Microsoft Azure
Azure administration often becomes a security and connectivity problem before it becomes a compute problem. This section focuses on practical controls around virtual machines, network reachability and administrative access. The current guide shows how to restrict inbound management access to a known source instead of exposing a VM broadly to the internet, and it explains the checks an administrator should make before and after changing the rule. Use these notes when reviewing Network Security Group access, troubleshooting why a trusted workstation cannot reach a VM, or tightening a temporary administrative rule after maintenance is complete.
