1. Overview
In this tutorial, we’ll learn what reverse engineering means in the computer science field.
2. What Is Reverse Engineering?
Reverse engineering means analyzing a product, software, or system to determine its functionality, design, and specifications. In computer science, reverse engineering includes breaking down a software program into its source code and data structures to understand how it works:
Furthermore, reverse engineering is the opposite of forward engineering, which means creating a program based on requirements and specifications:
3. Reverse Engineering Goals
Reverse engineering can be done for many purposes in computer science. Some of them are:
- To modify a program and make a new and improved version of it
- To find vulnerabilities in a system
- To understand a complex system
4. How Is Reverse Engineering Done?
Reverse engineering typically involves using tools like decompilers (programs that convert an executable program to its original high-level source code) and disassemblers (programs that convert machine language to low-level assembly language).
Analysts then study the results to understand how the software works. In addition, they may also use other tools like debuggers and emulators to test and verify their findings.
5. Conclusion
In this short article, we learned about reverse engineering in the computer science field.
