Secure my VPS
Hi. I do have a VPS that i would like to secure it. All i need is a script that has the rules:
-to block all connections to any port apart from port 1194 udp
-Block specific IP ranges, xxx/8
-block specific IP, yyy/32
-more than 3 attempts to ssh in a minute, then blacklist for 24 hours.
the system is a Debian 8.
