Abstract

One of the most significant challenges in modern IT infrastructure management is maintaining the delicate equilibrium between technical debt and security integrity. In environments characterized by rapidly evolving requirements, research and economic priorities often necessitate the deployment of ad-hoc solutions. This process typically results in significant heterogeneity, where legacy systems and sub-optimally configured endpoints coexist. The central hypothesis of this research is that the “freshly installed” state of an operating system – even with a minimal package selection – does not, in itself, constitute a guarantee of security. This study performs a comparative analysis of the security profiles of traditional, monolithic operating system installations versus modern, Proxmox-based containerized solutions, with specific regard to the vulnerability lifecycle and the recommendations of the CIS (Center for Internet Security) and NIST (National Institute of Standards and Technology).
