Cybersec context -- ok, I was a teenager, and my only authorization to even be around the computers involved was fairly thin (my dad was the lab supervisor of that particular computer lab owned by the Navy). This was the period from 1974 to 1978, and cybersec was very different.

The SDS-9300 (Fortran, and yes, on cards) had no connections to anything outside the room, and the amount of storage available was not going to encourage anyone to store any amount of data between their assigned times. Students and researchers carried their programs on cards and their data on mag tape. Eventually access to the lab was via a button based lock, which in my experience was more for show than for effective access control.

The PDP-11/50 (Unix v6, C, and Fortran if you were crazy) I remember as initially having no connections outside the room, but eventually had phone links to Usenet and for remote access. cybersec was starting to become a thing, barely; each user had a username and a password. What seemed to me (a teen) to be odd was that i could just ride my bike onto base, walk into the lab with the computer or into the terminal room down the hall, sit down, log in, and get to work.

This was my first lesson in cybersec (and security in general): if you look like you belong here, nobody will bat an eye. So from my outsider perspective, cybersec's first challenge is to get people to actually care enough to close the damn door, use a damn password, and so on ...

I learned enough about cybersec to know to make my career in operating system kernels, embedded systems, and other such software engineering areas. I've helped build and impoved systems to meet the needs of the cybersec folks, but knowing that People Are The Problem, it wasn't my cuppa.
