Does something like that apply here? in a non gui, I'm not sure how it could. I'm probably over thinking it. In a CLI the only things that are running are those that I type.
This is what sudo does. It's just proactive instead of reactive.

As for someone gaining access to my account, I guess I just need to make sure I have a good password.
Or use a key. Or a key plus a password. Or add another for of two or even three factor authentication.

Make sure you are running fail2ban.

awesome, thanks...

Had to be done

Ubuntu uses the sudo group instead of wheel, for some reason. Just a crazy desire to be non-standard.

Where did wheel come from?

https://en.wiktionary.org/wiki/big_wheel
big wheel (plural big wheels)
(idiomatic) A person with a great deal of power or influence, especially a high-ranking person in an organization. She's a big wheel at IBM. -
LOL - when I think of Big Wheels I think of a three wheeled vehicle for kids...
-
Using @scottalanmiller 's definition, I think of Big Wig, lol. Must be where my southern heritage shows, lol.

Why do so many instructions assume selinux is turned off? Don't you want it enabled to protect you?
That and fail2ban?

Because they are lazy, as are most shops, andn so they just disable it.
Although to be fair, turning it off for an install and enabling again when done is fine. It's running operationally without it that is bad.

OK disable/re-enable fine - but I would think.. there would be some configuration requirements for whatever you installed? i.e. some instructions for said changes to selinux?

Not always. Traditionally MySQL could not install without SELinux being disabled, but once installed you turn it back on and it runs fine.
-
Since only CentOS uses SELinux, I think that a lot of app developers question the value of investing too much time in doing it the "right way" when they can just disable it and move on. Other Linux use different technologies so the time needed to any one of them right can be quite a bit.
-
Did I miss it, or are these directions missing the fact that i need to install apache to make ELK work? I'm guessing that's why I can't connect to Kibana (I've disabled selinux just to make sure it wasn't causing problems).

You certainly need some sort of web server! I thought that DO used NGinx, though.

OK - the instructions do include nginx - though since I'm following a script with little to no actual explanation I had/have no idea what it is.

NGinx has replaced Apache some time ago as the leading web server for UNIX platforms.
