You can pursue your Ethical Hacking course along with your B.Sc (CS) also because there is only diploma and certification courses available for the same and to become a professional hacker you require motivation, dedication, initiative, self-education and formal training in ethical hacking. I would like to suggest a few points:- 1. Know about the different types of hackers, such as White Hat, Grey Hat and Black Hat hackers

2. Evaluate your potential and interests and gain some programming knowledge such as C, or Java.

3. Learn the UNIX operating system as it is regarded as the original operating system built by hackers.
