Computers & IT (Non-Engg)

You are advised to do basic courses on computers fundamentals including hardware concepts, then you may go for various CISCO certification to have career in networking with an aim to be a CCNA.

Some universities allow BCA graduates for M.Sc. in CS. You may look at target universities eligibility criteria to plan your education. You can also evaluate lateral entry MCA.

With pure B.Sc. in mathematics it will be difficult to get job in IT companies. You are advised to either do MCA or few PG Diplomas to seek job in IT companies.

MBA IT is to prepare students for business development roles in IT companies not for technical roles. To be an ethical hacker, you require strong system programing skills. If CEH provides you strong skills, then even without MBA, you can be an ethical hacker.

Ethical hacking means hacking something without breaking any rule or doing hacking for good purpose, and not stealing data from someone.
For cyber security, you should have the knowledge of hacking, so that you can stop a hacker from doing bad things. You need to find the digital footprint of the hackers to stop and catch them.

If you want to be ethical hacker then you can join DRDO.
If you won't than there are some requirement in Intelligence Buero department for the computer specialist and they will train you for ethical hacking.
Also, police hires computer specialist for IT forensic cell.
If you want to pursue some course then I would suggest you to visit website of Forensic University, Gandhinagar.
This university is Gov. University and also trains police officer for forensic cell.
