The UK's National Cyber Security Centre recently issued a blunt warning to government and industry alike, warning that many systems are now connected "in ways their designers never anticipated", built on protocols never intended to withstand the sophistication of today's attackers.
That warning applies to all organizations relying on cross-domain processes to move data between environments with different security levels, and especially to complex cyber-physical systems where data flows between standard IT and operational technology (OT) assets.
