Software Reverse Engineering:

Introduction

Reverse engineering is the process of changing the code language into a simpler level without changing the original program. The process involves recreating the software program’s binary code to be able to trace back to the original source code. This is mainly done to enhance the features of the product and to fix given bugs. In the software reverse engineering, the high level language is interpreted to a level that that the machine can interpret very fast.

Tools used in reverse engineering

For the reverse engineering to be done, there are certain tools that are mandatory to be put in place. These tools have specific tools functions. The tools are debuggers, disassemblers, hex editors and PE and Resource Viewer.

1. Debuggers is used to set breakpoints while editing the assembly code at the run time. This is achieved as the debuggers expands the functionality of the dissemblers supporting the CPU registers.
2. Hex Editors Enables the binary to be viewed by the editor and then changes the binary’s function to match the programming of the software.
3. Dissemblers I used to extracts, both the imported and exported functions. Most importantly, it is used to convert the binary code into assembly code.
4. PE and Resource Viewer the design of the binary code enables it run on windows based on machines having a specific data showing how to set up and initialize a programme.the programs running on the windows should have portable executable (PE) supporting the DLLs which the programs can borrow.

Importance of Reverse Engineering to the Technology

Reverse engineering is used in software security. The use of reverse engineering in programming is to ensure that the systems are not susceptible any serious security faults. That is making the systems strong and preventing hackers and spywares from accessing it.This has promoted ethical hacking whereby an individual hacks into the system to find out if the system is still susceptible to hacking or spywares.

Reverse engineering enables developers to be able to add or remove features without knowing the source code. Moreover, the developers are able to use very many techniques to incorporate new features into the existing software.

Software engineering is used to in software setting. In the virus study and analysis, most of the viruses normally don’t leave instructions on how they wrote the code and what they were set to accomplish. Reverse software Engineering has made this study and analysis to be very possible and easy.

Conclusion

Having Reverse Software Engineering knowledge is very important especially with the current technology. The use of the knowledge has at least minimized the case of hackers who interfere with very sensitive information. Though RSE is interesting, it require very vast knowledge and for one to get accredited to do this must highly qualified. The qualified personnel should be assigned to work in areas having sensitive information to prevent issues like hacking.
