MODEL OF THE ATTACKER'S INFLUENCE ON A FRAGMENT OF TRANSPORT COMMUNICATION NETWORK BASED ON THE CARRIER ETHERNET TECHNOLOGY

Abstract

The transport communication network plays a key role in ensuring the transfer of traffic between access nodes. At the same time, modern Carrier Ethernet network technology, which implements a number of mechanisms for monitoring and managing the state of the transport communication network fragments, does not have built-in protection mechanisms against the targeted attack of the attacker on the communication network. In this regard, the task associated with the evaluation of the probability-time characteristics of the attacker's attack on the transport communication network, functioning on the basis of Carrier Ethernet technology, is actualized. The article examines the functioning of the Сarrier Еthernet transport network in terms of the impact on the computer-style attack "Substitution of the trusted object." A block diagram of the algorithm of the computer attack of this type will be revealed, as well as its mathematical model developed taking into account the profile model of the attack and the method of topological transformation of stochastic networks.
