NVAT - Network Vulnerability Analysis Toolset

bullet

The overall goal of our approach is to formulate a theoretical basis for constructing global metrics that can be used to analyze and proactively manage the impact and recover from complex network faults/attacks.

Analogous to the biological systems that use ecological metrics such as temperature or blood pressure to quantify the health state of an organism, we introduce a novel Abnormality Distance (AD) metric to quantify the network system states (e.g. normal, uncertain, and abnormal). The basic principle of using network abnormality attribute is shown in the figure below, in which the network states are determined through online monitoring of whether the AD is over the normal operational thresholds. This provides the mathematical basis to proactively respond to faults/attacks in real time.
