Securing a Virtualized Server

Just like physical servers and networks, organizations need security controls to protect and monitor sensitive data. As noted in this Dark Reading story, some enterprises have overlooked the security implications of virtualizing their environments -- but hackers and security researchers haven't.


Server virtualization is a hot topic for data centers as enterprises, but don't forget the security implications.

"The answer? Get back to the basics. Just like physical servers and networks, virtual systems need security controls to protect and monitor sensitive data to make sure it's not being leaked, intentionally or unintentionally. But instead of physical appliances that can be seen and touched -- and fail -- we now need 'virtual' security appliances. The low profile of virtual security appliances allows quick deployment, utilization of the existing virtual infrastructure, and quick failover and restoration from backup if something fails.

"The primary benefit of specialized, virtual security appliances and products that integrate with the hypervisor is they allow security to regain the visibility and control of traffic that is lacking in most virtualized server environments. Network security vendors like Lancope, Reflex Systems, and Altor have all released products for the virtual environment, offering a range of capabilities from network behavioral analysis to firewalls. As with physical firewalls and network flow data analyzers, you're implementing the same kinds of rules as if the virtual servers you're protecting were physically separated on the network."
