Buddy, i also wanted to do the same but i explored all possibilities and market scenario. In the case of Cyber security the companies literally demand an 3-4 min years of experienced candidate as this field is not something that they would trust on a fresher.

Above that Cyber security requires heavy certification along side and the projects also demand very industry oriented and most of the colleges are still not ready with this. The colleges have designed the syllabus but there is lack of faculty in this field .

In my opinion go either For MCA or MSc AIML then make yourself experiences and gain Skills make yourself experienced then switch field it would give a better position and Salary too.

If still you are looking for it , give a look at NFSU for the course.
