“…The accuracy is the degree of conformity of the received information with transmitted one. The accuracy assessment is the probability of the correct reception, equal to the ratio of the number of correctly received message symbols to the total number of transmitted symbols for a certain period of time [3].…”

Abstract. In connection with the rapid development of telecommunications technologies, the provision of communication quality parameters and its reliability are very relevant. In this regard, the new approaches to the operation and control of telecommunications networks are required which are inconceivable without an integrated approach to solving this problem and developing a control system not only for the network state, but also for the quality indicators of its operation. The idea of the work is to develop the control system that is able to determine the principles of strict monitoring over the telecommunications network of Kazakhtelecom JSC in Karaganda. The analysis of the key performance indicators of the telecommunications network showed that after the implementation of the Network Management System hardware and software complex, all values of quality indicators meet the regulatory values. It allows monitoring and controlling the telecommunications network at various levels of operation of basic and auxiliary equipment in a wide range of work.

“…This can happen in case of password leaks, low password IJEEI ISSN: 2089-3272  database security, the use of outdated hashing methods such as MD5 and SHA1 [10], or access to the password database by phishing those users who have access to the password database. For example, frequent traffic leaks in the IP telephony network occur due to the use of outdated hash functions [11], which do not provide strong protection and as a result lead to loss or theft of traffic, in addition to attacks on personal data [12]- [16]. The use of rainbow tables in practice is not limited to attacks, they can also be used as a mechanism for cryptanalysis of telecommunication systems or recovery of a forgotten password.…”

The research of the strength of a hashed message is of great importance in modern authentication systems. The hashing process is inextricably linked with the password system, since passwords are usually stored in the system not in clear text, but as hashes. The SHA-256 hash function was chosen to model the attack with rainbow tables. An algorithm for constructing a rainbow table for the SHA-256 hash function in the Java language is proposed. The conditions under which the use of rainbow tables will be effective are determined. This article aims to practically show the process of generating a password and rainbow tables to organize an attack on the SHA-256 hash function. As research shows, rainbow tables can reveal a three-character password in 3 seconds. As the password bit increases, the decryption time increases in direct proportion.

“…But, despite the many advantages of the Asterisk PBX, the problem of secure data transmission in the network, especially when it is scaled when the PBX acts as an independent service system, remains not fully understood [28][29][30][31][32]. Most research is currently focused on protocols and encryption [33][34][35][36], as well as the quality of the transmitted voice traffic [37][38][39][40]. This does not eliminate the main threats as the attackers are currently focused on something else [41].…”

The research problem described in this article is related to the security of an IP network that is set up between two cities using hosting. The network is used for transmitting telephone traffic between servers located in Germany and the Netherlands. The concern is that with the increasing adoption of IP telephony worldwide, the network might be vulnerable to hacking and unauthorized access, posing a threat to the privacy and security of the transmitted information. This article proposes a solution to address the security concerns of the IP network. After conducting an experiment and establishing a connection between the two servers using the WireShark sniffer, a dump of real traffic between the servers was obtained. Upon analysis, a vulnerability in the network was identified, which could potentially be exploited by malicious actors. To enhance the security of the network, this article suggests the implementation of the Transport Layer Security (TLS) protocol. TLS is a cryptographic protocol that provides secure communication over a computer network, ensuring data confidentiality and integrity during transmission. Integrating TLS into the network infrastructure, will protect the telephone traffic and prevent unauthorized access and eavesdropping.
