Correction of sensitive configurations

Creation of the custom configuration file

NOTE

It is important not to save these changes directly in the main configuration file (/etc/ssh/ssh_config or /etc/ssh/sshd_config). This is because any update to the OpenSSH package will overwrite the main file and delete your custom configurations.

sudo nano /etc/ssh/ssh_config.d/hardening.conf
