Abstract: This report examines important issues related to different ways to influence the information security of file objects, subjected to information attacks by the methods of compression. Accordingly, the report analyzes the relationships that may exist between selected set of known by the moment of exploration attacks, methods and objects. A methodology for evaluation of information security of objects exposed to attacks is proposed. This methodology reports the impact of different methods of compression which can be applied to these objects. A coefficient of information security for each relation attack—method—object is created. It depends on two main parameters TIME and SIZE, which describe, respectively, the attack and the object. The parameters are presented as two separate relations variables before and after the impact of methods of compression. Since one object can be processed by more than one method of compression, different criteria and methods are used for evaluating and selecting the best method of compression with respect to the information security of the investigated objects. An analysis of the obtained results is made. On this basis are made recommendations for choosing methods of compression with the lowest risk with respect to the information security of file objects, subjected to information attacks.
