Access "Virtualization security plan: Replacing physical separation"
This article is part of the November 2010 Vol. 1, No. 1 issue of Building the infrastructure to enable flat Data Center network architecture
As virtualization takes off in the data center, network and server managers must implement a virtualization security plan that ensures stability of core applications running on virtual machines. That may require the use of a combination of security tools. When the New Mexico Human Services Department implemented VMware-powered virtualization across 80% of its 160 Dell servers, the IT team knew it could no longer depend on physical separation as a means of securing each server. That approach would only limit virtual machine (VM) movement in the data center, diminishing the overall benefits of virtualization. Another complication was that existing network firewalls and intrusion detection or prevention systems (IDS/IPS) didn’t work within the virtualized setting. So Gurusimran Khalsa, systems administrations bureau supervisor for the department, began seeking a virtualization security plan that would enable centralized access control, logging and firewalling within a virtualized setting. He developed a strategy that combined the HyTrust Appliance for ... Access >>>
