The Model for Assessing the Security Level of Instant Messaging Information Systems

Abstract

The analysis of existing information systems for transmitting multimedia messages is carried out, a generalized conceptual definition for describing the architectures of such systems is proposed. The classification of messaging systems and their architectures is given. The key threats that should be considered when developing messaging systems in various application domains are identified. Based on the analysis of threats, a set of criteria has been determined for assessing the architectures of information systems for transmitting messages. A model which allows to make an assessment of parameters affecting the security of instant messaging information systems based on the characteristics of its elements is proposed.
