Hi B Giri

As you have clearly mentioned the term CEH, It seems that you are having the basic knowledge and interest in computers, programming, networks,... 

Several certification courses are available in both online and as well as in hands-on.

But it is much important to decide about where to do such certification.

I've just googled it and came to know about some of those certifications and their links are here...

Dear Bhuvnesh,

In order to become a certified ethical hacker you should have IT knowledge.

You should be aware of the programming languages C , C++  and Java.

There are certified ethical hacker course which you can do or you can also go for CSE to become a ethical hacker.

Good Luck!!
