Abstract:
In this paper we describe a mathematical apparatus and software implementation of a module of the RiskPanel system, aimed to compare computer-security knowledge learned from various online sources.
To describe this process, we use model-theoretic formalism. The knowledge of a particular computer attack obtained from the same source is formalized as an underdetermined algebraic system, which we call a generalized case. The knowledge base is a set of generalized cases. To implement the knowledge comparison, we construct a generalized fuzzy model, the product of all algebraic systems stored in the database.
We consider an algorithm for computing consistent truth values and describe a software implementation of the developed methods. The developed algorithm has polynomial complexity.
