Disable PermitRootLogin, PasswordAuthentication, and KbdInteractiveAuthentication in sshd_config to enforce key-only SSH access. This prevents brute force attacks on VMs exposed via autossh tunnels through the SSH bridge.

Broaden epel-release from redhat_7/centos_7 only to all redhat/centos platforms. This is needed to install fail2ban (and potentially other EPEL packages) on RHEL 8/9/10. Signed-off-by: Lars Erik Wik <lars.erik.wik@northern.tech> Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Install fail2ban on Debian/Ubuntu and RHEL/CentOS platforms to ban IPs with repeated failed SSH auth attempts. Configures sshd jail with 5 max retries, 1 hour ban time, and 10 minute find window.

There was a problem hiding this comment.
yes, I really think we need a refined sshd config module though... as still managing just sshd_config is not really sufficient. If some of these options are present in sshd_config.d they may come in first and "win". So we need to compare the RESULTING configuration aka ssh -G output which shows the resulting configuration.
