For every company that develops modern Internet projects, one of the most important tasks is to ensure the necessary level of information protection in its web project. When an Internet project developing company consistently protects its information system, it creates a reliable and secure environment for its activities on the World Wide Web. Damage, leakage, lack and theft of information from the site will inevitably lead to a decrease in the level of trust in the organization as a whole, as well as to problems with the law, which is always a loss for each company. For example, there may be losses from the bad reputation of the developer, the lack of customers, the costs of resuming the stable operation of an Internet project based on the WordPress content management system, or the loss of important information contained in the system. In the paper, an algorithm of the software complex was developed, which includes three main blocks: data acquisition and backup creation, processing of information about the system, and the use of protection mechanisms. A software package has been developed to ensure the security of web projects based on CMS WordPress.

Purpose: design of the passive device of the speech information protection from acoustoelectric leakage channels and study of the characteristics of protection device using a virtual laboratory bench developed in the Matlab environment. Methods: mathematical modeling using Matlab environment. Practical relevance: designed in the Matlab modeling environment: an equivalent circuit of the telephone set, which makes it possible to simulate acoustoelectric information leakage channels, schematic diagrams of passive protection devices for telephone sets that implement protection methods: limiting low-amplitude signals, filtering high-frequency injection signals and disabling acoustoelectric transducers, a virtual laboratory stand for research of the characteristics of protective device. Using a virtual laboratory stand, the main characteristics of the developed protection devices were studied and their performance was assessed when connected to the telephone network.

A significant part of Ukrainian bridges on public roads is operated for more than 30 years (94 %). At the same time, the traffic volume and the weight of vehicles has increased significantly. Insufficient level of bridges maintenance funding leads to the deterioration of their technical state. The ways to ensure reliable and safe operation of bridges are considered. The procedure for determining the predicted operational status of the elements and the bridge in general, which has a scientific novelty, is proposed. In the software complex, Analytical Expert Bridges Management System (AESUM), is a function that allows tracking the changes in the operational status of bridges both in Ukraine and in each region separately. The given algorithm of the procedure for determining the predicted state of the bridge using a degradation model is described using the Nassie-Schneidermann diagram. The model of the degradation of the bridge performance which is adopted in Ukraine as a normative one, and the algorithm for its adaptation to the AESUM program complex with the function to ensure the probabilistic predicted operating condition of the bridges in the automatic mode is presented. This makes it possible, even in case of unsatisfactory performance of surveys, to have the predicted lifetime of bridges at the required time. For each bridge element it is possible to determine the residual time of operation that will allow predict the state of the elements of the structure for a certain period of time in the future. Significant interest for specialists calls for the approaches to the development of orientated perspective plans for bridge inspection and monitoring of changes in the operational status of bridges for 2009-2018 in Ukraine. For the analysis of the state of the bridge economy, the information is available on the distribution of bridges by operating state related to the administrative significance of roads, by road categories and by materials of the structures. Determining the operating state of the bridge is an important condition for making the qualified decisions as regards its maintenance. The Analytical Expert Bridges Management System (AESUM) which is implemented in Ukraine, stores the data on the monitoring the status of bridges and performs the necessary procedures to maintain them in a reliable and safe operating condition. An important result of the work is the ability to determine the distribution of bridges on the public roads of Ukraine, according to operating conditions established in the program complex of AESUM, which is presented in accordance with the data of the current year. In conditions of limited funding and in case of unsatisfactory performance of surveys, it is possible to make the reasonable management decisions regarding the repair and the reconstruction of bridges. Keywords: bridge management system, operating condition, predicted operating condition, model of degradation, bridge survey plan, highway bridge.
