Firewalls are the problem with DMZ designs. Many practitioners have the mistaken impression that firewalls protect industrial systems while still providing access to industrial data. In fact, firewalls do not provide access to data, they provide access to systems. In fact firewalls do not provide access to data – they provide access to systems. This access can be used to attack PI servers and other systems in DMZs, right through the firewalls. This eBook digs deeper into these problems and suggests an alternative: Waterfall’s hardware-enforced Unidirectional Security Gateways. The gateways make strong security simple, providing access to industrial data without providing access to industrial systems. Download our eBook now to learn how your security program can be simplified and strengthened.
