Hello Sarath!

You can pursue M.Tech Information Security after completing your B.E in Cse Course. There is no issue as B.E is almost equivalent to B.tech. Pursue M.tech only if you want to study the subjects in depth and research on it. 

Hope that helps!

hi sarath,

 yes you definitely can study information security after b.e in cse. for being in cse background it will definitely give you some advantage. even many non cse and it background candidate now opted mtech in information security due to increasing demand of security analyst in indian IT field. you can apply through gate or there are many institute like birla institute of technology, iiits offer mtech on information security.
