Invisible networks are spreading within data centers. Virtualization of computing hardware is creating these networks of VMs within physical servers. Traditional network monitoring and security measures are unable to see or control the growing volume of inter-VM traffic.
Enterprises are increasingly concerned about the risks of virtual networks, which range from undeterred malware exploits to mixing trusted and untrusted systems. Some have scaled back the scope and economic benefits of virtualization. Others have tried to apply traditional security to the virtual environment. However, key virtualization technologies such as VMotion from VMware break the traditional models of physical network tools. Juniper Networks® vGW Virtual Gateway has been purpose-built to mitigate the risks of virtual networks, while maintaining the ROI of virtualization. A next-generation security solution specifically designed for the virtual environment, the vGW monitors and controls inter-VM traffic, enforcing security policies at the individual VM level. Because vGW was designed from scratch to secure the latest virtualization technologies, it provides the thorough protection and ease of operation missing from traditional physical networking products and workarounds.
In this white paper, we will examine the virtualization issues that challenge today’s data centers and discuss their best options for securing virtual networks.
