Dear Aspirant,

There are two options One that you can do specialization in ethical hacking from colleges which offer these courses .Many colleges like srm and other institutes offer these courses.

And other options is by taking computer science in college you can take various courses from udemy and other platforms .

And then you can be certified ethical hacker.If you devote your important time to ethical hacking and try to learn from core then you can easily make career in this.

Thanks

All the very best
