Yup, /etc/securetty is the go-to for secure terminals.

It's definitely /etc/securetty for root login.

I’m leaning towards /etc/securetty too, but I wonder if there are any other files that could affect root login.

I’m a bit confused about this one. I know /etc/services is related to network services, but I can't recall what the others do.

I feel like I've seen a similar question before, and I think /etc/securetty was the right file to configure root login access.

I think the answer might be /etc/securetty, but I'm not completely sure. I remember it has something to do with secure terminals.

Wait, what's the difference between current logging details and data source inventory? I'm a little confused on that part. I'll have to review my notes to make sure I understand.

I remember discussing how oil prices directly affect operating costs for airlines, so that might be a threat, too.

I'm not sure about the specific APIs, but I remember something about using them for communication between layers. Maybe the northbound and southbound APIs?
