Hi! The seminar is part of a program at UCLA called Undergraduate Student Initiated Education (USIE); it is specifically for undergraduate students who want to teach a 1 unit seminar. I have personally taken an upper division CS course on cybersecurity at UCLA, and my professor is my faculty mentor!
Teaching something is a great way of reinforcing the material for yourself, since to end up having to conceptualize the material in a few different ways to meet your students at their own level of understanding. I think it's cool that UCLA is giving undergraduates that opportunity.
