DEVELOPMENT OF INTELLECTUAL SYSTEM PREVENTING LEAKAGE OF PROTECTED INFORMATION USING KNOWLEDGE BASES
The article deals with the problem of increasing the efficiency of the control and prevention of leakage of confidential information circulating within the organization, and in cooperation with the information networks of general use through the development of intelligent system of pragmatic identification of confidential information. The main purpose of this system is to develop early detection, prevention and localization (minimization) of the risks associated with violation of the order of processing, storage and transmission of confidential information. The article presents an approach to the organization of the knowledge base of intelligent system of pragmatic identification of information of a confidential nature, using two models of knowledge representation. We have defined a subject field to meet the challenges of which the intelligent system was meant for. The article describes the ontological model of knowledge representation used for formal representation of domain concepts in the knowledge base. It presents an indicator of exactness of meaning reference to a concept of domain meaning. The article describes a confidence index for each rule from the rule base that characterizes the measure of the likelihood of a conclusion when a rule implemented. It presents a general structure of the rules base, conditions of execution of each rule of conclusion. To accelerate the work of intelligent system a parallel search for the rules in the knowledge base is to be applied. In conclusion, the algorithm of parallel search is described
In the article, we develop the software for process of
confidential data detection based on the knowledge
bases technology. The algorithm of detection of
confidential data in the electronic documents
transferred outbound of protected information system,
due to application of linguistic technologies of the
thorough text analysis is presented. The estimation of
computing complexity of the developed algorithm is
made up. The developed data structures and algorithm
are realized in the programming language C++.
Results of the experiments, confirmed workability of
the developed algorithm are presented. The performed
experimental researches of the developed algorithm
have shown its practical applicability. The estimation
of quality of confidential data detection is made up.
The obtained estimations of detection quality have
shown, that the developed structures of data and
algorithm provide more effective and qualitative
solution of problems of the confidential information
detection in electronic documents, at due to application
of knowledge bases technology where the subject
domain of the analyzed information is considered.
Distinctive feature of the developed algorithm of
confidential data detection is the use of rapid access to
hashed concept ontographs simultaneous
implementation of knowledge base rules, which allows
raising indicators of completeness and accuracy of
detection. A scope of application of the developed
software is the protection frames of the information
intended for revealing of an information transfer
containing data of confidential character in electronic
documents outbound of protected information system
with violation of security policy
