Abstract

A key issue in assessing the security state of a complex computer network is determining its connectivity, in some detail. For example, NERC-CIP audit requirements in the electric power grid requires utilities to identify and document all connections that are possible to devices whose operations are essential to proper delivery of power system services. Failure to comply with NERC-CIP requirements can (and has) led to very large fines. In this talk we describe the challenges and a solution wherein the configuration files of firewalls, switches, and routers are used to build a model where all connectivity permitted by the configurations can be computed. We go further to address a problem of performing that analysis in the cloud, as a service, on an anonymized transformation of the model which ensures that sensitive IP map information does not touch the cloud (even in encrypted form), but still the same connectivity results are discovered and reported as with the un-anonymized model.
