Modern approaches to enhancing communication security in telecommunication infrastructure

Abstract

This article analyzes modern approaches to ensuring communication security in telecommunication infrastructure. In recent years, the widespread adoption of information and communication technologies, particularly IP telephony, mobile communications, and fiber-optic networks, has brought the issue of enhancing cybersecurity to the forefront. The study examines cyber threats specific to telecommunication networks, including DoS/DDoS attacks, data interception (sniffing, eavesdropping), call redirection (hijacking), and fraudulent schemes (vishing). The effectiveness of various protection measures was evaluated, such as cryptographic methods (TLS, SRTP, VPN), network security tools (firewall, IDS/IPS, VLAN), and organizational measures (user authentication, password policies, staff training). The findings indicate that implementing a comprehensive approach to protective measures significantly increases the stability and reliability of telecommunication systems. The proposed solutions hold practical significance for the development of the national telecommunication infrastructure within the framework of the “Digital Uzbekistan – 2030” strategy.
