    How do your protect your internet facing virtualization nodes?

    I'm setting up a dedicated server to host my own virtual servers and I want to know how you protect the host os.

    Thanks!

      Keep track of what's listening on what ports. Use non standard ports. Monitor and log all traffic on those ports. Block brute force attempts. Rate limit problem areas with iptables where it doesn't negatively impact reasonable use. Set up email alerts for every action. Have a remote node monitor system files for changes. Use keys above passwords.

      Relevant packages: fail2ban, iptables, logwatch

    • Jarland's suggestions will help quite a bit, but in practice, a lot of it will be out of your control and you would have to rely on your provider.
