Career

I think the following options will be better than MCA
Through security certifications. There are a multitude of certifications based on the category or field of security. Here are a few to name:
Beginner level:
Certified Ethical Hacker - CEH | EC-Council, provided by EC-Council
CompTIA Security+ Provided by CompTIA
Medium to Advanced Levels:
Offensive Security Certified Professional - Provided by Offensive Security. CompTIA CSA+ Provided by CompTIA CyberSecurity Analyst
Similarly, there's CHFI - Computer Hacking Forensic Investigator Certification [Computer Hacking Forensic Investigator-CHFI | EC-Council] for Candidates interested in Forensics - Provided by EC-Council among many more.
2. The next approach is through attending and trying out CTF events - All about CTF (Capture The Flag). These are the perfect platforms to prove your strength and show your skills in the field of cybersecurity. People learn about computer security in a number of ways, all important. For the sake of argument, let's put these in three categories: reading, building, and doing. [Why Should I Play Capture-the-Flag? ]
A Cyber Capture the Flag exercise typically resides in the last of these three categories: DOING. CTF attempts to model the defend/attack experience. Time pressures bring into sharp focus theoretical lessons. Competitive forces exposes assumptions and flaws in tools and systems constructed in a vacuum.
3. Bug Bounty programme
A bug bounty programme, also called a vulnerability rewards programme (VRP), is a crowdsourcing initiative that rewards individuals for discovering and reporting software bugs. If finding vulnerabilities is your forte, these are for you. Here's one of the sample available list of bug bounty programs: Bug Bounty List | Bugcrowd.

Apply for internships during your Bachelor's degree and get an offer of a full time job when you graduate. Apply for internships or graduate jobs during a Masters in Finance in course. Keep on interning even after you've graduated. Apply during a top MBA. Apply after completing an ACA qualification. Apply after a Ph.D.
7. Apply after time in the army
Banks like J. P. Morgan, Barclays and Goldman Sachs run specialist programs for hiring ex-military veterans. Time in the army isn't a sure-fire route into an investment banking job, but it's definitely an established route in.
8. Apply after time in law
Before he became a trader and worked for Goldman Sachs, Lloyd Blankfein was a lawyer. On Wall Street, law was traditionally a good route into front office investment banking division (IBD) jobs. Robert Kindler, global head of M&A at Morgan Stanley, spent 20 years at US law firm Cravath Swaine & Moore before moving into M&A in 2000, for example.
9. Apply after some time on consulting
Banks hire in outsiders to help them work on strategy. If you're a strategy consultant who specializes in the financial sector, you may be able to get an internal strategy job in an investment bank. Equally, if you've spent time working on regulatory implementation with a consulting firm, you could get a job implementing regulations internally with banks.
10. Apply through your 'network'
okay, networking and nepotism aren't as big as they used to be in investment banking - particularly since the Chinese 'princelings' scandal. But having family, or friends, or alumni, to vouch for you still helps. One of Goldman Sachs' top M&A bankers in the UK is the son of Martin Sorrell, the advertising mogul. Both of his brothers have worked for the firm too. In most cases, however, networking pure and simple won't get you into a big firm - you'll usually have to start at a smaller name and try working your way up. You can also do CFA.
