The paper considers the construction of secure communication networks and their elements. The analysis of simulation modeling of the communication network segment under attack conditions, the influence of information security tools on network traffic, and examples of calculations are given. The analysis of the method of network traffic optimization is performed taking into account the use of various information security products, as well as options for developing a security policy. The results of experiments under various conditions of information security are given: in the absence of an attack without the use of information security products; in the absence of an attack using information security products; under a DoS attack without the use of information security products; under a DoS-attack with the use of information security products. Several methods for optimizing traffic using information security products are considered. A security policy is considered to achieve a given level of information security in a computer system with a minimum reduction in the network traffic and the cost of information security products.
