Harden SSH.
SSH is the front door to your server, and every public box gets its handle rattled around the clock. Pick your settings and get a hardened sshd_config — key-only auth, no root login, limited attempts — with the safe commands to apply it.
sshd -t to validate before reload.The door everyone tries
You don't have to imagine attacks on SSH; just tail the auth log on any public server and watch the login attempts roll in from around the world, every minute, forever. They're automated, they're relentless, and they're cheap to defeat: require a key instead of a password and the brute force has nothing to brute. Add no-root-login and a couple of limits and the front door goes from constantly-tried to effectively closed.
SSH hardening protects host access. Once the host is ready, operating the applications on it is a separate job: deploying updates, keeping processes running, checking health, and recovering a service when it fails.
Harden the host. Operate the backend.
Infraveil deploys and supervises managed services on servers you control, with health checks, gateway traffic policy, and recovery controls in one place. Keep SSH configuration and host-access monitoring in your infrastructure runbook; the control plane does not replace that responsibility.
