Fail2ban (home SSH/web)
Bans abusive IPs hitting SSH/web services on self-hosted home servers.
Authorized testing only. Practice on systems you own, isolated labs, or targets with written permission. Unauthorized access is illegal.
When
You expose any self-hosted service (even via reverse proxy).
How
Enable jails for sshd/nginx; tune findtime/maxretry; monitor bans.
Why
Stops credential noise from becoming a successful brute force.
Commands & usage
sudo apt install fail2ban
sudo systemctl enable --now fail2ban
sudo fail2ban-client status sshd
Commands are educational examples. Adapt hosts, paths, and rates to your authorized scope.
