I used boringproxy for years and I recomend you

Check “boring proxy” On github easy to install and configure and does https for you

Avoid Docker as much as possible. It gives you a quick way to run apps, but in a way that you can’t see what is going to be installed.

It is also double resource heater.

And it has many frequent vulnerabilities.

trough ssh when you connect to your machine run :

lastb -10

This will show you the last 10 login failed attemps you can change to 20 or whatever

you can also run: last -10 to see the last successful logged in

use :

more history

to see all the commands that someone have typed

on the dir /var/logs you have a lot of another logs too

for more paranoid level use

netstat -a

This will show you all incoming and outgoing communications

and like the others said considere using firewall and fail2ban

Note: don’t relly to much on firewalls since they are easy to bypass

keep all softwares updated

read frequently about new vulnerabilities if there is some vulnerability that affects your software until gets patched turn of that service.

when you say some services on your network are you talking about machines or softwares?

for machines yes ups makes sense for softwares writing some scripts to run on start up should be enough another alternative can be setting up wake on Lan that way you can bring all up again wherever you are

you can just use a reverse shell

again and again … docker is becoming a joke

Well i do that with termux just import the keys to android

Why people try to find another software alternatives instead of the use of the best and practice:

The GPG!

Works flawless for years.
