Hi There,

A little background about you would have been better for me to guide you, but never the less let me begin by making a brief introduction

As such, please note that these days Privacy and security are playing a major role. Every second business needs to be well secured fro their competitors. Just by being confided in a locker, is not the only way to be safe. This keeping the data secured through ethical hacking is an in ting now.
Businessmen hire professional hackers to code important files and documents. Though there are misuses too.
As such Ethical Hacking course is open to anyone. There are some institutes that provide online training too, though I would recommend practical learning than virtual learning

I also feel a background of computers especially someone familiar with Computer languages, operating systems, technical aspects, stands a better chance to understand the hacking course and would be able to learn quicker.
So someone with an IT qualification or a BCA graduate or a Computer science graduate would understand and find this course useful.

In-case you are not from a computer background, then it is highly recommended before you join the hacking course, get yourself a computer language and programming certificate.

As such one of the world renowned institutes for this course is Ankit fadia. Check, www.ankitfadia.in

Hope this helps.
Wish you good luck...
