A Systematic Approach to the Analysis of Threat Models for Technical Information Leak Channels

Abstract

A comprehensive model for the systemic analysis of threats of confidential information leakage through technical channels (TIC) is proposed. The model includes formalization of leak sources, propagation channels (electromagnetic, acoustic, acousto-optic, etc.), and interception methods. Based on the FSTEC of Russia registry, a classification of TIC threats and their parameterization were performed. A probabilistic-statistical model was developed for quantitatively assessing leak risks and optimizing the selection of information security tools.
