Hii Tarun!
If you want to pursue Ethical Hacking in future, you must have completed class 12th with PCM and computers subject combination. You can go for any course related to these subjects in Bachelor's degree program. Some of the Institutes offering ethical hacking course are-
* Indian school of ethical hacking, Bhubaneswar
* Gujarat forensics science University
* Government Institute of forensic science, aurangabad
Etc.,
Hope this helps.
Good luck!
