On the issue of assessing stability of functioning of communication network elements
The article considers the issues of assessing stability of power grid functioning to destructive destabilizing influences (DDI). The proposed method represents an attacked telecommunication network as dynamic hyper network that allow objective assessing an attacked network state in the context of stability. The author introduces a concept of DDI and the related concept of a DDI channel that affects NE elements of a communication network at different levels of hyper network models. Simplicity and convenience of representing an attacked network in the form of dynamic hyper networks makes it possible to extend the class of problems related to determining stability of communication networks to external destructive influences, in particular, to find correlation links between private intruder models, attack models and vulnerability models of a power grid at the investigated level. Such approach allows designing stable communication networks taking into account dynamically changing external factors connected with threats directed to a communication network structure. It also allows effective detecting and blocking threats related to external information influences while ensuring accessibility, integrity, confidentiality of user information. Due to the proposed approaches, it seems appropriate to create knowledge ontologies based on a network response to DDI at network monitoring points, which in turn will effectively design and install information protection tools in real network structures. The author proposes a private mathematical model of external destabilizing influence, which is based on the probability theory. It makes it possible to trace dynamic changes in a network structure and determine quantitative estimates of QoS applications.
