Hi aspirant

If you are from SC/ST/OBC then definately you can get.But if you are general category then you should look for some other college.

Mtech in CS information security has low cut than CSE but still it may happen you will not get.Sometimes it depends on the number of seats available and number of students are applying for the same course and at that time cut off may go high or may come back to low.It is all about the chance.

You should apply for it .
