Just as the guidance on creating and maintaining a definitive view of OT architecture aimed to give you the visibility to inform decisions, the new secure connectivity principles aim to help you take actions. By systematically applying these principles to all connections – whether new, revised, or existing – you can reduce your attack surface, improve incident response options, and maintain the trust and safety of your operations.
The stronger your connectivity design, the harder it becomes for adversaries to cause disruption – whether their target is your data, your process, or the critical services your OT supports. We encourage OT owners, operators, integrators, and vendors to put these principles into practice.
