With wide deployment of new mobile network equipment and increasing requirements to network reliability, the destroying events such as power outage or disaster have become a serious threat to the current mobile networks. Such events can at the same time destroy all equipment in a particular land zone and affect network services for a long time. That is why so important to develop disaster-resilient network for future highly survivable communication services. In this paper, we focus on using technologies such as Software Defined Networking and Network Function Virtualization to minimize equipment failure risks and propose protection approach for fast recovery of network nodes after disaster happens.

Existing vulnerabilities of Web system threaten the regular work of information systems. The most common Web system vulnerability is SQL injection. There is known approaches to protect Web applications against SQL injection attacks in the article. To improve the Web software security it is developed defense mechanism that protects Web resources from SQL injection performing. To implement this software it is used PHP, JavaScript and formal language theory known as regular expression. As a result it is received a software tool which allows to protect Web software from SQL injection vulnerability. Developed software tool allows user to protect his own Web application from an attack with using SQL.

This paper presents the application of equivalent replacement method for the development of dual-band microwave power distribution devices with arbitrary power division ratio in different frequency bands. The expressions allowing to replace with the equivalent circuits of T-type and P-type a transmission line segment having a different values of characteristic impedance and electrical length at different frequencies are received. For the obtaining of such expressions the method based on the input reactances of reduced partial circuits of even-mode and odd-mode excitation is offered for using. Expression for determination of parameters of the loaded line segment which is used for realization of a reactance with two values of resistance at different frequencies is received also. The examples of calculation and simulation of a dual-frequency power divider and rat-race coupler with power division ratio equal to 2 and 1 at frequencies 2 and 3.6 GHz are given.

The necessity of using the mechanisms for choosing telecommunication strategies is substantiated. It's done as a condition for effective usage of available frequency and energy resources to achieve the main goal of multiservice system - scenarios implementation for information transmission. Definitions of the “scenario” and the “strategy” concepts are proposed in the context of information society.

In modern telecommunication networks very acute problem is an increasing of scalability. The most effective solution is the usage of hierarchical routing which assumes that decomposition of the network into areas. The paper proposed the method of hierarchical inter-area routing based on the goal coordination principle. The proposed method is based on flow-based model of inter-area routing. In numerical examples the work of proposed method of hierarchical inter-area routing was demonstrated.
