Reverse Engineering- An Introduction

Hi Folks. The two things I'm good at are Programming and Reversing. I already posted few articles here related with Programming.
So I think its time to give something to my another Love as well.     
In this article we will take a look at the concepts and the basic terminology related to Reversing.

What is Reverse Engineering:
  Systematic methodology for analyzing the design of an existing system or device, either as an approach to study the design or as a prerequisite for re-design.

Why Reverse Engineering:
  Every Computer enthusiast is a control-freak. We love to figure out the things in a detailed way. We love to understand the things which are executing behind the Black Box.
We Love challenges that whether a software a really 'unbreakable' or just curious that how a particular project is implemented.
Reversing comes into play while performing any of the above on a software when you actually dont have its source code.

Skill Required for Reversing:

• Experience with tools (hex editor,debugger, disassembler)
• Basic Platform Knowledge(x86)- Stack, Registers etc
• Basic knowledge of Programming like Assembly - win32, PE header etc
• Lots of Patience :)

How to Start:

Quick way:

• Grab some reversing videos and tutorials from internet
• Try repeat the shown steps and reproduce them in your own way
• Keep Learning the new things from internet whenever required.

Good way:

• Read the tutorials about WIN32, AntiDump, import table etc.
• Get a good assembler then and do some practice on assembly.
• Start experience with disassembler and other tools
• Look for some basic Reversing exercises on Google.
• Then you can finally get your hands on some real Stuff with ease.

At the end its only Hard work and Passion which matters.
