- ufw allow proto tcp from xxx.xxx.0.0/xxx.xxx.255.255 to any port 22
- The /24 at the end of the address is the network mask, in CIDR notation. You can look up netmask calculators to figure out what it means, but basically /24 means a netmask of 255.255.255.0

"아직 발경되지 않는 버퍼 오버플로우 취약점데 의해서 해킹 당할 수 있습니다. Nginx를 압단에 둠으로써 이런 취약점에 의해서 해킹을 완전히 막아주지는 않지만, 저는 Nginx를 Proxy서버로써 앞단에 두는 것이 좋다고 생각합니다."
