Hello There,

When speaking of Cyber expert, what exactly d you mean????

It can be either A Cyber crime personnel, forensic expert, or Ethical hacking.

As such to pursue Forensic sciences, one needs to be from the science background.

Now then we could focus on Ethical Hacking.
Any Corporate or business man needs their information to be well secured and protected from their competitors
Here is where Ethical hacking comes in place.
An ethical hacker not only helps protects corporate functioning by protecting their data, but they also help in various cyber crime issue investigations.

As such one can pursue this course simultaneously with any other course. So you could pursue it with your Graduation too. But better would be to fut finish your Graduation, since this is your final and the most crucial year which will define your career in future.
Although there are few Institutes that provide a virtual system of learning, whereby you do not have to attend a classroom setup to learn, but I would advise you to avoid these courses.
Since this is a course that requires more of a Practical means or hands on learning and just learning it virtually will not help.

Please note that though this course is open to all, but still someone with good knowledge regarding software and computer languages will find this course easier than compared to someone who is not familiar with computers.

When thinking about Ethical Hacking, the first name that ne can think of is Ankit Fadia

Hope this helps.
Wish you good luck.....
