The security risks of network connectivity include malware intrusion into servers and sabotage such as denial-of-service attacks. It will be shown here how these security risks can, in contrast to employing firewalls, effectively be coped with by an adequate network interface whose architecture combines two malware-proof programmable controllers with specific software functions. By design and physical separation, the interface behaves in a fail-secure way, i.e. there is never open access from a network to a computer even if the interface fails itself.
