Virtualization offers many benefits. However, as pointed out in this SC Magazine article, in the rush to capitalize on these benefits, some organizations may have overlooked the ramifications a virtualized environment has on a company’s security posture.
“Legacy viruses, trojans, rookits, keyloggers and other malware can all do substantial damage to a VM and its host. Additionally, an infected VM can carry out attacks against other VMs as well as other physical servers on the network.
“An effective security strategy for most virtualized environments is to ‘double-down’ on conventional security wisdom, making sure to take a layered approach to security technologies. As the conventional wisdom states, there’s no such thing as a silver bullet that will bulletproof an organization’s security posture. This is doubly true for organizations rolling out a virtualized environment.”
