Yeah, the stories and concepts I was reading about are in The Art of Human Hacking by Christopher Hadnagy. He goes into so much detail, but it seems like a lot of this stuff is overkill in literally almost every situation. It seems like, after some thought, and reading some of your guys' descriptions, all you have to know how to do is not say anything blatantly suspicious and not be an asshole and you can get in anywhere you want. It seems like this book applies only to cases where you're trying to break into an actually secured facility. Based on the detail and meticulous methodology, the facility would likely have to be owned by an intelligence agency for this book not to be a waste.
Hell, speaking of school security, I'm on the University of Cincinnati campus all the time, and as long as you're not black (Think Dubose-Tensing case) and there are no sports events going on, you can pretty much go wherever, say whatever, and do whatever you want. When the school isn't in use, literally every building and every room is essentially open to the public. There are no restrictions, and no one is ever checking anyone's access. There are more UC police officers patrolling the surrounding black neighborhoods than there are on the campus itself. I don't know what makes your students so important that they require a dedicated security system, but they've made it clear that they don't give a shit about the safety of students here

And the DORM "Security Measures?" Shit's student-run. Some snobby math major sits at a desk by the front door 2 days out of the week and
maybe asks to see your Driver's license (What the fuck does that even do exactly? "YOU CAN GO AHEAD. YOUR FACE MATCHES THIS PICTURE YOU HANDED ME.") when she's not scrolling Facebook on her laptop or complaining of boredom to her friend on the phone. (Hypothetical individual, it's not the same person every time.)
This country's security is run by failures at every level in every industry. Makes me even more excited to enter the security industry. Any advice on where to start? What college courses you recommend or suggest I avoid?
