  • 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
