Ways to harden Ubuntu 18.04 Server
I am running an Ubuntu 18.04.2 web server, and am looking for ways to harden it against attacks and others. I know this may be broad; I do not wish to add a question for every possible aspect
I've googled around and found little advice on this
Some limitations:
SSH keys are difficult/impossible to use on Android(my primary device) because permissions are not manageable on unrooted device and AWS require the key to not be public viewable. If someone know how to edit the permission correctly on Android with no root, please let me know
I refuse to lock the root account- try entering your 32 randomized character password 3 times in as many minutes. For me, it's just not worth it having multiple accounts on one server(root enabled by default)

I will vote to close this question as it is too broad. And for root password, a good security practice is to have a 128 randomized character password and to write that on a pize of paper that is put into a sealed envelope into the bank valve and only used in an emergency. Add a user account and add it to the sudoers group.

You can use SSH keys on Android. Any server with password based authentication exposed to the Internet is a ticking time bomb.

You can't use keys last I tried; the permission can't be set on a non rooted drvice and the keys won't work without certain permission (not public viewable).At least with an AWS server

Too broad a question? What should I do, ask a separate question for each of the many possible aspects? Also, tried the sudoers thing-muss the part about re-entering my password?
