Security Warnings

Hello!

I am new to all this vps/linux stuff, but already learning!

My question may be silly, so here it goes:

Is there a way to be warned of any security treats, attacks, etc when they happen? I mean, when something goes wrong with the firewall or someone is trying to hack it, i want to be notified of that, so i won’t need to check the server status every hour xD

Thanks for your attention!!
