Options for protecting SSH on Dedicated Servers

 

Filter by IP - We can set up a firewall to filter SSH access to the SSH port by IP.

Change SSH Port - This doesn't prevent access, it just changes the port of access.

Use /etc/hosts.deny and /etc/hosts.allow - Utilize application/system level access settings for access to system services.

Use SSH RSA Keys - Disable password/keyboard-interactive authentication and only allow key access.

We can enable 1 or all options at any time.
