This article serves as the first part of a series dedicated to securing virtualized systems in cloud environments. The primary focus here is on the essential security principles…

The Foundation of Visibility in Cloud Environments In traditional on-premises infrastructures, security teams often rely on centralized tools for logging and monitoring. These systems tap into routers, switches, firewalls, and other network devices to collect logs and monitor real-time traffic. However, cloud environments present a different set of challenges. In cloud platforms, resources are distributed, dynamic, and often ephemeral. Instances can scale up and down automatically based on demand, APIs are heavily integrated into operations, and infrastructure is commonly defined as code. These characteristics offer unique advantages, but they also…
