Comment on Thoughts on crowdsec
EncryptKeeper@lemmy.world 2 weeks agoHow would it, or any software for that matter determine a given request is malicious before it does something malicious?
Crowdsec does it by using crowd-sourced blocklists (hence the name). So if an IP triggers a scenario on other machines, that malicious address will be proactively added to your blocklist before it ever gets a chance to impact your machine.
That is the big advantage of crowdsec over reactive-only solutions, like fail2ban.
Yes, that is the hard part. But it can be done. Geoip blocking like only allow your country - blocking every China or Russian user etc. If you are selfhosting home and worry about your SSH access, then you can do a lot of things to block then early. It is all about authentication. Lets say you require VPN access in - example Wireguard. You could also do “port knocking” but that is not encrypted. You could require the user first has to be authenticated somewhere else, like require first Microsoft login and only then your ip is allowed.
