Virtual Infratructures need Virtualized Security

Most companies by now have virtualized a large percentage of its datacenter infrastructure.One mistake that may be made is to rely on existing physical security devices only to protect your virtual infrastructure . A physical servers traffic normally traverses our physical network devices but inter vm traffic may never leave your hypervisor hence an intruder who gains access to one improperly secured  Virtual Machine may be able to compromise additional virtual machines without  being detected by a physical Intrusion prevention  system or firewall,since inter vm traffic flows exists within virtual switches.In order to properly protect virtual machines hypervisor level firewalls are required,these Vfirewalls are virtual comstructs managed like a physical device and providing visibility into virtual network traffic flows.
