Dear, As mentioned by you - Information security and Cyber Forensics course is under Department of computer Science and Engineering is a post graduate programme offered by Dr. M. G. R. Educational and Research Institute eligibility of which is B.E/ B.Tech (CSE, ECE, EEE, IT), /M.Sc. CS IT) /M. CA. So, after completion of your MCA you can pursue for the same. Best wishes.

For Paper 01- Arihant can help in a good way. When it comes to the Subject Book - Mass Communication - Trueman, Arihant, Atlantic and even Upkar can be used. The issue is that the syllabus is too vast that we need to have 2 books to ensure good coverage.

The easiest way to complete CS is immediately after 12th. Then it would have taken 3 years and would have completed with your graduation. Do upvote and follow me, in case I was of any help. Thanks.
