An evolved lens for critical infrastructure security

[via CI Security] “The National Critical Functions construct provides a risk management approach that focuses on better understanding the functions that an entity enables or to which it contributes, rather than focusing on a static sector-specific or asset world view. This more holistic approach is better at capturing cross-cutting risks and associated dependencies that may have cascading impact within and across sectors. It also allows for a new way to view criticality, which is linked to the specific parts of an entity that contribute to critical functions. By viewing risk through a functional lens, we can ultimately add resilience and harden systems across the critical infrastructure ecosystem in a more targeted, prioritized, and strategic manner.”
