Security is an important factor that must be considered when designing virtual networks. Many of the same network practices that are used in the physical network can be applied to the virtual network. The virtual network provides several advantages to security, but it also introduces some challenges.
The security of virtual machine network traffic is critical along with the security of the VMkernel traffic in order to prevent attacks that may compromise the management, vMotion, Fault Tolerance, and IP storage networks.
Identify the available virtual switch security options.
Select a virtual switch security configuration based on the design requirements.
Apply security best practices to create a virtual network design, separating virtual machine services and the network traffic into security zones based on the design requirements.
