Vulnerability Analysis in a Virtual Network Environment: Implementing Nessus as an Assessment Tool

Abstract

This article examines vulnerabilities in virtual network environments, in a context where organizations have a growing need for cybersecurity and opt for virtualization solutions. These environments present unique challenges, such as infrastructure complexity and resource allocation, which can lead to vulnerabilities not typically found in physical networks. Using the Nessus tool to perform security audits, various critical vulnerabilities were identified and different corrective measures were proposed, such as software upgrades and tighter security configurations. The analyses performed on a simulated virtual network demonstrate the importance of a holistic approach to protecting IT infrastructure, data, mitigating risks associated with misconfigurations. This approach is essential to ensure data security and operational integrity in an increasingly digitized environment.
