Cybersecurity--operational resilience of computer networks

Abstract:

A plurality of communicatively coupled, networked assets may be threatened or attacked by a cybersecurity attack. The operational resiliency of the computer network determines whether the cybersecurity attack leads to a shutdown of one or more assets, or even the entire computer network. A cybersecurity server selectively restricts and controls the data flow over the network and transforms a configurable, networked asset from a low, medium, and high cybersecurity mode. The cybersecurity server may reside on a firewall device or other networked device, and adjusts the cybersecurity mode based on a criticality score that measures the operational resiliency of the computer network. The criticality score changes as cybersecurity threats or attacks are identified and as mitigation strategies are implemented on the networked assets.
