hello Kiran Saruk

I hope you are doing good. With reference to your query, I would like to tell you that yes you can definately persue diploma in cyber security but I would advise you to dont go with this early . I think you should complete your 12th ,enhance your problem solving skills and then persue a bachelors a degree after which you should go post graudation diploma in Cyber security . This roadmap will benefit you a lot

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