Msc Cybersecurity - dissertation ideas ( something that can be done in 3 or less months)

Hello all! Im currently in my final semester of Msc Cybersecurity and have to submit a dissertation in 3 months. I'm very bad at researching ( not that I havent done or lazy to do), I usually get overwhelmed and my mind goes crazy. Im here to get guidance or advice on what is doable and what isn't.
