Assessment of Computer Network Resilience Under Impact of Cyber Attacks on the Basis of Stochastic Networks Conversion

The paper suggests an approach to computer network resilience assessment under exposure of cyber attacks, based on analytical attack modeling using the method of stochastic networks transformations. The network resilience assessment methodology and main stages of the proposed method for analytical modeling of cyber attacks are studied. It is shown how the proposed method can be used to generate the reference analytical model of the computer attack. Experimental evaluation of the proposed method for analytical modeling of attacks and developed methodology for assessing resilience of the network under exposure of cyber attacks showed high adequacy of the obtained results and high efficiency of their calculation.
