Design recovery is the most vital subset of reverse engineering because in which knowledge of the domain, external (or) outer side information, and deduction or fuzzy reasoning are added to the investigated (or) subjected system to find the high level abstract of the system, normally which is not obtained by directly observing the system. Reverse engineering involves a very broad range of aspects such as starting from the existing implementation, recreating or recapturing the design ideas, and extracts the actual requirements of the existing system. Reverse engineering in and of itself doesn’t mean changing the subsystem or developing the new system based on the existing. The important contents like data formats, algorithms that the programmer used to implement the software, and ideas of the programmer (or) company will be revealed to the 3rd person by violating the security and privacy issues using reverse engineering technique. But now it is frequently used on computer hardware and software. Generally, this reverse engineering will take place in older industries on machines. ![]() Software reverse engineering is done to get the source code of the program because to know how the particular parts of the program perform particular operations to improve the program functionality or to fix the bugs in the program or to find the malicious block of statements in the software if any. Software reverse engineering is a technique that converts a machine code of a program (string 0’s and 1’s usually sent to the logic processor) back into the programmable language statements which are called source code. And enhance the components of the system and improve the performance and scalability of the system (or) subsystem. ![]() ![]() ![]() Reverse engineering is the process of understanding the particular aspects of the program, which are listed below to identify the components of the system and the interrelationship between the components.
