The article is devoted to the issue date of expediting the processing of large data array. The data is presented in memory of cyber systems that are intelligent and involved in the process to ensure the information security of critical facilities. Operation data mining mechanisms based on the use of knowledge bases, accumulating knowledge about the subject area of interest within the framework of tasks.
The explosive nature of the growth in knowledge raises the problem of limiting the amount of data, at the same time the in-processing. Thus, the updated task of changing the availability of knowledge, presented in memory cybersystems providing information security of critical information infrastructure. Attention is drawn to the dynamic nature of the problem, and the fact that similar processes associated with information processing characteristic of the functioning of a constructive mindset and cognitive abilities. It is assumed that the knowledge represented in memory as a set cybersystems partially ordered concepts incorporated within the domain ontology. At the same time updating the knowledge base possible, but by heterogeneous hardware and software modules (sensors) that monitor the outside world, and a team of operators, raising critical information for tasks manually. To change the access to knowledge stored in memory cybersystems providing information security of critical information infrastructure, it is proposed to use the model developed by the association's resource network operates in parallel with the ontology model and spread it on the associative signal. Described model allows to take into account the intensity of the receipt and processing of information (requests), as well as processes of "forgetting" knowledge. The proposed distribution model associative signal associative resource network contributes accounting context when retrieving and interpreting the knowledge presented in memory cybersystems. The totality of these approaches make it possible to realize the knowledge ranking procedure in the memory system according to their level of availability is directly dependent on their relevance, testing and confirmed.
