Reverse engineering is the process of looking over a system to create an understanding of its functionalities, behavior, and its structure. It is performed on the software, hardware and firmware. Reverse engineering allows the user to analyze the code and generate a blueprint of the system. The blueprint can be used to recreate the software, hardware or firmware. Reverse engineering is performed to gain insight into a system that is already in place, or to create a similar system for personal or commercial purposes. Reverse engineering is also performed as an aid during the software development lifecycle. It is used to identify shortcomings, bugs and errors in software. It is also used to gain an in-depth understanding of the system and its functionality in order to improve the system and software.
You can learn reverse engineering in various ways. You can do a course in RE by self paced online courses, boot camps, institutes or from online educational sites.
There are three types of Reverse Engineering are there:-
Hardware Reverse Engineering: It is a form of cyber-reverse engineering that involves assembling, reassembling, or disassembling the hardware device to its core. Example - For reconstructing or repairing faulty mobile phones, laptops etc., need support in a cyber security investigation or research.
Network Reverse Engineering: It is either extracting or restructuring the network environment to understand its deductive functioning like Network Protocol Reversing. For example - cyber security professionals are expected to possess network-to-reverse engineering skills to recreate or restructure a network environment for their investigation.
Software Reverse engineering: It is the practice of examining a software system either in whole or part to extract design and implementation information. For example - to detect, determine and neutralize the functionality of viruses and malware.
Basically, Reverse engineering is a Restructuring i.e.
The transformation of one representation to another at the same level is called restructuring.
Requirements → Design → Source Codes → Behaviors
Reverse Engineering -
Behaviors → Source Codes → Design → Requirements
Design Recovery: reproducing all the information for understanding the system re-documentation.
Providing different views of the system Reverse engineering
The first phase - Understanding the system
The second phase - forward engineering
The conclusion of Reverse engineering is a new research area in software maintenance. Understanding the program and recovering the information from the system is the most critical subset of Reverse engineering.
