No. Most colleges students are free to come and go. Basically, you keep yourself safe similar to living anywhere.
I went to a very large university, campus was huge, so we had our own police, plus there were emergency phones along the walking paths. I don’t even know if they still have those phones. When I was in college in the 1990’s I vaguely remember guests had to sign in if they came into my dorm at night. I’d be surprised if that’s still the case. My dorm was co-ed and we had people stay over all of the time.
Basic rules: Buddy system! Walk with your head up, know you’re surroundings. Have someone expect you if you are walking alone who will know you are late. Don’t get drunk! If you drink, make sure you are with a friend who will not leave you alone who is not getting drunk. That’s the buddy system again.
Use “find my” with friends and family if you have an apple phone.
Overall, I felt safe on my campus. There was almost always other people walking around and doors were often open in the dorm halls. That was one of the great things living on campus, friends around all of the time.
