How to protect Home Assistant against hackers

alerts and decisions are empty.
No active decisions and No active alerts

But on my HA i saw today this alert

Login attempt failed
Login attempt or request with invalid authentication from vmi2464809.contaboserver.net (5.104.83.47). See the log for details.

Does that mean that crowdsec did not block that attacker but simply my password holds?
And unfortunately i dont knwo how to scan my system from extern. Is a portscanner enough? Like checking open ports from Open Port Check Tool - Test Port Forwarding on Your Router ?

Well, CrowdSec cannot block every IP failing a login only once. Technically, it can if you want it to, but that would be dangerous. Instead, if I recall, it will block if 10 logins fail within a minute.

And if your password can be found in less than 10 attempts, well it’s digital Darwinism in a way :slight_smile:

Okay so i assume i am protected :slight_smile:
hehe

i wanted to install the homeassistant logs (got the hint from here) How to protect Home Assistant against hackers - #6 by bigbang but it tells me

cscli parsers install crowdsecurity/home-assistant-logs
Nothing to do.

What does this mean “Nothing to do”?

It means that you done everything by yourself.
