Computers & IT (Non-Engg)

Hello Himanshu,
Here are few good colleges for MCA:
1.Pune University Computer Science Department
2.School of Computer and Systems Sciences (Jawaharlal Nehru University)
3.School of Computer and Information Sciences (University of Hyderabad)
4.National Institute of Technology Tiruchirappalli (Department of Computer Applications)
5.BIT Mesra Department of Computer Science and Engineering
6.Department of Mathematics and Computational Sciences (NIT Surathkal)
7.Motilal Nehru National institute of Technology
8.PSG College of Technology
9.NIT Rourkela
10.ITM University
11. VIT University

There is no such specialisation called cyber security existing in B.Tech and I hope you are aware engineering is a stream and B.Tech is a subject offered in this stream.

The eligibility criteria for doing BCA is 10+2 with maths as a subject in majority of Universities. Some Universities such as IGNOU or Symbiosis University, etc. allow non-maths students also to do BCA. Admission in BCA is based on entrance examinations. You may refer to following link for list of top BCA colleges in India:

IGNOU is a central university and degrees awarded by University are valid for higher studies and job. BCA by distance learning from IGNOU is a good option.

The cyber security experts are needed by private and government IT. If you are an expert in cyber security then you don't need to worry about your job and the package of a cyber security expert is 6 LPA (minimum) in an IT company but in the government organisation, the package is low in starting but after some time the give you a huge raise or maybe you can get a high package in the starting.
