Reverse Engineering is a process where, a researcher gathers the technical data necessary for the documentation of the operation of a technology or component of a system. With the help of this research method researchers are able to examine the strength of the softwares, applications, systems etc. and identify their weaknesses in terms of performance, security, and interoperability. The reverse engineering process allows researchers to understand both how a program works and also what aspects of the program contribute to its not working. Independent manufacturers can participate in a competitive market that rewards the improvements made on dominant products.

For example, there are lot of vendors who does the security audits like ‘Sedulity Solutions & Technologies’, which allow users of software to better protect their systems and networks by revealing security flaws, which ultimately require reverse engineering. The creation of better designs and the interoperability of existing products often begin with Reverse Engineering.

Reverse engineering is taking apart an object to see how it works in order to duplicate or enhance the object. The practice, taken from older industries, is now frequently used on computer hardware and software. Software reverse engineering involves reversing a program's machine code (the string of 0s and 1s that are sent to the logic processor) back into the source code that it was written in, using program language statements.

Reverse engineering can be viewed as the process of analyzing a system to:

1. Identify the system's components and their interrelationships
2. Create representations of the system in another form or a higher level of abstraction
3. Create the physical representation of that system

Reverse engineering is the general process of analyzing a technology specifically to ascertain, how it was designed or how it operates. This kind of inquiry engages individuals in a constructive learning process about the operation of systems and products. Reverse engineering as a method, is not confined to any particular purpose, However it is often an important part of the scientific method and technological development. The process of taking something apart and revealing the way in which it works is often an effective way to learn how to build a technology or make improvements to it.
