Ethical hackers are specialised cyber security experts who work for all organizations which have an internet presence and use extensive use of web technologies for business. Ethical hackers role is a proactive one as they prevent cyber- crimes and protect cyber space from intrusion. They ensure data security and protect computer systems from illegal hacking activities. Computer hackers use their expertise in computing and knowledge of programming, web applications, operating systems, assembly language, internet security systems, etc., to protect computer systems from illegal hackers.
It is a niche skill and has limited career opportunities. However, if you can break into your first job then its is very high paying and respected job. Most of the computer hackers have graduation degrees such as B.Tech CSE/IT, BCA-MCA, B.Sc CS. Most of the hackers are those who have excellent programming skills.
You can appear in professional certification examination to become a Certified Ethical Hacker (CEH) by appearing in the examination conducted by ED-Council. Certification is achieved by taking the CEH examination after having either attended training at an Accredited Training Center (ATC) or completed self-study. CEH is a skilled professional who understands and knows how to look for weaknesses and vulnerabilities in target systems and uses the same knowledge and tools as a malicious hacker, but in a lawful and legitimate manner to assess the security posture of a target system. The CEH credential certifies individuals in the specific network security discipline of ethical hacking from a vendor-neutral perspective.

BBA stands for Bachelor of Business Administration & BCA stands for Bachelor of Computer Applications.
Both these courses are Graduation level courses. The duration of the both the courses is 3 years.
BCA course is technical oriented where in variety of computer related subjects or technical subjects that the candidate is going to study and thereby he is going to have good number of job opportunities in various IT companies soon after the completion of BCA course.
BBA involves variety of subjects which are related to business and management oriented. These people can have job opportunities in all the business sectors.
My sincere suggestion is don't look for job opportunities soon after the completion of your Graduation whether it is BBA or BCA.
Because, you will not be paid more if you join in a job through Graduation as the highest academic qualification and in addition to this, the work load will be more.
In some companies, hard core working activities will be allotted to these new joinees who join soon after the completion of their Graduation.
I suggest you to choose the stream which you are interested between BBA and BCA and try to get admission for the respective course in a good college.
If you join BCA, then you can go for MCA, MBA course later. In contrast to this, if you join BBA, then you can go for MBA course. You can grab better job in MBA & do MBA in top B schools like IIMs, XLRI, FMS, SP Jain, IIFT, TISS, (MA HRM & LR), MDI, etc.
If you say scope then MCA will have more scope. But interested in managing field & if you do ultimately MBA then BBA is for you otherwise MCA.
