Hi aspirant

If you are interested in cyber security or information security then you should go for Ethical hacking course .

This is for CSE students who have knowledge of computer networks, programming languages.

If you are from CS background it will be quiet easier for you else you will face lots of difficulty.

You can join online platform for learning ethical hacking like udemy,coursera,udacity,internshala.com etc. 

Hope this was helpful.
