Limited Choices Are Available for Network Firewalls in Virtualized Servers

The increased use of virtualization solutions that support an internal virtual network, combined with the increasing deployment and use of network firewalls within the data center, is changing how network firewalls are deployed to provide security in the data center. The increasing use of virtualization, particularly in data center environments, will lead to new potential attack paths. In response to threats that can originate from within the enterprise, data centers are now a part of the extended DeMilitarized Zone (DMZ). To protect critical servers and data in virtualized environments, the use of network-based firewalls and IPSs that run in those environments will be required to maintain security segmentation.
