Is Cyber Security a good topic to talk about for a personal statement?

I’m thinking of making cyber security my main topic for my personal statement as I am doing a written project for a summer school on it and I’ve done some virtual work experience on it too. I’m also thinking of doing it on cyber security because I feel like AI, machine learning and software development is kind of over saturated and everyone is going to base theirs on those topics. Is cyber security a good topic to talk about and will top universities (e.g Oxbridge, Imperial, UCL etc) appreciate it
