Just think about it…

• Most utilities’ industrial infrastructure consists of legacy equipment originally designed to be safeguarded from unsecured networks by perimeter protection such as firewalls.
• But firewalls offer little or no protection against attacks (such as malware on removable devices) originating within the industrial network itself.
• Many traditional security tools cannot be applied to an industrial environment, can actually harm the devices that control plant equipment, and even using them for scanning can cause major plant disruption.
