Mettere in sicurezza l’accesso SSH su un server DirectAdmin è semplice utilizzando CSF (ConfigServer Security & Firewall).

Basta seguire questi due passaggi:

  • Aggiungere gli indirizzi IP dai quali si vuole consentire l’accesso SSH nel file di whitelist (csf.allow)

  • Rimuovere la porta SSH dall’elenco TCP_IN nel file di configurazione csf.conf

In questo modo, l’accesso SSH verrà bloccato per tutti gli IP tranne quelli espressamente autorizzati.
