SSH restrictions in Linux environment

Settings of hosts.allow and host.deny in Linux environment

I've set it up for easy local testing in a Linux environment, so I'll keep it for your notes.

/etc/hosts.allow setting

My environment is Cent OS 8 and I set remote access permissions in /etc/hosts.allow. The IP address is 192.168.3.〇〇/24, so I tried to touch not only me but also other people on the same network. The settings are as follows.

sshd : 192.168.3.

/etc/hosts.deny setting

Prohibits SSH connections from all IP addresses except those set in hosts.allow.

sshd : all

Summary

I'm sorry for the small number. Recently I'm also studying Linux.
