hello mayurirupavatia

I hope you are doing good. I would like to aware you that the two streams in which you want  to persue btech in have no major difference in course structure. But at the time of placement scernaio I think you will have many options in cse with specialization in cyber security because in this fields you will have many options like to go in machine learning, android development, cloud computing ,etc but in cyber security you will be restricted in that field only

Hope you found this answer helpful. Good luck for your future
