Don't use defaultports for all services.
Install and configure fail2ban to deny attacks and iptables to block ips

man iptables

Code: Alles auswählen

iptables -I INPUT -s 10.10.10.10 -j REJECT #IP Block
iptables -D INPUT -s 10.10.10.10 -j REJECT #Block deaktivate
e.g.

Code: Alles auswählen

iptables –A INPUT –s 8.0.0.0/8 –j REJECT
blocking ip 8.x.x.x

Code: Alles auswählen

iptables –A INPUT –s 8.8.0.0/16 –j REJECT
blocking ip 8.8.x.x

Code: Alles auswählen

iptables –A INPUT –s 8.8.8.0/24 –j REJECT
blocking ip 8.8.8.x
