[xister]

Ich kann nur jedem Admin "fail2ban" empfehlen.
Es ist einfach ein must-have Programm.

[BeNe]

Wie xister sagt - Fail2ban wurde hier schon helfen.
Ansonsten den SSH Port verschieben, root sperren, auf Key-Auth umstellen.
Dann sollte ebenfalls ruhe sein und bist sicherer unterwegs.

Ansonsten kannst auch OpenVPN installieren und SSH + alle anderen Dienste die die wünschst von der external IP lösen so das Du nur noch local per VPN Tunnel drauf kommst. Der Dienst ist von extern dann überhaupt nicht mehr erreichbar
