Secure Virtual Network Configuration for Virtual Machine (VM) Protection



Ramaswamy Chandramouli


Virtual Machines (VMs) are key resources to be protected since they are the compute engines hosting mission-critical applications. Since VMs are end-nodes of a virtual network, the configuration of the virtual network forms an important element in the security of VMs and their hosted applications. The virtual network configuration areas discussed in this documentation are: Network Segmentation, Network path redundancy, firewall deployment architecture and VM Traffic Monitoring. The various configuration options under these areas are analyzed for their advantages and disadvantages and a set of security recommendations are provided.
