Estimating the informational security level of a typical corporate network

For the general logical and probabilistic models of estimating the success of an attack on a defense object in a typical corporate network, we have obtained and found extreme values of the corresponding analytic expressions for the weights and sensitivity functions in various factors (defense functions). On the example of a typical corporate functions, by using the sensitivity functions formalism, we have obtained risk estimated for certain dangerous events and practical recommendations to increase the level of information security.
