Home / AISecuring a server using AIBy Flavio CopesSep 15, 2026I asked Codex to audit a freshly migrated Ubuntu server. It enabled the firewall, hardened SSH and Apache, removed installer files, applied 124 security updates and rebooted. Here is what it found and what I learned.~~~I know nothing about security, except that there’s always someone who knows more than you.
