RESEARCH OF INFORMATION SECURITY PROVISION METHODS IN A VIRTUAL ENVIRONMENT

In today’s world of technological development and dependence, unfortunately, most IT assets of companies remain vulnerable due to a combination of technical and organizational factors, such as outdated technologies, configuration errors and the human factor. These weaknesses become the main entry points for cyber threats, allowing attackers to gain unauthorized access to data, disrupt services or launch large-scale attacks. The lack of a systematic approach to security significantly increases the risks of losing critical information and downtime. Analysis of existing threats, such as DDoS attacks, data leaks and hypervisor compromise, demonstrates the need for a comprehensive, multi-layered approach to protection. The use of firewalls, intrusion detection and prevention systems (IDS/IPS), SIEM solutions, as well as monitoring platforms allows you to effectively control traffic, detect anomalies and respond quickly to incidents. This article examines the issues of ensuring information security in virtualized environments using network protection systems, intrusion detection, proxy server, security monitoring and infrastructure control. Attention is also focused on the vulnerabilities of information systems associated with the use of outdated technologies, insufficient network segmentation, as well as errors in the configuration of security solutions. The comprehensive application of modern security technologies and flexible architectural approaches form a reliable basis for further improvement of information resource protection systems in virtualized environments. A multi-level protection architecture is proposed that integrates modern systems and is based on the concepts of Zero Trust, micro-segmentation and multi-level protection (Defense in Depth). The tests conducted confirmed the effectiveness of the implemented security measures for the developed system, the results of which confirmed the effectiveness in detecting and preventing modern cyber threats, ensuring reliable protection of critical information resources in a dynamic environment.
