FASHION: Functional and Attack graph Secured HybrId Optimization of virtualized Networks. (arXiv:1910.07921v3 [cs.NI] UPDATED)

Maintaining a resilient computer network is a delicate task with conflicting
priorities. Flows should be served while controlling risk due to attackers.
Upon publication of a vulnerability, administrators scramble to manually
mitigate risk while waiting for a patch.

We introduce FASHION: a linear optimizer that balances routing flows with the
security risk posed by these flows. FASHION formalizes routing as a
multi-commodity flow problem with side constraints. FASHION formulates security
using two approximations of risk in a probabilistic attack graph …
