon completion of this course, you will be able to understand, identify and leverage these techniques to develop exploits and perform quality control analysis on software applications. Equally important, the student will learn the fundamentals of assembly language and can use these techniques for offensive security, and as an incident responder to identify and analyze attack techniques. The techniques learned in this course will be vital to a successful career in cybersecurity and enable students to confidently perform at the leading edge of cyber defense.
