Executive Summary

Cloud virtual machines (VMs) offer organizations unmatched speed, scalability, and flexibility for modern infrastructure needs. However, security research highlights significant gaps when these VMs are deployed without proper oversight and management. The primary risk stems from VMs being left to operate without adequate security controls, monitoring, or patch management—effectively left to 'fend for themselves.' This creates potential attack surface for threat actors who could exploit misconfigurations, unpatched vulnerabilities, or weak access controls. Organizations must implement robust cloud security hygiene practices including regular vulnerability assessments, proper access management, network segmentation, and continuous monitoring of VM environments. Without proactive security measures, the very flexibility that makes cloud VMs attractive becomes a liability that could undermine an organization's overall security posture.

Summary

Cloud VMs offer unmatched speed, scale and flexibility – all of which could eventually count for little if they’re left to fend for themselves
